I'm getting out of the AR pattern x39 stuff.

Mini upper that was shaved by tactaylor. 10" heavy 7.62x39 barrel with RA single port brake(needs shims or crush washer). Type 2 gas block, tube and op rod. You can use your type 1 or type 2 carrier and bolt in this along with. I've got approximately 80rds of suppressed shooting on it. Will include one poly rail section and backer plate. It's secure enough for a light or grip but I wouldn't trust it for a laser/optic.

Let me know if you've got any questions. I've got a type 1 carrier and recoil assy I could add.

As pictured, $660 shipped.
