Overview
The Cmmg Zeroed AR-15 Bolt Catch is a standard type bolt catch designed to securely hold the bolt in the rearward position after the last round is fired, allowing for easier magazine changes. This component is crucial for ensuring reliable operation during shooting, as it allows the shooter to quickly recognize when the magazine is empty. You'll typically find this bolt catch in builds that utilize a carbine gas system and are chambered in 5.56 NATO, making it a common choice for a variety of tactical and sport shooting applications.
