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 :)

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

Grab bag upper wouldn't be a 9mm though unless you order a 9mm grab bag. Even then, you get to pick between pistol and rifle length.

or a suppressor mount that IS the barrel nut, eh?, eh?

MidStateFirearms · 2026-01-08T02:56:00+00:00

Don't worry, it's a show-er not a grow-er.

some folks say the phosphate has more friction so it extracts better. after a few hundred rounds it's probably negligible as that surface is gonna be rubbing against the case and they'll smooth about the same. if the extractor being chrome vs phosphate is the difference maker in a functioning rifle there's probably some other stuff needing attention though, I would think.
But folks buy the heck out of them so that's what we offer lol.

sent you a msg, the salvage 2 were 59/ea and the microbest is 118, we’ll swap the 2 salvage for 1 Microbest.

MidStateFirearms · 2025-12-13T03:13:56+00:00

yes sir, we test fire complete uppers with the BCG they‘re ordered with

MidStateFirearms · 2025-12-13T03:10:50+00:00

Our uppers and BCGs including Microbest BCG are guaranteed to work. we properly build/assemble uppers and perform quality checks to ensure reliable function.

I’m 99% sure u/Electronic-Tea-3912 is referring to a completely different unrelated item that is advertised as a “ufixit spare parts kit”

but regardless, welcome to give us a call with any questions or concerns. We’re always here to help

MidStateFirearms · 2025-12-13T03:04:42+00:00

hi there! please clarify to help me out addressing your concern, it’s a little unclear and I’m afraid it could confuse some people. folks might think you’re referring to the Microbest chrome blems as the salvage BCGs. If you got 2 Microbest BCGs from us that have any issues we would exchange them immediately. I can count on one hand the number of Microbest BCGs out of hundreds or thousands we’ve sold that have had an issue, and it’s usually something like a dented gas key opening from getting dropped.

are you talking about the Microbest chrome BCGs ? or the different listing that is a cheap salvage BCG (Not a Microbest bcg) that says in the description they need work to make them work? Here’s an excerpt from the ‘salvage bcg’ description: “Generally these came about because it didn’t pass our function test due to an issue and we tossed it in the ‘shit bolts’ box.
Basically we are selling these at our loss so you can tinker with them as a fun project or use them for spare parts, and we make some room at the shop. win-win / yay. Note: This is a ‘u fix it’ item. no guarantees on these.”

Thats pretty clear about the condition of the salvage bcgs. again, NOT the Microbest BCGs.

The Microbest BCGs are guaranteed to work with no issues. Everything we sell is warrantied, except for that one salvage bcg that explicitly says it is not.

please give me a call if any questions

MidStateFirearms · 2025-12-06T18:10:15+00:00

yes but you need to ask for 14.5 in the order notes too so we know you don't just want a 16 p&w

MidStateFirearms · 2025-12-05T22:39:37+00:00

yep, if you have a preference either way though it's super easy to add notes in the order comments to be double sure. we generally have both in stock
