I have a large hole, preban, grey, Colt R6551 upper for sale. This has the chrome-lined 1/7 20" government profile barrel, A2 flash hider, shaved bayo lug. The upper is very low mileage, and is an accurate shooter. Condition is ~95%. A small ding on the washer near flash hider, very light scratch on barrel near ding. NO BOLT/CARRIER/CHARGING HANDLE included.
Payment by US postal money order. $350 shipped.
Editted to add possible trades: I am looking for a plate carrier rig. Wasatch, Blackhawk Recon Commando, etc. OD green preferred...
Also consider: Aimpoint, Glock 17/19, Leupold MR/T, M1A mags, etc.
