16" 7.62x39 Black Rifle Arms Mid-Length 4150 Nitrided Barrel

A: No it's not, their system requires a much larger gas port and I'm not sure if you could get it running even then. You would need to call them for making their system work for this gas length in this caliber.

A: Yes, our barrels are concentric with bore.

A: No. We literally take them out when building demo rifles and just start shooting full auto through them. Never an issue and who has time for all that shoot a few, clean, shoot a few more clean.....we say let it rip!

A: I just put a few in stock. Our shelf was empty so went to the workshop where they do the upper builds to pick up a few and we have more at nitride due back soon.

A: A mid-length gas system will help in reduce recoil over the carbine gas system. If one was doing a build with a picatinny gas block and not a low profile gas block a mid-length gas system would allow for a longer handguard, as well.

A: Yes it has a recessed crown.

A: This particular barre is not dimpled.

A: No it is not dimpled.

A: Gas Port Size for the 7.62x39 Mid Length barrel is .104"

A: If you have a traditional A2 front sight that needs to be pin and welded then no our barrel is not a good fit. If it's one like a JP Enterprises JPGS-2FS then it should be a good fit and shouldn't need any modifications.
