The ALG Defense AK Recoil Spring (brand part no. 04-231-F) is a one-of-a-kind design manufactured from chrome silicon steel to resist both impact shock and spring relaxation over time. Two to three dead coils built into the center of the spring change its natural frequency, which prevents damaging harmonics from building up during repeated cycling. That same design also helps the spring hold its free length better than a standard recoil spring, so it keeps consistent tension over a longer service life. For an AK owner replacing a tired factory recoil spring, this is a direct, drop-in upgrade built to outlast the part it replaces.
