The ULTIMATE spring guide is built to deliver maximum durability and efficient force transfer even under high spring tension. Its steel construction and integrated bearing reduce friction during spring compression, ensuring a smoother and faster firing cycle. The rotating base allows the spring to twist freely, reducing wear and helping to increase rate of fire.
For best performance, use it in combination with a bearing piston head to optimize alignment and spring rotation during compression. Thanks to its high-quality build, this guide is ideal for high-end upgrades and reliable in standard AEG setups as well.
