Seeing “MIL-SPEC” as just the starting point, we set out to ensure the best options are available for our demanding customers. Improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphated bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. Extractors are S7 Tool Steel. From there, the extractor is sprung using the spring, o-ring, and silicone insert.

AVCMUSN –
Bought as a replacement for a suspected bad 7.62×39 bolt I had in place. It made an immediate improvement on the extraction issues I was having. The extractor was good on the old one, but regardless of the upgrades I tried to improve my old one, it was only working intermittently at best. I still have extraction issues every once a in a while, but I believe it to be the chamber needing to be polished. It is shooting cheap steel cases ammo much better now. I only gave 4 stars due to the short time and round count I have with it.
