Geissele Super Stainless Mag Catch

The Geissele Super Stainless Mag Catch replaces the AR-15's cast magazine catch with one machined from solid stainless steel and finished for corrosion resistance. It is not a bigger button or an ambi conversion; it is a quiet durability upgrade to the part that actually holds the magazine in the rifle, and it ships with a fresh release spring so the whole engagement surface is renewed.

On a hard-use or wet-environment rifle the factory cast catch is a wear item that can round off or corrode over thousands of reloads. The stainless Geissele part keeps engagement crisp and resists the rust and galling that affect a plain steel catch, while staying in the standard left-side location with the standard manual of arms.

Pair it with an extended button like the Magpul Enhanced or ODIN XMR Gen II if a larger target is also wanted; the Super Stainless catch keeps the factory threading, so it accepts standard and most aftermarket release buttons. This is the pick for a builder who cares about the catch itself lasting, not about adding ambidextrous or oversized controls.
