Radian Weapons R0323 Extended Bolt Catch AR-15/M16 Black

The Radian Weapons R0323 Extended Bolt Catch is a precision drop-in upgrade for any standard AR-15 or M16 pattern lower receiver. The oversized, extended paddle provides a longer, easier-to-find contact surface, delivering the enhanced functionality Radian built the part to provide without any permanent modification to the lower itself.

Radian Weapons CNC machines the R0323 from 7075-T6 billet aluminum and finishes it in a corrosion-resistant Type III hardcoat anodized black coating for long-term durability under hard use. The extended profile keeps the standard bolt-catch geometry, so it installs as a drop-in replacement on any AR-platform lower. The included spiral roll pin lets you mount it right out of the package, and at just 0.49 oz, the R0323 adds meaningful utility without adding measurable weight to the rifle.

Whether you are finishing out a custom build or refreshing an existing carbine, the Radian R0323 Extended Bolt Catch delivers the brand's hallmark fit, finish, and function in a single, easily installed part.
