Are you sure you wish to do this?
Got these new from Palmetto late last year. Decided to go another route. Never fired, Assembled onto upper then placed in safe. PP F&F, Venmo, Cash app. 2 1 x PSA Premium Dissipator. CHF Mid-length Gas. 1/7 Twist. Shipped where legal. If Palmetto or AIM won't ship to you, then neither will I. Also have a Del-ton Dissipator HBAR 1/9 upper with 20 rounds on it I'd let go for 300.
