Brass Stacker G4G1918HB Rachis Recoil System for Glock Generation 4 Compact Frame Pistols, Black
The Rachis [rey-kis] Recoil System "Competition" Model for Glock Generation 4 G19, G23, G32 etc. compact frame pistols is designed for reliable performance. It utilizes the same hollow guide rod casing of our "Carry" model which is permanently bonded with a (WC) Tungsten Carbide Core creating our heavyweight version. With an approximate 400% increase over the weight of the factory RSA (recoil spring assembly), these high density guide rods provide additional non-reciprocating mass improving recovery times and yielding faster target acquisition of follow up shots. The precision CNC machined high strength guide rod is hardened to resist spring wear and corrosion using a patented proprietary heat treatment process. Recoil springs are produced exclusively for this system by ISMI and are heat treated, shot peened and stress relieved after winding. The alloy steel, black oxide finished bushing serves to keep both guide rod and recoil spring centered in the pistol slide. Unit includes guide rod, 18lb factory weight recoil spring and guide rod bushing. All components are Made in America. Guide rod and bushing have a 100% Lifetime Warranty. Recoil spring has a 12 month replacement warranty. Will NOT work with Glock Generation 1, 2 or 3 pistols. Will NOT work with any Glock Gen 4 Sub Compact pistols. Will NOT work with Glock Gen 4 models 34 or 35.
