Ideal cylinder compression?

Actually, it sees regular duty at ACTS matches. I use the damn thing more than my wife!

The rifle has a 16" pencil barrel, chrome lined, and a 1/9" twist. I built it for the wife to be as light weight as possible. Built it on a Sun Devil billet lower and a J&T upper kit with chromed bolt and carrier. Otherwise it is really just a basic AR. Put a Tac-Latch on it, M4 butt stock, CAR hand guards, A2 grip, P-mags, A1 birdcage FH, and a fakepoint.

That's a nice looking rig! How do you like the fakepoint? As for the 1/9 barrel, you're better off using the 55gr bullets although 1/9 should stabilize 62gr fairly well.

Here's a pic of the rifles I use the most:
From left to right, top to bottom: M1A in a Sage EBR stock; Armalite SASS; Savage 10PC; a WASR-10 that I did a lot of work too; Bushmaster ACR with EOTech 553; BCM M4 on Rainier lower; Olympic M4.

The M4 with a BCM 14.5" upper on a Rainier lower is my favorite rifle in 5.56. I take that thing everywhere. Reminds me a bit of what I was issued in the service except I take care of this one much better. I used to have an ACOG TA33-ECOS mounted but sold it. Couldn't stomach the idea of spending $1700 on a single optic. Right now it's configured with an EOTech 553 in flat dark earth, a Hogue grip, VLTOR stock, Midwest Industries drop-in handguards, BCM BCG, 14.5" medium contour hammer forged 1/7 chrome-lined barrel and AAC Blackout pinned on, and Armalite match trigger.

I need a bigger safe... :supz:

Are we gonna get in trouble for really going OT now?? :boogie:

Not at all, the last page and a half of post is directly related to compression specs and expected engine life. :whistle:
