AR 7.62x39 Melonite QPQ Bolt Assembly and Enhanced Firing Pin Combo

A: Yes we grab the bolts from the same bin. We just give a little break in price as it's a combo going in the same bag.

A: There is no issues with brass ammo; however, if you are having jamming issues we would need to go over additional questions to properly see what is going on. Please call us at 386.410.5162 and we will be happy to get you over to tech support, if we don't answer please leave us a message so we can call you back.

A: 7.62x39 is considered Type I bolt assembly.

A: Yes all our bolt assemblies and BCG are full auto rated.

A: An enhanced firing pin allows for further protrusion to set off steel case harder primers in this caliber.

A: It should work with no issues as long as the AR-15 7.62x39 takes mil-spec parts.

A: QPQ stands for Quench-Polish-Quench, which describes a sequence of secondary steps following the liquid nitriding step. This finishing process provides a surface condition that protects against corrosion and wears superior to hard chrome or nickel plating.

A: FTF and FTE can be due to other issues than a bolt assembly, but as for extractors we do try to leave some meat in some critical areas however you will still have extractors that fail due this caliber and how much meat you do have to remove. If you are having a high premature failure on extractors it may be your overgasses (on this caliber you should have your extraction pattern around the 4 o'clock position) also stick with Wolf Ammunition if wanting to run steel, Tula gets stuck in the chambers and one puts undue stress on the extractors trying to extract. We have noticed Tula casings do not shrink like you see in Wolf casings.

A: I'm unsure what caliber your Stag Arms AR15 is; however, If your Stag Arms is a 5.56 then no you would need a new barrel, bolt, enhanced firing pin and magazine along with a 30 caliber muzzle device. If you have a Stag Arms AR15 7.62x39 rifle and have light strike issues you only need a 7.62x39 Enhanced Firing Pin as you should have a 7.62x39 bolt assembly in it already.

A: Yes you should have no issues.
