Why This 20-Pack Belongs on Your Bench

Mil-spec pattern fit: Designed for AR-15 lower receivers that use the standard magazine catch and button assembly.
Bulk value: 20 pieces to support multiple builds, classes, or department maintenance cycles.

What’s in the Pack
Installation Notes (General)
Unload and clear the firearm; separate upper and lower.
Insert magazine catch from the left side of the lower; align the catch shaft on the right.
Slide the magazine catch spring over the shaft, then thread on the mag release button.
Depress the button and rotate the catch until threads are flush and function is correct.
Function check: insert an empty magazine, verify positive lock, and confirm clean release.
Armorer’s Tip: If you experience weak magazine retention, check for burrs, out-of-spec buttons, or worn catches in addition to replacing the spring.
Care & Maintenance
Keep parts clean and lightly oiled to resist corrosion.
Inspect springs during routine lower receiver maintenance; replace if kinked, shortened, or fatigued.
Avoid over-compression during installation to preserve service life.
