AR-15 Magazine Catch Button

Features

1. Mil-Spec Dimensions — Built to AR-15/M16 mil-spec drawings for drop-in fit with any standard lower receiver.
2. Steel Construction — Machined from hardened steel to resist deformation under repeated thumb pressure and hard use.
3. Phosphate Finish — Black phosphate coating provides corrosion resistance and a non-reflective, matte appearance that matches mil-spec lower parts.
4. Knurled Face — Cross-hatched texturing on the button face gives a positive grip for quick, reliable magazine releases with bare or gloved hands.
5. Threaded Stem — Standard threaded post mates directly with the magazine catch shaft on either side of the receiver.
6. Lower Parts Kit Replacement — A direct replacement for lost, worn, or upgraded factory mag catch buttons during builds or repairs.
7. Broad Platform Compatibility — Fits standard AR-15, M4, and M16 pattern lower receivers chambered in 5.56 NATO, .223 Rem, and other AR-15 calibers.
8. Compact, Lightweight Profile — Adds no meaningful weight or bulk to the rifle while restoring full magazine release function.
