Before anyone starts fiddling about trying to achieve the "ideal" ejection angle, take a close look at the springs in the bolt. If either (or both) are sub-spec, replace them. A "weakened" (or fouled-up) ejector spring will start tossing the empties further and further forward. If the extractor spring is weak, the cases may partially extract, then be "released"; VERY untidy.These two springs are critical, cheap ad relatively easy to replace. If you do not own or cannot fabricate an ejector depressor tool, take the job to an AR-savvy gun-plumber. Added note: If the pressure curve and timing thereof in the BCG is "off", the system will open too quickly and you risk tearing a chunk off the rim of the case because it is still "suck" to the chamber wall. (See also: Pitted chambers). As in a well-told joke or many other activities: timing is everything. Those familiar with belt-fed rock 'n roll goodies will be VERY aware of the importance of GOOD springs. As we used to say in our more frivolous moments; "With a good set of springs,; my machine-gun sings". Two things "kill" springs: HEAT and CORROSION. This is why, for most reliable M-60 performance, we got very good at replacing the extractor and ejector springs (and thoroughly cleaning out the appropriate recesses) AND all the little fiddly ones in the reed mechanism, on top of the really obvious ones like the return spring.
SAS’ BCG review in 2018; where he said the LMT enchanced BCG was his pick for the best BCG, most durable and most reliable. That’s what spiked the interest; in my opinion. Many people take what that guy says very seriously when he recommends something. And, he’s a big fan of LMT.
Supposed to be receiving my barrel in Jan still haven't been shipped,man y'all are backed uuuuuuppppppp I understand business and contracts so no worries I will wait til it arrives I know y'all doing the best y'all can. Thnx and keep making great riffles and parts.
Good vid and info thanks for taking the time. Owner of a old school LMT Defender 2000 lower with a 16in piston MRP upper. Would like to see some more info on your piston system. I can't out where it vents (lol but it works), gas ring longevity, buffer and spring set ups, etc. I am running a H2 buffer with a XP spring. Till next time!
I would LOVE to see LMT make their own version of a B&T APC223, FN SCAR, CZ Bren 2, or Robinson Arms XCR. I’m sure their take on one of those platforms would be SICK. Or at least a version of the SIG Spear/Virtus/Raptor. Side charging handle and all!! Especially with the quality LMT pushes out, I’m sure they’d knock it out the park.
The enhanced carrier has the straight part of the cam path lengthened, so the residual pressure is less when extraction occurs..This works great in the carbine length gas tube but not in the rifle length gas tube..This was one of the reasons the military turned it down, as it would have required two different carriers in the supply chain..The only modification I question is the ejection port top rail cut which will allow more ingress where the standard rail seals the carrier better.. The lengthened straight cut in the cam path was used by Jim Sullivan when they developed the Stoner 63..What was old is now new..
Thanks for doing this. Also, shout out to Aaron L. in commercial sales. I had a relatively small issue and he went above and beyond to take care of me.
I have used LMT E-BCGs (with std LMT bolts) in the following rigs for nearly a decade with Vltor A5 systems: 11.5" carbine gas (suppressed and un), 16" intermediate gas (Noveske/BRT length; suppressed and un), & 18" rifle gas. Superb function on all, especially when fouled with high round counts. Between the E-BCG and Vltor A5 system, the breadth of operation is just unsurpassed. My only Q: how does bolt life for your standard AR15 bolt (with rounded lug chamfers) compare to the amazing E-bolt?
I think people are also considering, the LMT bolt is virtually indestructible. And, what if a ban goes through and parts are hard to get? I need the most durable parts I can get now!
I can’t find anywhere that spells out the exact composition of the steel used by an arrestor hook. It does say, they are only good for 100 landing arrests.
Great presentation and really helpful info. Some ideas for future Qs: 1)why the barrel profile standard there is in the product line, 2)cryo vs chf (other than machine size why did LMT go cryo though you sort of covered here), 3)Speed bumps/receiver fitment, 4)MWS barrel line up (7.62 twist and why LW vs std, why the catalogue cut and what was the reasoning behind it beyond sales numbers or why those were what they were in LMT’s opinion), 5) what is the end user base breakdown for the commercial market from what LMT sees (e.g. precision, 3 gun, other gamers, hunters, etc.), 6) more of a defense question, but where does LMT see innovation in the market going in light of the NGSW program and international interest in large frame ARs, and 7) any cool past projects you can show us that LMT abandoned?
@@lmtdefense3927 Joe’s been doing a great job on answering most of these over the webcasts and these have been must attends for me. Still some in here to work in. Will be asking some of these and some MRGG questions on the next one as they fit in. Have to work some spec war clone questions in, mainly so everyone else will be poorer and I can go after the LMT products I love. Thanks for reaching out to your commercial base in such a big way!
LMT 10.5 uppers were the ORIGINAL suppliers of Mk18 CQBR to the Navy. Not Colt. Colt later sued, then became the main supplier. LMT is the only 10.5 upper I know of that is gassed PROPERLY (0.070) gas port. Which works perfectly with a suppressor. Unlike a DD 10.3, which is over gassed, (0.082) and way over gassed with a can.
i have the UK civilian legal sharpshooter rifle - straight pull - best AR rifle i fired , smooth and fast . I take you sill build UK straight pull barrels ?
How is your staffing for machinists/programmers? Is this a good field to get into right now? I am Super motivated to get into this filed. Fascinating stuff. Thank you for all your R/D and work in the field to help us have stuff like this.
I'm not sure how not putting FA carriers in the guns is covering your ass? It's not a machine gun because it has an auto carrier. Law enforcement are also subject to NFA , so letting them get the correct carrier is no different in any way than selling them commercially. It just doesn't seem to make sense to me but is what it is I guess. Another part for me to spend more money on! Still love the product, but that should change. Probably be easier on production to just have to make 1 carrier too.
Why do you need a full-auto carrier? You only have access to semi-auto. That's like wanting a Lamborghini because you can do 200mph even though the speed limit almost everywhere is a max of 70mph.
@@sackychin6267 I have tax stamps. Do you? I’m simply smart enough to realize that a Honda Civic is all I need; I don’t have a racetrack. My point is that hardware needs to match reality. I say the same thing about forward assists. They aren’t necessary and serve no function. If you want to alter or abolish the NFA, then we have a need for full auto carriers. Until then...
@@johngalt234 Full-auto BCGs have more mass than semi-auto BCGs which increases the locking time when firing. If you are going to be a FUDD at least get your facts straight.
@@ericanderson524 Question: does a semi-auto firearm need more dwell time to be reliable? No. It is important for full-auto weapons so that way the brass casing has time to constrict from both firing and the added heat from the barrel.
Joe, I had my own Q&A the same night you had this! I am on your Facebook group.
Love SAS
SAS is a great wealth industry knowledge, own and have already read everything he puts out including technical manuals

LMT is the best! That’s all I’ve got to say about that.
I bought one last month when titandefense got them in stock. I just ordered one more today for a different upper. I really like it. Great item.
Love me some LMT enhanced bcg’s and the receiver extensions/buffer tubes. Best you can get
I was impressed with your product when my QCA LEO buddy showed me his LMT .308. He keeps threatening to bring me out there sometime.
Nice work Joe. Looking forward to more of these.

interesting thanks
Take away - Run enhanced bolts n carriers on carbine length gas system ARs, especially with hot 5.56 hand loads or M855A1
Can you guys produce a video on the proper maintenance of your gas piston uppers?
It would be a VERY short video.
this video was made 2 years ago, the same as my LMT Enhanced BCG order, I still haven't received it from them to date.
The unicorn BCG
70K on an enhanced bolt is quite impressive.
We are still waiting for it to break!
My Daniel defense BCG is better. I had 600 rounds before the gas key started leaking. 😂😂😂
I can’t find anywhere that spells out the exact composition of the steel used by an arrestor hook. It does say, they are only good for 100 landing arrests.
It may or may not be Aermet steel. And, bringing a 50,000lb jet to a standstill 100x seems like honest work to me. ;)

Is your enhanced BCG individually tested? (Hp & mpi)
Does the 308 enhanced work in DPMS pattern builds?
Does the mystery metal rhyme with Inconel?
Will I have any issues if I run a lmt bolt in a JP?

Why do they say not to use the enhanced BCG on their 10.5 uppers?
Last I checked DD was using a .070 on their 10.3

Please make more 11.5 barrels in 5.56. 🙏
Nix that. Waiting for your new 12” midlength barrel. 😂
Running an enhanced bcg in my 300blk with 8.25” barrel and runs flawless
Can we just come in if we promise not to touch anything?
No, we know how that will end, lol
I thought the delay will let more gasses to escape out the front?🧠🤯🔫
Just got an email from Brownell’s, stating my e-bcg back order was cancelled, because they will no longer carry them.
Ron this is unfortunate to hear. Can you send an email to sales@lmtdefense.com with a confirmation of when you placed your back order?

Can’t speed for LMT but manufacturing has been pretty strong in my sector and there is always jobs for machinist/programmers.

Completely dodged the question with your answer on why you use semi auto carriers in your rifles. LMT’s reminding us that we’re subjects.
