- 3 Brownells M16-A1 Barrel Physicals
One Barrel had a Chamber Issue and it failed the Front Sight Base Alignment Check.
All three Upper Receivers are 1970 era Colt. After the video I swapped around Uppers and got the same results. The Uppers are worn but pass all Alignment Checks. It's not the Uppers that caused the FSB Alignment failure.
Since these Barrels are so hard to find, we decided to repair the bad Barrel instead of returning it to Brownells. We repaired the Chamber Issue with a 5.56 Flex Hone and corrected the FSB by re-aligning the FSB, reaming the holes, and fitting oversized taper pins.
We will do a separate video showing the repairs.
Chad walks into a gun store with a backpack slaps it on the counter pops out all his gauges and says I'd like to take a look at all your rifles
This made me smile.
You should know all his gauges would never fit into a single backpack. He would back his trailer up.
@@heatherkelley8115 very true but you always need a bug out bag lol
He has me walking around with a backpack full of different brands and generations of mags and my own buffer tube when I’m just buying an off the shelf lower. The gunshop clerks always look at me like I’m nuts when I’ve tried 12 different magazines and known ‘in spec’ receiver extensions on a lower. 🙈😂
Next I’ll start carrying a known ‘in spec’ pivot and FCG pins sets. lol
Just doing an endshake and timing check on a revolver pisses off some gun store guys. Of course if they get annoyed, I don’t buy the gun…
Outwardly you would think these subjects would be boring or tedious but when I watch I hang on every word like I'm watching one of the best action films of the decade. Thank you so much for what you do and the cohesiveness of your explanations. You were born to teach and break things down for us dummies. It's a fantastic gift and one that you use extremely well. Much of these subjects of the ongoing of the rifle would be a very big drag if anyone else was explaining them. I'm not trying to over do it, but you make it look super easy. I wish I had one or two tools that you do.... Anyway, thanks again for you calm and integrity of what you do and all you do for us. God bless
Every video here I get more envious of his tool collection!
Thank you for not letting all this information leave with you. You are important to the community.
I always thought building a clone from a USGI parts kit would take my thirst for the M16A1, but I was wrong, now I'm on my 2nd build lol, can't get enough of them!
Yep. It gets bad to worse. We have several retro projects in various stages.
@@SchooloftheAmericanRifle it's doubly hard as a nj resident building retro builds but I got a nice little collection bastardized for nj - Have a 601 (I repainted from brownells neon green) a 604 , XM16E1, M16A1 , M16A2 , Colt 654 to simulate the XM177 , did a bad bakelite furniture set (looks nice but fancy) used on my 308 build ...
Yeah I’m on my 3rd build and I just started 9 months ago. It’s the addiction 😆
Continued proof that even a quality company can & will let a stinker slip past, especially now with the way the market is. There are a lot of sellers that wouldn't even bother checking for 'clocking' of the FSB & even more buyers that just wouldn't care.
Thanks for the educational & informative videos!
The ole Mk.1 Mod.0 "Eyeball" is good at telling if something isn't right. The gauge tells you with certainty.
Chad, I hope Brownells is watching.They need to get with their vendor on quality control or try another vendor. I always look forward to your videos. They are extremely educational and relaxing. I was waiting for Rebel to chime in! Best to you and your family!
Really nice video and top notch camera person, thank you. Blessings.
The one person that gave a thumbs down didn't get one when the were on sale. Lol
I have some haters who subscribe to thumbs down. It makes me laugh.
@@SchooloftheAmericanRifle Well haters will hate! I appreciate what your doing.
@@SchooloftheAmericanRifle Must be some hard core AK guys that can't get over the fact the AR is a better rifle.
@@SchooloftheAmericanRifle its insane anyone can hate on you or your channel. You literally just deal in facts.. cold hard facts.... numerical facts. Some people just want to see the world burn I guess. Keep up the amazing work man, just discovered your channel last night and ive been watching your videos for the past 10 hours
Outstanding...a bit disappointing to see the one new barrel fail.
Great run down on the checks... 🤠
Lol her whisper commentary is awesome. I heard that o my gosh on the 3rd fsb check.
Yep. That one induced a reaction.
That was my favorite part.
Oops! I didn't even realize I said that out loud until we watched the video. 😬
Always a good day when chad posts!!! More vids pleassseee chaddd.
SOTAR has the ultimate set of tools. A collab with Small Arms Solutions would be epic.
Chad,
GREAT to see you back on YT!!!!!
I really appreciate what you do, love seeing inside the bore and chambers. I'd like to see more of that, show us good barrels, what normal wear looks like, what is clean or dirty, damage from improper cleaning, etc.
I got a PSA 20" upper, with FN CHF chrome lined barrel. I had read a number of reviews where the front sight base was canted. The front sight base looks straight, but right away I noticed the right ear is thicker than the left. Who ever machined the notch for the front sight, did so off center. I probably could have returned it, but 6 clicks on the rear sight and I was zeroed.
I "think" I'm zeroed, it was cloudy that day, I'm almost 50 and need a brighter day. My range has a roof over the tables, add some clouds and I'm not as accurate.
I'M SO HAPPY MORE VIDS ARE UP,!!!
Thank you.
Telling people in a video how to check their retro AR-15, in your socks, in your personal armory.
Bro, I’m jealous af.
Keep em comin.
Good to see some new tech inspection video from you. Thank you!
It does seem that they rushed these out due to demand. The canted FSB issue is fairly widespread. I got lucky and mine is fine, and Brownells will indeed make things right, but it's still a little disappointing that so many of them are showing up with issues. That said, I was incredibly happy to see these come back; my XM16E1 clone build had been stalled sitting in my garage for months.
I seem to have got a good one as well. Only had it to the range once and seemed to be dead nuts with only mechanical zero. I think everyone should own a 20" with triangle handguards. Boy do I love the triangles!
You know your stuff.
I did get one of these for a customer and it measured out ok. Prior to this year Brownells use to sell just the barrels without the FSB attached. Went through a batch of 50 of those. It's a relatively decent barrel.
Awesome video great camera work was able to see everything, would love to see the followup video with the oversized pin install/even a regular video on tapered pin installation would be great to see, thanks for sharing
I appreciate the compliment on the camera work!! ❤️
@@onna-day7047 Its extremely underrated in 9/10 gun work videos. You and Mark Novak have it right, what a standing person in front of the work sees is entirely different than what the camera sees, thank you for doing it right! I subscribed to see what comes, thanks again and good luck.
I always enjoy your videos.
Love your videos. Need to sign up for classes. Thank you.
I wish I would have seen this video when I bought my barrel from Brownells... Mine was canted severely maxed out windage and still hit a foot off the target. Great info I love this channel learned alot from it
I have one of those barrels and had it mounted on an M16A1 kit. So far so good! Really love the retro build weight compared to my tac'd out AR.
Another Excellent Video!!!
Thanks!
Nice work Chad. Very good video.
I learn so much here. Thank you
DAMN I LOVE THESE VIDS. SO EDUCATIONAL, YOU LEARN A LOT FROM THESE FOR SURE, T.Y. SOTAR.
Keep ‘em coming ! I’ve been watching all your videos and this is by far hands down the best content of its kind on the tube 😎👏🏼
Keep these videos coming!
Slightly disappointed you're not gauging another burrito this Thursday morning, but I'll give this a like anyway lol
Just noticed I have not gotten any notifications from your channel thought you hadn’t made any new videos.
great video thanks!
Amazing content !
Your workbench is a beautiful.
When everybody is focused on flat top free floating ARs. The machining and calculations that are needed to properly calculate a front post site and indexing the barrel into the receiver seem to confound a lot of builders. It took a lot of tweaking to get this right and it will take a lot of practice and engineering to get it right again.
Very interesting. It would be helpful to see different wear and damages in the bore to know what to look for or what to call good and what wear is about the ball park of what round count.
Mine was worse than your third one. It was where your rod point was at the “ear” of the sight. I could not figure out why my rear sight had to be all the way to to the left to hit a 12” target at 50 yards. So after just not shooting it for about a year, I bought a long drill bit at my local hardware store and did basically this same test. I ran the bit back and forth on my granite countertop to check for straightness after eyeballing at the store. Luckily got a relatively straight bit. Brownells took the barrel assembly back and replaced it even after I had written it off and left it in the safe for 18 months
It would be very helpful to see a chamber that needs polishing vs. one that’s good to go. I generally don’t follow the “polish it every time” school of thought, but there do seem to be a lot of tooling marks in chambers even in barrels that are otherwise fine.
First post?? Looking forward to you examining some of these parts. Thx
I would like to see the current Colt 'CR' prefix guns on your bench at one point. Curious if there is any changes and especially curious about your thoughts on those current production guns.
They were produced by Ballistic Advantage for Brownells.
I remember seeing some blem receivers a while back where the rear A1 style carry handle sight was milled out of spec so the sight channel was off farther to one side
Look at his reply to "W B"
@@MWhite-dv1uu noice
These are 1970 era Colt uppers. They are worn but pass all alignment checks. It's not the uppers that caused the alignment failure.
@@SchooloftheAmericanRifle yeah I was thinking they were older receivers. Great video as always sir
@@ethan5.56 thank you.
I’d like to see you ream and fix the front sight. I’m also curious if there would be a way to check alignment/cant on a flat top receiver?
Detachable carry handle
I get the Delton pencils, always true but .750 at sight
So you would consider these type of barrels concentric to bore and therefore safe for a can?
Great educational videos, always enjoy watching them! What drill press would you suggest for dimpling barrels/drilling to pin a gas block?
Any budget model should work for this particular task. We have a cheap Sears (Discontinued) model in the shop that does a great job with SLR Dimpling Jigs.
@@SchooloftheAmericanRifle thanks, appreciate it.
Regardless of what you end up getting, I'd make certain that it's parallel to the column, and at a perfect 90 in every direction to the table before you use it. Ideally you'd want to use a gauge pin or some other known straight and round rod, along with a test indicator of some sort. Another good option would be a precision machinist square and gauge pin or other rod. In a pinch, you could also use a known good square and drill bit, just realize it won't be as accurate or precise.
That lower 0:45 😍😍😍, just beautiful
Thank you.
Have you ever done a physical on a ks47 by Palmetto State Armory?
@brownells hope you’re watching.
;)
With a front sight alignment issue like that could the barrel extension be clocked to try to alleviate the issue or would that mess with your head spacing
Concerning your alignment gage for the front sight, a couple of questions. How certain are you the carry handle channel provides that straight of a platform to determine the front sight is that off? Have you ever zeroed the rear sight and fired a group confirming this system is in agreement? Have you ever swapped uppers after using the gage and found a different alignment?
I would check the alignment of the one barrel in a different upper receiver just in case. Like you said it's a mishmash of parts that goes into the alignment so maybe it doesn't mix well with the tolerances of that uppers carry handle/sight.
Check the description!
Is this barrel going on your 601 kit you did a short series on 3 months ago?
20:23 « OH MY GASH 😰 »
I have a brand new complete upper and while changing the flash hider out I noticed the muzzle is fairly magnetic, enough to pick up a couple paper clips. Should I attempt to demagnetize it or is there a chance it’ll get hot enough shooting it to demagnetize on its own?
I was about to order one of these, they’re sold out
They sell fast. I saw a notification in the Brownells Facebook page and grabbed some up.
I want to see a complete. Perfectly guaged rifle.
how good is delton for there front sight alignments? ive decided im going to buy one of their m4 barrels after my PSA m4 barrel came with a canted and slightly deformed front sight base that they refuse to replace. its been at PSA for "repairs" longer than its been in my own hands
Great video as always. Looks like you’re using head space gauges that don’t require you to remove the ejector or extractor. Where can I get those?
I make them for my shop and classes.
I just finished building my 3rd AR. They are chambered in 223 wylde, 556 and 300 Blk. I want to be able to check headspace on them. I read in the forums and people say just say get the Colt version Field gauge and if it doesn't close your all set. Do I need the GO, NO GO and Field or can I get by with just the Colt spec Field gauge. Also will 556 gauge work on 223 as well? Thank you sir
Good news is brownells will replace that one barrel
Agreed
Any plans on making the video on distressing the finish?
Knowing how Brownells like to sub out work, I wonder who’s doing the sight install/pinning..
So many canted sights, sounds like TNTE is doin’ ‘em. LOL!
They must have had a bad run of these. The one I got is canted pretty bad. They have not been in stock since July. Completely SOL.
Could put a free float hand guard and low profile gas block and have a good barrel set up on out of spec front site
Tight chambers and rushed shuddy production.....wow...that is real 1967 retro authentic LOL
Did you make the video on the lower yet??
Could the upper receivers be off and not the FSB? What about swapping the upper that was with the barrel that gauged correctly with one of the barrels that did not gauge correctly and see how that does? I have seen videos of uppers where the carry handle area where your rod sat not being machined perfectly centered.
Forgive me if this suggestion is dumb but I was curious what the Misaligned barrel would have looked like in the reciever that was in good alignment with its barrel? Or is there no variable in index?
Not a bad suggestion. We did this after the video and had the same results. We listed a few extra details in the video description.
Thanks, I forget to scroll down and look for info sometimes. ;)
Faxon makes the barrels for brownells if memory serves me right.
Chamber may look rough from using steel case ammo??
When did you get these barrels? They've been out of stock for a long while lol.
They were in stock for a few hours last week. I just received these yesterday.
Hey SOTAR Do you ever do these kind of videos on the AR10?
I feel like bringing all these tools to a prospective rifle purchase and just nitpicking the hell out of it for a good deal. Like bringing a mechanic to a car sale. 😂 j/k but it would be funny.
I have a Brownells BRN10 20 inch light weight carbine barrel (the one with the milled front sight post) and the chamber is very rough, it puts two parallel deep scratches in the case and a consistent crack in the neck.
Brass cases will jam in the chamber and have to be mortared out after they fail to extract, steel case will mostly extract but the extra energy used to overcome the the chamber's resistance will cause the bolt to slow down and cause feeding issues and won't lock back on empty.
Brownells is long sold out of these barrels so I am very interested in what remedy they propose for your barrel problems.
I have been hoping the two high points that are leaving the scratches will wear down with all the steel case, if not I guess more active measures will be necessary.
It was a GREAT DEAL (glad I didn't buy two :-}.
A caliber specific flex hone may help your barrel. It fixed the chamber on the one that failed the chamber gauge.
@@SchooloftheAmericanRifle Thanks for the suggestion, I will look into one.
You said A1 birdcage with a crush washer doesn't an A1 have a regular split lock washer?
Question from an amateur: Is the gas port hole big enough that you can twist the fsb a bit without covering part of the hole?
Yeah, the hole in FSB is about twice the size of the gas port hole.
Would the chamber sticking issue work itself out after shooting it some? If you don't hone the chamber?
It could in minor cases.
Is it possible for a viewer to send you their AR to inspect? I have a Sionics patrol rifle zero that i bought in 2016 and have a few thousand rounds through. I know that's not a lot for the lifetime of a rifle, and i have had no malfunctions that weren't ammo related. Just curious to know exactly what shape my primary rifle is in.
PSA would send me out a new barrel if i sent them pics of a bore scope. Chipping of the chrome lining
I have a a1 barrel from Brownells, how can I test the front sight alignment without the gauge?
@@eliasaamot573 thanks, I didn't know they would take a return after it had been installed
Thought I heard faxon makes the barrel? I could be wrong....
How do we get a SOTAR patch?
We usually have them for sale on our website. I'll list them as soon as we have more available.
20:28 It's possible the channel in the carry handle is off
Don't some brownells blem uppers theyve been selling recently have that issue
After the video I swapped around uppers. Same result. The barrel is the issue.
What is the size for the field headspace gauge you use? NATO 5.56 max at 1.4736”? Or something smaller like the Forster HG0223f “field” gauge at 1.4696”. My thought is to buy a 1.4646”gauge for go and maybe the 1.4696” for no go check. If it closes on the no go check at 1.4696”, then maybe buy the NATO 5.56 max at 1.4736”. This is an attempt to save money as they are expensive.
Where do you get all your tools for this 4:59
Do you offer gunsmithing services or just classes? Is there a way to get a rifle inspected by you?
I offer AR services. Taking in new work is on hold until I catch up on my backlog. I'll announce on my website when we take in new work.
@@SchooloftheAmericanRifle I understand. Do you give quotes individually or do you have a general sort of price list?
@@Tunechi_Lee I do offer AR Services as a package/flat fee. It's a full tear down, inspection, gauging, fitting, and reliability service. I notify the owner about parts that fail and let them decide if they want to replace them. It takes me about 4-5 hours to do each AR, so it's not budget friendly.
I only list the prices when I'm able to take in work.
@@SchooloftheAmericanRifle Thank you so much for replying. Will keep an out on your site for any updates.
What's up with the video to distress receivers ?
"Can't" tell us who makes the barrels, or "won't" tell us? Curious if you know but are protecting the maker, or genuinely do not know who makes them?
I shot the rifling outta one at like 4-5k , granted I did run that gun hard it wasn’t anything it should’ve been able to handle though
Y 360p?
quality is so hard to find these days...
10 rounds fired thru barrel.
👍
Why am I not subscribed yet what's wrong with me.
I wouldn’t trust brownells with my life! Not in a long shot! Bcm all the way
Shame the one didn't pass.
These are going to look awesome when finished
