Q: Good afternoon, I bought both the 11.5 and 16" x39 barrels as well as an x39 bolt. This being my first DIY AR, I'm using a Stag Arms receiver set for this build. I want to see if there are any issues with headspacing I should concern myself with once assembled? Also, any mitigation steps recommended.
A: There should be no issues with headspacing, but we do recommend all bolts and barrels regardless of the caliber to be headspaced by the end user.
Q: Wanted to provide the build specs:
BRA barrels (1-16" and 1-11.5" upper) BRA enhanced firing pin, Superlative Arms Gas Piston system (mid length and carbine) SA's ION bonded bolt carrier and a POF roller cam pin, Armasight Stealth buffer, and a strike venom muzzle device, POF enhanced buffer tube, MFT Minimalist and a UTG Pro 15" SS m-lok and a Primary Arms ACSS Scope 1-6x
Thanks for your expertise and input
A: Using an SA piston setup with a 7.62x39 mid-length gas setup will never run reliably and we don't see it running reliably on the 11.5" 7.62x39 setup either due to the length of the barrel and considering dwell time, etc.
Q: Is the finish glossy as the picture shows? Or is it a matte finish?
A: Melonite finish is not glossy, that glossy look in the picture is from oils and lighting. Melonite is more of a slight sheen but not matte like a phosphate coating.
Q: Which gas length for 7.62x39 with 16" barrel and 6 position carbine extension/carbine buffer?
A: Either a carbine or a mid-length will work fine with this setup.
Q: Are these barrels HPT/MPI?
Q: Does this barrel require a true
Also do you typically have this barrel in stock or does it sell out often?
A: Yes, the 7.62x39 barrels require a true .125" bolt.
Q: Is this barrel chambered to SAAMI or CIP spec?
A: Barrel is chambered to SAAMI spec.
Q: is the .750 gas port section of the barrel long enough to mount an A2 style FSB?
and do you offer a drill and pin service for a fee, when purchased?
A: Yes, the length of the gas block journal is approximately 2" and long enough to mount an A2 style FSB. We do not offer a drill/pin service, that would have to be done by your local gunsmith.
Q: Is this barrel in Stock?
A: Yes, these barrels are in stock.
Q: Does this barrel come with dimples for a set screw type gas block?
A: No, the barrel does not come with dimples for set screws.
