Proof Reseaerch AR-type barrels are designed to be used with standard, ‘full’ mass bolt carrier groups, standard mass buffers and standard rate recoil springs to ensure the best reliability and accuracy. All components of the buffer system must match, i.e. do not mix AR-10 and AR-15, or carbine and rifle length parts. Light-weight or variable-weight bolt carriers are not recommended.
1 Proof Research builds AR barrels with standard DPMS™-compatible barrel extensions and gas system lengths. A select number of AR-10 barrels are available with deep feed barrel extensions for compatibility with Armalite, Falkor, F-1 and others. Please check with the manufacturer of your rifle platform to see if these configurations are compatible.
2Custom length gas tube included.
