I just purchased something similar, I ran across a CZ 527 synthetic American suppressor ready. It has a 16 1/2 in barrel and is threaded if you need it. It is about 5 1/2 lbs. Its a mini mauser action, controlled round feed and detachable box mag. I haven't shot it yet, so I can't comment on accuracy, but the CZ I have had have easily been moa to sub moa.

Enough already, just shoot it!
