Equipment Exchange

For sale is a used upper I built out with a Surefire closed tine flash hider (CTN) which was used prior to this, Criterion CORE 12.5" barrel, SLR Rifelworks .625 gas block (staked set screws), BCM gas tube and factory blem upper (waves in ano on left side and pitting under the ano above the port door) and Ripcord Industries factory blem LDR-1 11.75". Its blem is one rough edge in a couple spots. I'll add more pictures in the comments. Assembly was done on proper fixtures to manufacturer spec with proper grease/thread locker where appropriate.

It has around 200-250 rounds on it, mostly suppressed with a slow rate of fire to test on a chrono. It was excellent for accuracy, which you'd expect from Criterion.

I can do discreet PPFF, Venmo, Zelle or Apple Pay. USPS MO or personal checks from members with established feedback ok too. Thanks for looking.
