Clint U66 Posted December 12, 2018 Share Posted December 12, 2018 13 hours ago, TonytheTiger said: I assume you're using the JP aluminum carriers? What kind of lifespan are you seeing from them? I bought a couple when they started making them again a few years back. The two I have are both in similar setups and use the same ammo (14.5 with titan brakes, adjustable gas, and JP SCS). They are also setup for a 55 gr. bullet at 2700 fps. So far there are no signs of wear or fatigue. I'll also mention that you can tell a little difference in aluminum vs. steel carrier.......aluminum being a little better. Link to comment Share on other sites More sharing options...
TonytheTiger Posted December 12, 2018 Share Posted December 12, 2018 Good to know. I tried a cheap aluminum carrier earlier this year, liked the performance but it died fast. Now I'm trying to tell myself spending more money on one will buy some more life out of it. Link to comment Share on other sites More sharing options...

If you want something in between that may offer more longevity, you may try to seek out a BoomFab Titanium Carrier. Those worked really well and everyone that I know that has used them had good luck.

Darqusoull13 Posted December 13, 2018 Share Posted December 13, 2018 I'm a big fan of the JP LMOS carrier in both small and large frame AR's. I'm closing in on roughly 10k rounds on my first small frame LMOS steel carrier and it's held up extremely well. I really see minimal wear and all I really do to clean it is spray a little brake cleaner every now and again and keep adding Mobil 1. I have not had to adjust the factory tune and my rifle runs 77 gr reloads, 75 Hornady factory, 69 gr reloads, 55 gr Federal, 55 gr reloads and a couple other super fun loads all 100% and quite soft. I might be able to tune the recoil slightly less with 55's but being able to run any of that training / match ammo 100% is much more important to me than a sub 5% change in an already light recoil impulse.

MJC082581 Posted December 27, 2018 Share Posted December 27, 2018 (edited) JP and RCA are great. I actually just picked up a FailZero LW BCG on sale and am curious on how that will perform. I’ve got it set up with a Tubbs flat wire spring, Taccom ULW buffers and an SLR block. Edited December 27, 2018 by MJC082581 Link to comment Share on other sites More sharing options...
pcs352 Posted December 27, 2018 Share Posted December 27, 2018 Another very pleased JP owner here. JP has been doing it longer than most, supports the sport, and he understands the AR and it’s capabilities. It is a little more money but buy once cry once...

Elgin Posted December 29, 2018 Share Posted December 29, 2018 I had never tried a lightweight BCG before, so I picked up an aluminum one from Delta Team Tactical to give it a shot (https://www.deltateamtactical.com/3-Gun-Labs-Inc-LMB-AR-15-Aluminum-Lite-Weight-556-BCG-Pick-Blue-Or-Red-Color-Great-For-Lessening-Felt-Recoil-Competition-Shooting_p_8436.html). Also using an adjustable gas block I got from them, and an Armaspec SRS (Carbine) on a 16 inch barrel. Only about 500 rounds through it so far. No function issues, but the finish wears really quick. I like it for the price, but went with a Brownells for another build. Link to comment Share on other sites More sharing options...

I am seeing a little wear only where the bcg contacts the hammer. I took their advice and have kept it seriously lubricated. I think that has helped.

The exterior wear isn't the problem, having your gas rings ream out the bore is a big problem. Link to comment Share on other sites More sharing options...

I'm seeing it along the length of the bolt body, in a few places, and where the hammer rides on the bottom. I'll have to try lubing it up even more.

I couldn't find anything on the "3 Gun Labs" bolt, and didn't know about the Surmount Defense or Shooting Innovations versions when I was looking (still new to all this). Did a little digging with this new found knowledge, and found your 3000 round update on the one you had. I'll have to pull it apart and take a look at how it's doing. All in all, I don't regret giving it a shot. I was able to snag it for just under $100, so while a loss of money, it's not a huge one. After using a Brownells in another build, that will be the direction I go from now on. Link to comment Share on other sites More sharing options...

I have two of the 3gun labs BCG's an have run one on a 300BLK build and don't see any wear. Probably only have 150 rounds though... Link to comment Share on other sites More sharing options...
TonytheTiger Posted January 13, 2019 Share Posted January 13, 2019 @Elgin Yeah I got mine on sale also, it was a worthwhile experiment and I don't regret trying it out, I just wish it wouldn't have kicked the bucket in the middle of a major match. In hindsight I should've known better, in the month leading up to the match I kept having to turn the gas up to lock back. I ended up with the gas wide open and was still short stroking by the end of the match. @Joeg26er I attempted to get a picture but there's really nothing to see. Dropping a couple different bolts with fresh gas rings in it is like throwing a hot dog down a hallway. Barely hits the sides. Link to comment Share on other sites More sharing options...
AverageJoeShooting Posted March 3, 2019 Share Posted March 3, 2019 this post will probably get some hate but ive been using the brownells low mass BCG for like 100$ and it has functioned perfectly its around 8.2 ozs which isnt as light as some but is defiantly lighter than some of the other low mass systems i guess it would depend on your budget Link to comment Share on other sites More sharing options...

AverageJoeShooting Posted March 4, 2019 Share Posted March 4, 2019 They arnt terrible and i feel like at a certain point splitting ounces wont make you a better shooter. a 7 oz bcg vs an 8.2 oz one wont improve your shooting Link to comment Share on other sites More sharing options...

I've had very good luck with the AIM lw, but the brownell's are a bit nicer on the finish I think. I'd rather have JP and a sweet 911 of course!

WhiteDingo Posted March 18, 2019 Share Posted March 18, 2019 I have been running the Brownell's LW BCG (with an added adjustable gas key) and it has been great. Have the AIM LW carrier in another rifle, and I agree that the Brownell's is finished nicer/more visually appealing. Functionally I doubt there's a difference.

verla Posted July 2, 2019 Share Posted July 2, 2019 I have two JP SS low mass carriers that I have used for years- since they came out- and have been very happy with them. No issues or problems. Link to comment Share on other sites More sharing options...
verla Posted July 2, 2019 Share Posted July 2, 2019 However- I had a JP aluminum carrier that was fantastic but used it so much that I wore it out-i.e. the AR started short stroking and jamming since gas was escaping around the bolt where the carrier was worn-i.e. out of spec.

clw42 Posted July 2, 2019 Share Posted July 2, 2019 I recently bought this one and it seems to work pretty good. It didn't include the bolt but I had a few of those laying around anyway. I paid $65 shipped when I ordered it. Machining is nice, seems decent for the money. https://www.righttobear.com/RTB-AR15-Lightweight-Carrier-Black-Nitride-carr-p/sbn16-lw-co.htm Link to comment Share on other sites More sharing options...
verla Posted July 3, 2019 Share Posted July 3, 2019 thinking about how many rounds I put through the rifle with the aluminum JP carrier- some where around 8000 rounds maybe- it was some time ago. It was a fantastic carrier with very little recoil- had an adjustable gas block on the rifle- rifle length gas tube. These carriers are only for competition.

inertia Posted September 6, 2019 Share Posted September 6, 2019 I have been running the 2A titanium that has the aluminum tail. I also have 2A steel with alu tail and JP both steel and JP ALU. I have setup rifles with some of the others I picked up off prize tables. So far the 2A titanium is in the guns I run in competition. The weight is almost as low as all ALU ones but none of the wear problems I had with the JP aluminum both wearing the inside of my upper and the gas ring wear and needing to add more gas as it aged. My original one has over 10K on it with no need to add more gas yet and no abnormal upper wear. The finish on the carrier itself even looks really good still.

I know this is an older post, but - do you still have that worn out aluminum carrier? I've wondered about boring out and pressing a hardened steel sleeve into one of these for longer life, and I have the machine tools to do it. A worn out carrier like yours would be a good one to experiment with if you want to get rid of it. Link to comment Share on other sites More sharing options...
