Sabre Defense (unmarked) 14.5" midlength upper receiver half with M4 flat top upper receiver assembly, low profile gas block, USGI barrel nut, gas tube, BCM MOD4 Gunfighter and BCM A2X flash hider (pre-drilled for pinning). All parts are new and unfired (but there are some minor handling marks). Barrel has been dimpled for the gas block but I have not Loc-tited the set screws.
Barrel is 1/7 twist, chrome lined 4150 CMV.
This is a good set up if you are looking at building a carbine with a rail as most of the work is done.
Asking 335.00 which includes USPS shipping. Prefer Paypal as a gift or USPS money order.
