Our Made in the USA handguards, the VLCN, HWK, RPTR, and VYPR, are designed with vent channels along the length of the handguard which serve to increase airflow around the barrel. With a rifle length barrel you’ll want to choose a handguard in this size range because it will ensure that the muzzle device extends past the end of your rail.Ī main role of the AR-15 handguard is to increase your shooting accuracy by minimizing barrel warp.Īt STNGR, we understand the needs of shooters and have developed a line of free float handguards that specifically meet these needs.

In the industry, this length range is known as a rifle length. Still love the weapon and will continue to buy BCM.If you have a 12.5” - 16” length barrel, then you need a handguard length of 12”, 13” or 13.5” lengths. Ordered replacement rings and will install. If the rings are good the bolt group should not collapse under it' s own weight. However, during a cleaning yesterday I checked the gas rings by standing the bolt carrier group on end with the bolt extended. Absolutely no functioning issues since then. Turned it mostly closed and opened until weapon cycled reliably (plus a quarter turn more). Ended up installing an adjustable gas block. Tried heavier buffers all the way up to an H3 with same issue. Would lose grip of the fired case part way thru the extraction cycle and then the bolt would travel back forward trying to shove the spent case and a live round into the chamber. When I first assembled it to my BCM lower it was seriously overgassed. I' ve had (2) issues with this upper.

Always have gone to BCM because you' re not spending money on bling, just seriously quality equipment. Posted by Monte J Stanloski on Jan 14th 2020
