Geissele SSMC Super Stainless Mag Catch 05-1088

Geissele SSMC Super Stainless Mag Catch 05-1088 is a stronger replacement for the mil-spec mag catch, made from stainless steel for longevity and anti-rusting properties that standard mil-spec catches don't offer.

This Mag catch assembly installs exactly like a mil-spec component, so there's no special fitting required to swap it in. It ships as a complete assembly rather than just the catch button alone — the package includes both the magazine catch and the magazine release spring, so nothing extra needs to be sourced separately. This same part is also included standard in Geissele's Ultra Duty Lower Parts Kits, sold here on its own for builders who just want to upgrade this one component.

At 0.3 oz, this Geissele Super Stainless Mag Catch adds negligible weight while delivering real corrosion resistance over a standard steel catch, particularly valuable in humid or coastal environments where mil-spec parts tend to show rust first.

Key Features:

• Stainless steel construction for corrosion resistance
• Direct mil-spec component replacement
• Includes magazine catch and release spring
• Weight: 0.3 oz
• Also included in Geissele Ultra Duty Lower Parts Kits
• Fits standard mil-spec AR-15/M4 lower receivers
• No special fitting required
• Made in the USA

This Geissele magazine release upgrade is a small, inexpensive detail that solves a real long-term durability weak point in a standard build.
