Geniune Colt with C stamp. Used but in good shape. Gas key staked. Complete with everything. Possible trades - Ammo - 9mm, 223, 22lr may interest me. Powders or other reloading stuff as well. Have a cool gun? I may be up for adding cash on my end. Also have a slight interest in a another upper possibly a caliber other than 556 that works with a standard lower. $275 - I see very recent sold listings on gunbroker $375+ for the same thing. All offers, comments etc please PM.
