LBE Unlimited AR-15 Mil-Spec Magazine Catch Assembly Black Steel

The LBE Unlimited ARMCASY AR Parts Mil-Spec Magazine Catch Assembly delivers reliable magazine retention and release for AR-15 platform rifles. This precision-machined component ensures consistent magazine changes under stress while maintaining proper lockup during rapid fire sequences.

What Makes This Different

Unlike standard polymer alternatives, this steel construction magazine catch assembly provides superior durability under high round counts and temperature extremes. The mil-spec dimensions guarantee proper fit with all standard AR-15 lower receivers and magazines. Heat-treated steel construction resists wear from repeated magazine insertions and releases that can degrade softer materials over thousands of cycles.

Key Features

• Precision-machined from heat-treated steel for maximum durability
• Mil-spec dimensions ensure compatibility with all standard AR-15 lower receivers
• Black oxide finish provides corrosion resistance and reduces glare
• Spring-loaded mechanism maintains consistent tension throughout service life
• Beveled edges facilitate smooth magazine insertion and release
• Drop-in replacement requires no gunsmithing or modifications
• Compatible with both aluminum and polymer magazines

Field testing demonstrates reliable function through temperature ranges from -20°F to 140°F without binding or failure to release. The hardened steel surface maintains its shape under the repetitive stress of competitive shooting where magazine changes exceed 100 per session. Law enforcement and military users report consistent performance in sandy, muddy, and wet conditions where magazine retention becomes critical for operational success.
