First up is a hobby built shooter, pseudo Mk12 Mod 0 style upper. PRI upper, bolt, Gen III float tube, top rail (the version that bolts directly to the tube, not the rail like a true SPR rail) and front sight/gas block. OPS Inc collar and brake. RRA 1:8 stainless barrel.
Mods and other notes: Upper finished in Brownells moly/teflon spray & bake Dark Earth. A few rubs and nicks from scope mounts/rings and then storing and shifting in the cabinet. Could all be touched up easily with the above. PRI top rail had the rear tab removed so any rear sight could be mounted. The float tube locking collar has a boogered up spur on it from tightening it up during the build. The top rail covers it mostly, but, it's still there. The OPS Inc collar was not so precision dremeled to fit so if you have a real deal Mk12 can then you better check it before mounting and firing it. It rubbed up the barrel a bit too in fitting it on there. It was all about the looks so it didn't matter to me. Adco chopped down the 20" to 18" and then bead blasted it. The barrel has about 500rds total through it, all brass cased. All in all, a pretty solid shooter. $625 shipped to you.
And next is a basically new Adco built Mk12 Mod 1 upper. Diemaco upper (I think) and KAC rail. I believe they use WOA barrels. OPS Inc brake and collar as fit by Adco's shop. Test fired at Adco and that's it. Has bolt and standard charging handle as shown. Finished in Brownells moly/teflon spray & bake. A few marks from scope mounts and rings. $1000 shipped to you.
Clearing out the cabinet to pay bills so no trade offers please. Of course items will be shipped insured with tracking information sent to you. CONUS shipping only. No overseas at all, please don't ask, and if you feel I'll make an exception especially for you let me say, "No thank you" now.
