A: Yes our bolt assemblies work with their Bolt Carrier, but their bolt assemblies have not been consistently machined properly so other mfg extractors hang up in the barrel extension. We had the opportunity to work with a customer with a BCA 7.62x39BCG and we know why extractors won't work (customer tried 5 other MFG companies extractor for this caliber and they all hung up in the barrel extension) so our customer had us change out BCA bolt assembly for one of ours.

A: It will fit any AR-15 mil-spec bolt carrier, including FailZero AR-15 bolt carrier.

A: Bolts are designed to work with mil-spec AR-15 barrel extension. Our bolts work with our barrels that have mil-spec barrel extension with 30 caliber feed ramps.

A: Our bolts are made from the beginning as 7.62x39 bolts. As stated in product's description: Machined completely in one operation; this eliminates tolerance and repeatability issues that arise from the multiple fixturing processes used by other manufacturers

A: While we do have more meat on our extractors we can't make any guarantees when the extractor or lugs will fail because other forces come into play such as gassing of the operating system and certain ammunition such as Tula or Red Army (the cases do not shrink properly and puts undue stress on the extractors and single wide barrel extensions have no support and will cause lugs to break. Also we are seeing a lot of melonited/nitrided barrel extensions lugs being deformed overtime and causing issues also. We have no control over these issues, but the way we do ourbarrels and the way we gas our uppers we have some demo rifles with over 5,000 rounds.

A: Our AR-15 7.62x39 bolt assemblies are for AR-15 7.62x39 rifles that utilizes AR-15 7.62x39 magazines. PSA KS47 utilizes AK magazines and due to this the bolt assemblies on PSA KS47 are machined for the AK magazines so they are designed differently and you can't utilize an AR-15 bolt assembly in a platform that utilizes AK magazines.

A: It's a complete bolt assembly minus the firing pin.

A: They are in stock now.

A: This is just for the bolt assembly and nothing else. It sounds like if you are looking for a bolt carrier group which is the bolt carrier, bolt assembly, cam pin, firing pin and retaining pin. We have BCG (bolt carrier groups) but those are out of stock, at the moment.
