This a USED Bushmaster 14.5 inch heavy barrel upper with a Knights Armaments Rail Interface System (RIS). It's a complete upper receiver with bolt, bolt carrier and firing pin. The muzzle is threaded so it will accept any host of muzzle brakes or compensators. If you live in a state where the minimum barrel length is 16 inches then you must permanently attach a muzzle brake or compensator to the end of this upper bringing it to the legal length. The barrel has had less than 500 rounds put through it. S&H will be via UPS so I will advise potential buyer of shipping charges depending on where they live. I will only ship to US addresses only, no foreign sales or PO boxes. I accept PayPal or money orders, sorry no personal checks. If you use PayPal please make sure it is a confirmed address. The sooner I receive funds the sooner you receive this upper. It is the buyers responsibility to check all local and state laws before purchasing this upper. Thank you and have a great day.
