Mid-length ejection angle

Got my upper back from Criterion.

They said the two BCGs I was using were bad. At least the bolts were. They gave me a free BCM bolt. Gas block, ports, etc was all fine. They said Sharp's BCgs are trash.

Yeah that doesn’t surprise me with the BCGs you posted. Awesome of them to just give you a free $80 bolt.

The quality of their product will probably vary depending on the specs requested by their OEM customers. I've chased the problem of bad BCGs with both a S&W and DSA BCG. Criterion is an excellent company, hope that solves the issue for you. Let us know how the next range trip goes.

I'm having difficulty seeing how the bolt was the problem. Could someone explain, please?

[Wow]

they said the bolts were out of spec causing inconsistent chamber pressures. They said it was cycling with all their ammo (millsurp, blackhills, etc). I doubt they tried the A5-H2 buffer and system though. Mine was working on the carbine setup before I even sent it in.

Interesting. I'm eager to hear how it does with A5 now that you've got it back.

What spring are you using?

Criterion has made public statements about use with the A5 so I wouldn't be entirely surprised if they tested it if you told them about your config.

What's the gist of Criterion's statements on the A5?

Sprinco green.

What is this statement. I talked to them over the phone and the didn't mention anything to me. I told them I was using the A5 system.

I'll go shooting again in a few weeks hopefully. I just gotta remember to bring my A5-H2 buffer. I am currently using the A5-H0 buffer with no issues.
