.308 Gas Piston Systems

Black Rifle Arms® .308 Piston Uppers vs .308 Piston Conversion
As of late, we have received a tremendous amount of inquiries relating to a .308 gas piston conversion, so we feel the need to address this topic. We tested a drop in .308 piston conversions; however, while things seemed to be working flawlessly for several months once we went full auto we noticed an issue, which under extremely extended use, would cause a malfunction. While this potentially would never be an issue for an average shooter, for us we want to only produce products we would trust our lives with and know there will never be a potential issue down the road. During this time Charles went back to his machines and machined a larger component for the piston system and put it back to testing; after 4 years of testing, we can absolutely say without a doubt it's flawless.

Due to the forces of this caliber, we do not trust a .308 drop-in gas piston conversion and will never offer a conversion in this caliber. Also, we get inquiries asking if we would modify an end user .308 upper receivers to accept our .308 gas piston system, and the short answer is no. Due to liability we will not modify any end user .308 uppers for use with our .308 gas piston system.

The other question we get is, "Are we going to incorporate our buffer technology into the .308 piston system?" The answer is, "YES, without a doubt!"
