CTM - Recoil / Hammer Spring Set For Hi-Capa

CTM Tac Replacement Recoil & Hammer Spring Set for Hi-Capa 4.3 / 5.1

Restore your sidearm to peak factory performance with the CTM Tac Replacement Recoil and Hammer Spring Set. Precision-engineered for the Tokyo Marui Hi-Capa platform, this drop-in refresh kit is designed to return your pistol to its original mechanical timing and cyclic feel.

Over thousands of cycles, factory springs naturally lose their tension, leading to sluggish slide travel, inconsistent gas efficiency, or light primer strikes. Built strictly to Tokyo Marui OEM specifications, these high-quality replacement springs mimic the exact compression ratings and spring weights of the original components. This makes the kit an essential addition to any tech bench for routine maintenance, reliable repairs, or as a critical backup in your field kit.

Key Features

• OEM-Spec Performance: Carefully wound to mirror original Tokyo Marui spring tension profiles, ensuring flawless cycling and reliable hammer drop without changing your gas consumption.
• Complete Cycling Refresh: Includes both the primary recoil spring and the internal hammer spring to completely overhaul the cycle and ignition timing of your pistol.
• Premium Spring Steel Construction: Engineered for long-term fatigue resistance, retaining structural memory and elasticity over extended use.
• Drop-In Fitment: No modifications or shims required; simply swap out your worn components during routine maintenance.
