Bolt Metal M4 AEG Trigger Pins – Upgrade Your Airsoft Experience

Military-Grade Durability
Precision-crafted from reinforced steel, these replacement pins outperform standard polymer components in high-stress scenarios. Tested under 500+ rounds of continuous fire, they maintain structural integrity where cheaper alternatives fail—ideal for tournament play or intense CQB sessions.

Seamless Compatibility
Engineered to fit 95% of M4-series airsoft rifles (including Tokyo Marui, Classic Army, and G&G models), these universal pins eliminate guesswork during upgrades. The patented trapezoidal threading system ensures secure installation without specialized tools—perfect for both beginners and seasoned gunsmiths seeking hassle-free maintenance.

3 Critical Advantages Over Competitors
✅ Impact Resistance: Withstands 2x greater force than standard aluminum pins (ASTM B221 certification)
✅ Zero Clearance Fit: Precision-machined to .003″ tolerance for consistent trigger response
✅ Corrosion Shield: Black oxide coating prevents rust formation in humid environments

Why Mechanics Recommend Bolt Pins
Unlike generic plastic pins that warp after 1k rounds (common in Chinese OEM brands), our hardened steel design:
– Reduces trigger creep by 40% according to ASGI performance tests
– Eliminates rattling noises during full-auto operation
– Survives accidental drops from 3′ heights without deformation

Quick Installation Guide
1) Remove stock pin using included extraction tool (no hammer required)
2) Align grooves with receiver slots using our laser-etched orientation marks
3) Secure in place with 5Nm torque (included torque wrench ensures factory-spec tightness)
