Grey Ghost Precision AR-10 Heavy Receiver Set Features The Grey Ghost Precision AR-10 Heavy Receiver Set is precisely machined from 7075-T6 aluminum billet stock a material chosen for its strength and its ability to hold tight tolerances throughout the manufacturing process. This billet construction allows Grey Ghost Precision to incorporate features not possible with forged receivers giving builders a new level of customizability for their rifle project. A hard coat anodized finish protects both the upper and lower receivers from wear and corrosion ensuring the set holds up through years of range use and handling. Because this is a semi-automatic AR-10 pattern set it is compatible with a wide range of aftermarket .308 Win components letting builders mix and match their preferred parts. The lower receiver includes an ambidextrous bolt release as a standard feature giving left and right handed shooters equally fast control over the bolt without needing to reach across the receiver. A flared magwell speeds up magazine changes under time pressure while an integral trigger guard adds durability compared to a removable pinned guard. This set ships without a port door forward assist or small parts so builders should plan to source these separately to complete the rifle. Paired with an M-LOK compatible handguard accessory the Grey Ghost Precision AR-10 Heavy Receiver Set is ready for sale at GrabAGun for anyone building a dependable precision .308 Win rifle from the ground up.
