I was going to put this on Gunbroker, but I'll put it up here first to see if there's any interest. It has had 90-100 rounds through it.
All parts are Franklin Armory. Here's what I have; I'd like to sell it all altogether for $275 shipped/paypal'd in CONUS.
20" barrel with rifle length gas system, 1/24 twist, barrel threads are 11/16-24
Railed gas block & rifle length gas tube
.450BM bolt
