Product Info for Spikes Tactical 300 Black Out 16in Forged Upper Receiver

You need a versatile upper for your rifle build, and this Star Forged Upper received both a Cold Hammer Forged Barrel and a Cold Hammer Forged Receiver, which combine to create an incredibly durable platform. Star Forge crafted each upper with cold hammer forging, and each one is coated in phosphate for enhanced resistance to corrosion and wear. On top of that, this upper comes with a .750 gas block seat and M4 feed ramps that assist your smooth-feeding operation. A free-floating rail and snag-free apertures make this upper a top choice for most shooters, and the forward assist adds an extra element of safety to this assembly. Tested and function checked, this upper is a great addition to your existing firearm, or you can save on a bottle and use this upper as part of a combo build. Either way, you get everything you need to create a highly functional platform with the Star Forged Upper Receiver, M4 Feed Ramps, and rails with plenty of room.image
