Rachis™ [rey-kis] Recoil System for Full and Compact frame GLOCK™ GEN 4 pistols


Designed for reliable performance, our CARRY Model features a hollow, lightweight Nitro-Wear® heat treated ETD 150® alloy steel guide rod. The COMPETITION Model, utilizing the same hollow guide rod casing, is permanently bonded with a Tungsten Carbide Core creating our heavyweight version. Both are used in conjunction with a conventional ISMI™ non-captive single stage round wire recoil spring and a 12L14 alloy steel guide rod bushing.


These precision CNC machined high strength guide rods are hardened to resist spring wear and corrosion using a patented proprietary heat treatment process. The strong, thin wall tubular design of our CARRY Models weigh the same as factory recoil assemblies. COMPETITION Models have an inner core of Ultra Micrograin WC (Tungsten Carbide) with 10% Co (Cobalt). With an approximate 400% increase over the weight of the factory recoil assembly, these high density guide rods provide additional non-reciprocating mass improving recovery times and yielding faster target acquisition of follow up shots. All guide rod ends are crowned to provide a sleek yet distinctive look. Both models are available in either Black Oxide or polished finish. These reliable, high quality firearm components have a 100% Lifetime Warranty. Recoil springs are manufactured from premium Chrome Silicon alloy which is heat treated, shot peened and stress relieved after winding. They carry a 12 month replacement warranty. The Black Oxide finished bushing serves to keep both guide rod and recoil spring centered in the pistol slide. All components are Made in America.


Includes Guide Rod (Carry or Competition), Recoil Spring and Guide Rod bushing.
