crosselot Posted December 16, 2017 Share Posted December 16, 2017 Need advice on which low mass bcg to use. It will be going in an Armalite 13.5in barrel chambered in .223 with the adjustable gas block and jp silent capture spring. I have been looking at the JP and Iron City Rifle Works bcg.

Jmoreno88 Posted December 16, 2017 Share Posted December 16, 2017 Iron city is good along with JP. I run a voodoo and have run an aim surplus beforeSent from my SM-G955U using Tapatalk Link to comment Share on other sites More sharing options...

HRider Posted December 23, 2017 Share Posted December 23, 2017 I only have personal experience with JP, so I really can't make a fair recommendation. I do know that when parts weigh less and have the same amount of force applied to them, their velocity increases. JP has engineered a system, with the low mass carrier, buffer and their action spring, that works well in conjunction with adjustable gas. JP increased the bearing surfaces of their carrier because of the increase in carrier speed. I would recommend using a titanium firing pin due to increased carrier speed to lessen the possibility of a slam fire, no matter whose carrier you decide to use. I have two JP rifles with JP LMOS, one has many thousand rounds through it, neither rifle show any signs of fatigue on any of the reciprocating parts.

dogtired Posted January 1, 2018 Share Posted January 1, 2018 I dropped the AIM low mass in my rifle and it works great. Best price point out there too. Link to comment Share on other sites More sharing options...
blacklab Posted January 9, 2018 Share Posted January 9, 2018 +1 for the AIM low mass. I have about 4k on mine, runs great. Link to comment Share on other sites More sharing options...
coolcw1987 Posted January 9, 2018 Share Posted January 9, 2018 If you want the best value I would say Aim BCG. If you want the lightest you'll need the Whiskey Arms. Link to comment Share on other sites More sharing options...
Pyre602 Posted January 10, 2018 Share Posted January 10, 2018 I have the AIM BCG also, and it's worked great. The only issue I've had was it, was the gas key came loose after about 2000 rounds. The gas key wasn't staked correctly. After getting it repaired, it's run flawlessly Link to comment Share on other sites More sharing options...
Vespid_Wasp Posted January 13, 2018 Share Posted January 13, 2018 JP was the first. I think JP is the best. I bought a JP for my 3-gun rifle back before there were all these other options. I needed another carrier to go in a monolithic upper where I don't want to the carrier to chew up an expensive receiver. I went with the JP again because of the increased bearing surface, even with the multitude of less expensive options on the market today. I would be amazed if you can wear out a QPQ JP carrier. Plus I have never seen Aim Surplus sponsor a match or put stuff on a prize table at a match I have been to. Link to comment Share on other sites More sharing options...

Screaminyz Posted January 15, 2018 Share Posted January 15, 2018 Any know if the Right to Bear lightweight BCGs are any good, they are priced like the AIM and look to be made by Rubber City Armory. They also have a no bs guarantee. What’s AIMs warranty on theirs? I’m trying to decide on one myself. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
dogtired Posted January 22, 2018 Share Posted January 22, 2018 AIM is $100 bucks. If it breaks I will buy another. Thats my perceived warranty. Link to comment Share on other sites More sharing options...
TonytheTiger Posted January 23, 2018 Share Posted January 23, 2018 Had the gas key come loose on the AIM carrier recently. Something I'll add to my preflight check from now on. Link to comment Share on other sites More sharing options...
Screaminyz Posted January 24, 2018 Share Posted January 24, 2018 Dogtired no need to buy another one. I just emailed AIM the other day about their lightweight BCGs and they said they are lifetime warranty. I was going to grab one myself but took the chance on a used Iron City BCG in the classifieds.

spininfirec Posted February 9, 2018 Share Posted February 9, 2018 I own JP low mass and JP ultra low mass. I absolutely lover them and would not build a race gun with out them. I go with the ultra low mass for really trying to dial down the gas and lower recoil. I've ran them since the day they came out, no problems. I dont trust the others, Ive seen a few break and a few dont look like they are designed to last. I dont own a jp gun but I run a lot of there components. a very well trusted company in the comp world. Link to comment Share on other sites More sharing options...

Joeg26er Posted May 1, 2018 Share Posted May 1, 2018 Question for those running the low mass Whiskey Arms low mass bcg. What buffer, spring, gas system are you running? I am having some teething / set up issues with my low mass adjustable carrier 2A bcg. Using carbine buffer with weights removed, red extra power spring and dialing back to lock up on empty mag but still getting occasional mis-feed. The live round after firing about 2 to 3 consecutive double taps jams tip up with the bolt jammed into the casing midsection dialing gas down to single shot mode and then dialing up to mag lock back...
