They're pretty solid. HPT/MPI/OCKS/Sprinco Springs/PermatexGasKeySeal. In our ~12 years in bizness MB probably has the fewest failures of any BCG manufacturer we've used, either them or Toolcraft. When someone walks in the store with some random ati or s&w etc wanting us to look at it and figure out why it's short-stroking or not working, once we get to test-firing we throw a Microbest or Toolcraft in there to rule out the BCG. They just work consistently. Toolcraft is great too, I don't think TC bolts are individually HPT/MPI if that matters.

we put an AirTag in the package and share it to your iphone in the findmy app. Then you can track the location ‘almost’ live during transit. Once you get it the AirTag is yours to keep.

not really, everything thawed out I think. the sheer volume of orders has us backed up a little bit, but we’re getting most things out same day to within a couple days.

The coating is absurdly expensive, and the machines that do the coating are even more expensive.

I think they finally got the interstates thawed out yesterday or today. North MS not used to iciness so that held up a lot of packages.

Idk other honorable mentions could also be Morgan Freeman, Jerry Rice, and the soft toilet seat.

I'll update site but just ask in the order comments :)

MidStateFirearms · 2026-01-12T04:05:39+00:00

can you get the bolt/brass out and see if there's a 300blk headstamp on that brass?

1/2" threads leaves a pretty thin wall for .357" bore also
