This is my first video seeing of yours. If the rest are of equal quality then you’re a criminally underrated channel. Found it randomly when looking into expo arms buffers.
If you suspect a buffer adjustment may fix your problem buy the H3 buffer. Using the different combination of weights between your standard buffer(3 lighter steel weights) and the H3(3 heavier tungsten weights) you should be able to come up with a combo that works for just about any AR.
An adjustable gas block can cure most of these problems. Heavier buffer to deal with over-gassing? Just reduce the gas.Under-gassed? Lighter buffer and tune with gas block. Covers a huge range of possibilities. The idea is to use the least amount of gas to cycle the rifle. Less gas fouling, less gas-face, and more gas pushing the round. Also the state with the the least recoil. No AR should be without an adjustable gas block. Best $60 you can spend on an AR.
Really liked the video. Good for a new AR owner. I’d love to see all of this along with a brief comparison to those “quiet” buffer options where some seem to be adjustable while others seem to be fixed weight, which makes choosing more difficult.
I had to watch about 10 videos of guys droning on forever with little good info before I found this one. Great job and thanks for keeping this straight to the point.
this is exactly the information i need. thanks! i just grabbed a PA-15 multi. have been looking into just a few things to help it run smooth. i dont want to add a bunch of accessories. i just want it to be dependable.
This was the best explanation I’ve ever heard on this topic! Well done. I have a Spikes H2 on my 14.7” mid length system. I also added an adjustable gas block. Ejection pattern is at 4oclock on 62 grain. Softest recoiling rifle I own! I am building 11.5” carbine. Also going with an H2 buffer, and also adding an adjustable gas block as I may add a suppressor in the future!
thanks for the great video. Subscribed immediately. I combined a V Seven 11.25 308 Upper with a LaRue lower and put a Tailhook plus a Sylvan Arms folder on it. I was worried about the buffer spring and weight. After watching this video I chose spring and weight and it runs like a dream!
This was an excellent video thanks for putting this together you answered a lot of my questions. The one area that I am still in the dark on is the spring strength! I have heard to smooth out recoil go with a lower buffer weight and a stronger spring. Since the buffer and spring work together to slow the momentum of the bolt and then return it to being in battery it would be really helpful to understand how to incorporate both decisions (selection of a specific buffer and spring ) to optimize felt recoil and ability to execute fast followup shots.
This guy is basing the buffer weights with the use of a standard mil-spec buffer spring.....Or he would have mentioned that....Even just using an extra power spring with mil-spec weight buffer would slow the energy. If you really want to learn about buffer systems don't hesitate to call Sprinco....They are one of the best in the business....They will tell you to start with a standard set-up and tell them what's happening from that point. Your rifle has many tunable options and the buffer is the easiest and quickest.....Unless you have built it urself and used an adjustable gas block your options are limited and they can help......Wilson Combat is another genius company with awesome tech advice. Good Luck and keep on shooting!!!!!
@@ARBuildJunkie I'm always interested in any testing of inexpensive AR related items like PSA parts or Primary Arms optics. I have a respect for the top tier equipment but not a wallet that can afford building with Knights/BCM/Hodge. I carry a Glock and a Colt Defense sits by my bed, but everything else is cheap/beater/home brew guns for fun and I'm always looking for good reliability out of something that I can afford.
Great tutorial. I noticed my brass being thrown forward of the firing line just the other day. I figured something was wrong and since it was gifted to me I was going to tear it completely down. My gut feeling is they used an off the shelf carbine buffer. If that the case I'll switch out o a H3 and see what happens. Very good tutorial.
I tried an H-1 on my rifle when I noticed it ejecting into the 1:00-2:00 area. Next range trip I had the first "short stroke" ever with that rifle. Went back to the lighter buffer....no more short strokes. good luck...maybe your rifle will like the new buffer.
My 3 Colt m4a1socoms came with h2 buffers my 2 Colt 6920s had h1 buffers.I replaced the h1 buffers in my 6920s with h2s.A properly sized gas port on a carbine and the use of good ammo should be able to function better with h1 or h2 buffers.
Just noticed you missed a rubber pad (RP) when you put the together. You go buffer body, RP, weight, RP, weight, RP, weight, and end with buffer bumper. Basically you're trying to avoid any metal to metal contact with the fronts/ends of the weights.
Have a AR never shot, not done with it but the actual barrel is only like 12" long with a 4" flash/break. Not sure how they measure barrels on these. from chamber start to end of rifling? Anyway for 5.56 nato is a H1 about right?
so ive been raised shooting guns but never really knew exactly what happens between parts but as ive gotten older ive understood alot more but my question that i havent found an answer to is what happens if the polymer tip on the buffer is broke
Very nice Video, thanks. Can you do one on selecting Carbine vs A5 vs Rifle length Systems? I currently have a Carbine Buffer on a mid length 14.5". I recently put together an 18" Rifle length Upper to use on the same Lower. it seems to cycle just fine, but I was looking at the Buffer system and wondering if the "A5" variety would be more appropriate.
Very new to AR15s and building my first one. So buffers are always based on the gas system correct? For carbine length I need a carbine buffer and so in?
hi ive been searching around for the correct answer for my build. I have an AR15 carbine build with a 16" barrel with a heavy duty competition barrel much thicker and heavier than factory sized barrel, it is also has a hard recoil even with a muzzle break making me believe it may be over gassed as well. I was hoping to swap out my buffer system and see if that helps at all. but I don't know what size or style to go with for my configuration.
Nomatter what I do, my ejection path is at a constant 1-1:30 position. I'm able to cycle from 3oz all the way up to 5oz. It seems the heavier I go, the less distance the round will be thrown but still all in the exact same direction. What's crazy to me is that when I go with the 5oz weight I can still cycle lower power 223 like pmc bronze and the rifle will still lock back on empty mag but with even low pressure to higher pressure rounds when using the heavier buffer the rounds fall out of the rifle in such a silly looking way like a little brass turd plopping out right underneath my rifle. I ended up just going with 4oz because it seemed to feel the best and also I have less worry of any malfunctions. It's crazy to me how much more my AR kicks with just 1oz less buffer weight. You would never think you could ever feel something with that little difference. Rifle is a 16" Ruger AR 556. Switched out their buffer and buffer spring with a sprinco carbine white spring and buffer that's customizable as well as switching out their bcg to a son's of liberty gunworks complete bcg.
Sounds like your gas port is so oversized that no amount of buffer weight or heavy spring can compensate. You will likely need an adjustable gas block to tame that beast. Check out this video from SOTAR for an in-depth understanding. czcams.com/video/eAuTHPdUchU/video.html
What Buffer & spring would you suggest for a 450 Bush with a 20" barrel? Im having cycling issues (failure to feed & sometimes extract) but i don't have a table full of buffers & springs to test, so before i go spend a lot of money (ammo included) i would like an expert opinion.
I totally laughed my ass off whenever somebody says 3.5 is a heavy buffer. That is not even close to a heavy buffer. Back when they only had two different sizes yeah it was. But I went to a 13 Oz buffer and a 308 recoil spring in my foxtrot Mike 45 carbine.
I don't know if this is really a question, or just info for you to maybe address in some other Buffer-centric video sometime. I'm a novice to building on AR-15 platform and usually do a lot of research before buying each piece. In building an AR-15 Pistol in 9mm, I got the Armaspec Sound Mitigation AR-9 Buffer (ARM158-9). What I discovered was that the guide rod was so damn long, I could not cycle the BCG back into the buffer tube far enough. Saw on a blog somewhere that a SME was helping another novice and speculated that he had gotten a rifle-length buffer kit for a carbine-length stock/brace. I didn't see anywhere in the specs of this buffer where I could have caught that mismatch. Is there ever an end to the countless fuck-ups before learning all that is needed to know? ;-) GREAT VIDEO! You're a great organizer and presenter of straightforward content.
Does the buffer weights supposed to slide back an forth inside the buffer tube? One of my rifles does it, doesn't help with stealth mode, while carrying it quietly. Thanks
Issue: 9.5" 300 Blkout, standard spring and 3.0 oz buffer. Suppressed. Runs supers just fine. Short stroking on subs. Replaced spring with springco 25% reduced yellow spring. Now cycling. Trying to wrap my head around the physics of it. Did I put a bandaid on issue?? Or was I correct in reducing spring tension?
14.5 mid? I haven’t dug deep on the problem yet but could it be the buffer? The rifle cycles fine and I’m getting good ejection but it wont lock back on the last round. Any suggestions?
Thanks you! I have a 300blk and it’s my first AR. I wish I’d have went with a 5.56 for my first build but I did it backwards. I took my first Carbine training classes this weekend and used my 300blk the first day. I always thought my gun recoiled violently considering what I’d heard about ARs leading up to my purchase. It wasn’t bad when standing up, but when I got into prone or when I’ve sat in benches at the range. The shit actually hurt when it would recoil. The trainer said my gun was way over gassed. The second day I used one of their 5.56 mid length gas systems and OMG, it was soooo fucking beautiful to shoot I ordered one that night. So for a 300blk that I only strictly intend to shoot supers out of, what weight should I go with? I really do NOT want to mess with reliability at all obviously as this is my home defense rifle, but I feel like fixing the harsh recoil. My gun had malfunctioned twice within 20 rounds of each other and the trainer said it was because my rifle was to over gassed, after I lubed it up really well I didn’t have another malfunction for the rest of the day. I also hadn’t heard of over gassing causing malfunctions. I’ve heard it can cause excessive ware, but I was under the impression that over gassing was to actually promote reliability not hamper it. Help me out lol I just want my rifle to be perfect is that to much to ask! Lol
Check out Strike Industries' Optimus Modular Weight Buffer. You'll be able to change the weights very easily for someone that is a beginner. Just unscrew and fill up. That way you do not have to guess what buffer weight would be best, you can test out each weight without having to buy multiple or having someone tell you what they think would work best. It also helps for any future builds, just swap out the buffer with the Strike Industries and then buy whichever weight works best based on the results.
Just bought a FN - 15 5.56 carbine M4 ? .......... was told to use xm193 ... 55 grain ammo ...... is this right ? Only ran 100 rds thru it so far was told to run 750 before I do anything to it ........ brass is mostly going behind me at around 5 o'clock
What about the weight of the bolt carrier assembly though? No one ever discusses that part. Mine needs a heavier buffer but not sure to get h1 or h2. Mines all commercial stuff including the bolt carrier assembly and a16” heavy barrel with a2 sight and carbine gas system. Stock used to be fixed rifle but was changed to collapsible Tapco a long time ago. Im considering just buying the 3 piece set of tungsten weights and play around with it and maybe a Wolff extra power spring and just start with the spring then get into the buffer if needed. I can get both for $23 ish plus tax and shipping which is still cheaper than a brownells heavy buffer that may or may not fix it. That’s more than enough weight without a doubt and gives me a lot of adjustment. But is there any difference in mil spec vs commercial diameters on the buffer weights or buffer?
I got a Colt H buffer to try in my Smith and Wesson. That's what's in my Colt 6920 and I like how that rifle feels. Recoil is not a problem with 5.56 but I think Smith opened up their gas port a little and it's overgassed so I'm gonna try it out.
Thank you for all the info, just to double check though.... so if I'm runnin a 10.5 inch ar pistol that's over gased and I may run it suppressed more then not, I should run an h2 or h3 buffer?? Any help would be greatly appreciated.
I am building a 6.5 Grendel with a 20" mid gas system barrel. What kind of buffer tube would you recommend I use? Thank you for your input in this matter.
I have an old 20" barrel A2 style AR. I changed the fixed original stock to an adjustable stock, probably intended for carbine, that has a shorter spring and shorter, lighter buffer. I like the adjustable stock but it doesn't always cycle correctly. Do you think an H1 buffer is the right weight to try?
I have an Aero precision M5-E1 chambered in 6.5 Grendel, 22' barrel, rifle length gas system, magpul prs gen 3 stock and a muzzle break. I also have a Timney trigger with a 1.5# pull weight. My shell ejection pattern is at 1 o'clock and if I don't pay attention to a firm complete trigger pull and follow through, I will have a double (Bump fire)...What weight and type of buffer tube do you recommend to mitigated these symptoms? The rifle runs fine but at higher pressure and brass indications even at lower charge weight loads.
Maybe try an adjustable gas block to regulate the gas. Also you should be running a rifle length buffer tube for a rifle length gas system. Rifle length heavy buffers are not common I believe people run a spacer to use carbine buffers and springs.
This is my first video seeing of yours. If the rest are of equal quality then you’re a criminally underrated channel. Found it randomly when looking into expo arms buffers.
Hey segc
I went with the H2 buffer you suggested from Primary Arms and it runs perfect in my Aero M4E1.
Always smile when I see a Reno May frolicking in the wild.
Simply majestic
If you suspect a buffer adjustment may fix your problem buy the H3 buffer. Using the different combination of weights between your standard buffer(3 lighter steel weights) and the H3(3 heavier tungsten weights) you should be able to come up with a combo that works for just about any AR.

Just noticed you missed a rubber pad (RP) when you put the together. You go buffer body, RP, weight, RP, weight, RP, weight, and end with buffer bumper. Basically you're trying to avoid any metal to metal contact with the fronts/ends of the weights.
what happens if you replace a short pistol buffer tube and put a rifle long rifle buffer tube/system on a AR pistol with 7 inch barrel?
so can you just use an adjustable gas block with a carbine buffer?
Have a AR never shot, not done with it but the actual barrel is only like 12" long with a 4" flash/break. Not sure how they measure barrels on these. from chamber start to end of rifling? Anyway for 5.56 nato is a H1 about right?

What’s the best to run on a 556 10” barrel
So to best reduce recoil the base buffer is best?
Just bought a FN - 15 5.56 carbine M4 ? .......... was told to use xm193 ... 55 grain ammo ...... is this right ? Only ran 100 rds thru it so far was told to run 750 before I do anything to it ........ brass is mostly going behind me at around 5 o'clock
Anyone know about ww-ar15s? I have a stock one and it's great but I suspect it could be better.
After looking at buffer prices, I think manufacturer choice of buffer is often driven by cost.
So a standard 3oz buffer is recommended for a 16” barrel in 5.56 with a mid length system?
What about the weight of the bolt carrier assembly though?
No one ever discusses that part.
Mine needs a heavier buffer but not sure to get h1 or h2. Mines all commercial stuff including the bolt carrier assembly and a16” heavy barrel with a2 sight and carbine gas system. Stock used to be fixed rifle but was changed to collapsible Tapco a long time ago. Im considering just buying the 3 piece set of tungsten weights and play around with it and maybe a Wolff extra power spring and just start with the spring then get into the buffer if needed. I can get both for $23 ish plus tax and shipping which is still cheaper than a brownells heavy buffer that may or may not fix it. That’s more than enough weight without a doubt and gives me a lot of adjustment. But is there any difference in mil spec vs commercial diameters on the buffer weights or buffer?
What about springs?
You need 40k more subs 😉
so .223 55g with 16wylde barrel which buffer weight i get?
H or H2 ?
I got a Colt H buffer to try in my Smith and Wesson. That's what's in my Colt 6920 and I like how that rifle feels. Recoil is not a problem with 5.56 but I think Smith opened up their gas port a little and it's overgassed so I'm gonna try it out.
Once a consistent hand load is established, wouldn't an adjustable gas block remedy most of the cycling issues you were talking about?
Expensive. Buffer is easier.
Thank you for all the info, just to double check though.... so if I'm runnin a 10.5 inch ar pistol that's over gased and I may run it suppressed more then not, I should run an h2 or h3 buffer?? Any help would be greatly appreciated.
Same question. I get a failure to eject on rare occasions and I have a hunch my buffer might be too light.
What would someone recommend for a 16in 308 ar10?
I am building a 6.5 Grendel with a 20" mid gas system barrel. What kind of buffer tube would you recommend I use? Thank you for your input in this matter.
normal buffers are outdated on builds use a jp scs or a armaspec stealth you will have lower recoil then.
Good information. What is the brand of that last one?
KAK same people that make the shockwave blade pistol brace
I have an old 20" barrel A2 style AR. I changed the fixed original stock to an adjustable stock, probably intended for carbine, that has a shorter spring and shorter, lighter buffer. I like the adjustable stock but it doesn't always cycle correctly. Do you think an H1 buffer is the right weight to try?
Get a heavier buffer, extra power spring, or get an A5 buffer system, which is a rifle spring adapted for collapsible stock.
I have an Aero precision M5-E1 chambered in 6.5 Grendel, 22' barrel, rifle length gas system, magpul prs gen 3 stock and a muzzle break. I also have a Timney trigger with a 1.5# pull weight. My shell ejection pattern is at 1 o'clock and if I don't pay attention to a firm complete trigger pull and follow through, I will have a double (Bump fire)...What weight and type of buffer tube do you recommend to mitigated these symptoms? The rifle runs fine but at higher pressure and brass indications even at lower charge weight loads.
Maybe try an adjustable gas block to regulate the gas. Also you should be running a rifle length buffer tube for a rifle length gas system. Rifle length heavy buffers are not common I believe people run a spacer to use carbine buffers and springs.
The M5 cant possibly shoot 6.5 grendel... M5 will shoot 6.5 creed, or the M4 will shoot 6.5 grendel....
whats the best buffer weight for 300blk
