This is the reason why I am a proponent of buying from companies which sell products of a known quality which I always list. They are known for selling products that are made to proper specs which have undergone the proper quality testing. For bolts that means they are individually tested and not batch tested. The cost difference is so small it really doesn't make sense to cut corners and buy any of the cheaper "mystery" parts on the market....even for a weekend plinker.

Some of the companies, even ones we talk about this site all the time, buy bulk mystery parts and pass them on to the buyer, maybe even one you listed....

Buying an AR15 from these companies is like a box of chocolates, you never know what you're going to get. I like reputable companies and I'll spend a few more dollars to ensure I'm taken care of, if the issue arises.

Getting kinda hard to find any from anyone but I prefer and own BCM, LMT, DD, Spikes. Noveske is GTG and the MPI/HP tested PSA BCG's have worked great in the rifles I have built with them.

Thanks Wahoo.

One question if you can answer...Do you know who makes the BCG for PSA?? I know FN makes their barrels; didn't know if someone might know about the BCG.

The only reason it's called a full auto bolt is because it is heavier than a semi auto version, thus slowing the rate of fire in a fully automatic rifle. BCG has nothing to do with FCG.
Wrong, it is needed to trip the auto sear to make a full auto work.
With out a full auto bolt carrier it will to trip the sear and fire full auto.
So it is needed to make the FCG work.

I really don't know what the heck is going on with all the companies, I have got PSA stuff that is marked MPI, some not marked and other with a lower case white text mpi.
I think it is all low bid or who ever has the parts.
Also the milling marks and tooling is not the same, even on the PSA uppers, they are being milled by different companies.
Also picked up a DD BCG, does not look the same as one I got several weeks back, in a little different tube, Carrier is marked DD, bolt not marked, older one was MPI and I thing something else also.....

They work so I don't care but when you get several of the same brand, like the 300 blackout cmmg 2 with FA BCG and one with SA.... WTF, all ordered from Midway over a few months time.
