Description

Currently selling as a package only. Don’t want to split up and be left with more left over parts. The only possible option would be for me to keep optics with mounts, and light. But… will wait a bit before I do that. IF THIS IS POSTED, ITS AVAILABLE… no need to ask.

Upper performs flawlessly and has been tuned to have the softest recoil you’ve probably felt on a 10.5” rifle. It’s insane. Has probably 800 rds through it. Laser engraving was done aftermarket and not original. Paint is standard Kelton and has been stored in a rifle bag in my vehicle trunk lock box for about 2 years, but rarely ever taken out. Might have some boxes for optics only.

Again… NOT parting it, if you want an item, buy it, part it, and resell on your own time please. Save the messages about specific items, the answer will be “no thanks”.

The build:
-Colt cage code upper
-Gemtech suppressor BCG (discontinued)
-Colt FBI barrel dimpled by Marvin Pitts
-SF 4 prong flash hider
-KAC URX II mid length (small section cut under FSP to fit gas block) obviously discontinued)
-Wilson combat adjustable straight gas tube and adjustable carbon cutter gas block (discontinued)
-Geissele airborne CH
-KAC USMC adjustable rear sight (not pictured but included)
-KAC rail panels and magpul ladder
-Larue scout mount
-modlite OKW tan head, black body, black DS00 and a SF SR07 trimmed and zip tied (trimmed because it was run between 9’oclock and 12’oclock rails when I had a laser mounted.
-tango down stubby
-Aimpoint M4s with kill flash
-Aimpoint 3x
-Unity riser on optic
-Unity mount on magnifier

Upper was built properly per USN Crane specs and procedures with appropriate tools and everything was tourqed properly and locktite applied where called for per MFG specs.

If you were to price this out to retail prices, it’s over $4,000.00 worth of stuff. Trades maybe entertained at that price range, and mainly would be for bolt guns, 2011’s, or other KAC items.
