The F.A.B. Defense Fab Defense UAS Precision Stock PRO Conversion Kit for Ruger 10/22 delivers a high quality upgrade that blends a classic bench-rest silhouette with modern tactical versatility, enhancing stability, control, and speed for precision shooting and rapid field use. This stock features a ventilated 6061 T6 billet aluminum handguard and upper rails that support secure mounting of any 1913 MIL-STD Picatinny optics and accessories, while its quick-drop-in installation makes upgrading smooth and straightforward. An integrated adjustable cheek-rest offers five height options to tailor eye alignment and comfort, and a side folding buttstock (left folding by default) provides compact carry without sacrificing swing and cheek weld integrity. Quick-Detach sling swivel sockets on both sides, along with an ergonomic design, reduce fatigue and improve grip, while thoughtfully placed finger grooves and a contoured backstrap enhance trigger operation under dynamic conditions. Built from durable fiberglass reinforced polymer, the UAS Precision Stock PRO combines rugged reliability with a lightweight profile, and its compatibility extends to standard Ruger 10/22 rifles and all 1913 picatinny-based optics, making it an excellent upgrade for shooters seeking precision, versatility, and a refined handling experience.
