    I'm really considering getting the 11.5 for my build and I already have an A5H1, would it still run well with that?

    My 11.5 CQB barrel doesn't have any issues with the A5H2 and BCM rifle spring, but I usually am running 5.56 or stronger 223 ammo. It also passes lockback tests with some of the weaker ammo. Sample of one and all...

    Good to know, thanks for the timely reply. I have some weights I can throw in the buffer as well if needed.

    My friend chrono'd his and didn't see much if any difference between his 11.5 BRT barrel and another 11.5 barrel he had.

    So I finally got out to the range to test the Spring Co White hot spring in my 16 MPR. I also was testing a Spring Co White in a BRT gas'd PSA 10.5.

    With the 16 MPR + White Hot: I got lock back on 4/5 wolf steel cased. Locked back fine on the M855 and 556 pressure 55gr HPBT frontier. The gun actually felt really good with this gas and spring combo and I am looking forward to shooting it in future matches.

    The 10.5 + white: Had lock back on 5/5 wolf steel and locked back every time with 55gr 556 frontier. Feels really good to shoot.

    I'll report back if I have any reliability issues but first impressions are really strong of the spring co buffer and extractor springs.

    Will a 10” rail completely cover the GB on the 12.5”?

    I don’t know enough to say it’s “better” than anything, but the 11.5 EXC suppressed is awesome. Mag still got dirty, but the sight didn’t jump around much and the sound was outstanding for supersonic rounds in an indoor range. More accurate than me.

    Clint,

    Will you have any 12.5" or 14.5" in stock anytime soon?

    Also, with an A5H2 buffer, will the SpringCo Green run well unsuppressed?
