Angel Custom CNC Steel Ball Bearing Spring Guide with 130% and M120 Springs

For Spring-Powered Tri-Shot Airsoft Shotguns

Upgrade your spring-powered tri-shot shotgun with the Angel Custom CNC Steel Ball Bearing Spring Guide, designed for serious players who demand performance, reliability, and durability. Engineered specifically to handle higher power setups, this reinforced spring guide kit is compatible with most M870-styled tri-shot shotguns, including popular platforms like Marui M3, Super90, CYMA M870, and BO Manufacture FABARM STF12. Whether you’re hitting CQB fields or outdoor skirmishes, this spring guide kit ensures smoother performance, higher FPS, and consistent shot-to-shot reliability.

Premium CNC Steel Construction

The Angel Custom spring guide is CNC-machined from high-quality stainless steel, ensuring precise dimensions, exceptional durability, and long-lasting performance under heavy use. Unlike stock polymer or low-grade metal spring guides, the CNC steel construction resists bending, deformation, and wear—even with reinforced, high-tension springs. Its reinforced design is specifically engineered to accommodate higher-power springs without compromising your shotgun’s longevity or reliability.

Ball Bearing Design for Optimized Performance

One of the standout features of this spring guide is the ball bearing mechanism. Unlike traditional spring guides, the ball bearing system reduces friction during spring compression and decompression. The result is smoother, more consistent performance, faster reset times, and less stress on your gearbox and internal components. Players who upgrade their shotguns with reinforced springs will immediately notice the improved trigger response and more reliable cycling.

Increased Power with 130% and M120 Springs

This kit includes 130% and M120 springs, providing a significant power boost for spring-powered tri-shot shotguns. These springs are designed to increase FPS while maintaining safe, reliable operation with tri-shot platforms. Paired with the ball bearing spring guide, these upgraded springs allow for:

• Higher projectile velocity and extended range

• Consistent shot-to-shot performance

• Improved trigger reset and smoother pump action

Whether you’re competing in competitive airsoft or playing weekend skirmishes, this kit gives your shotgun a performance edge over standard setups.

The Angel Custom CNC Steel Ball Bearing Spring Guide Kit is engineered for broad compatibility.
