FPS FPS Version 2 Ergal Ball Bearing Spring Guide for KING ARMS-SPECNA-MACO-MAW-DBOYS QD gearbox version

The FPS GMAW Spring Guide is a high‑quality ERGAL (7075 aluminium) ball‑bearing spring guide designed specifically for Version 2 quick‑change gearboxes used by KING ARMS, SPECNA, MACO, MAW and DBOYS. Engineered for strength, smooth operation and long‑term reliability, it’s an essential upgrade for any QD‑equipped M4/M16 platform.

The CNC‑machined ERGAL body provides exceptional durability while keeping weight low, and the integrated ball‑bearing system ensures smooth spring rotation during compression and release. This reduces stress on the spring, improves consistency and helps maintain stable FPS over time — especially in upgraded builds.

As with all FPS components, the GMAW spring guide is 100% Made in Italy, offering premium craftsmanship and precise tolerances for a perfect drop‑in fit.
