The M4-profile 4150 CMV barrel in this rifle kit provides MOA accuracy, thanks to a new .223 Wylde chamber that better handles .223 Remington and 5.56 NATO. Now you can safely shoot both. In addition, we went with a free-float, lightweight M-Lok handguard that provides plenty of rail estate for that bipod, tac-light, front BUIS, and other kit. All other standards come mil-spec in this rifle kit: An M4 buttstock pairs up with a Carbine buffer, M16 BCG (works with the side-charging handle with no modifications) and mil-spec trigger, housed inside a 7075-T6 forged flattop upper.
