ALG Defense AK-47 High Energy Main Spring

The ALG Defense AK-47 High Energy Main Spring is a performance replacement spring designed for AK-47 and AK-74 platform rifles. Built for shooters who want a simple internal upgrade, it increases mainspring torque to help reduce lock time and improve ignition consistency. That makes it a practical choice for customers looking to enhance reliability and overall trigger system performance in a hard-use AK setup.

This spring is made from chrome silicon single-wire material and is fabricated to ASTM A401 specifications. ALG states that it develops 25% more torque than a standard factory main spring, giving it a performance edge for shooters who want a stronger, more responsive replacement than a basic stock spring.

For AK owners focused on dependable function and a straightforward upgrade path, the High Energy Main Spring is a small but meaningful component change. It fits well in maintenance builds, reliability-focused upgrades, and rifles that see frequent range or field use.
