CMMG Zeroed Extended Bolt Catch Features The CMMG Zeroed Extended Bolt Catch is machined from steel and finished for durability giving the AR-15 platform a stronger longer-lasting bolt catch than the thin factory stamping. The extended dual paddle design gives the shooter a much larger target to strike during reloads and malfunction clearances cutting down on fumbled bolt drops. A tactile machined surface on the paddle helps the thumb or support hand find and engage the catch by feel alone which matters most when the shooter s eyes stay on the threat or the target. This combination of size and texture is what separates a combat-ready control from a stock part. Installation follows the same procedure as the factory bolt catch so the upgrade drops into any standard AR-15 lower without special tools or gunsmithing. CMMG designed the extended paddle to maintain reliable spring tension and catch engagement so function is never traded away for ergonomics. Builders upgrading a duty competition or home defense rifle gain a more confident repeatable bolt catch operation every time the gun runs dry. This is a straightforward affordable upgrade for anyone who wants their AR-15 to run as well as it looks.
