AR-10 Bolt Catches

AR-10 Bolt Catches

Your AR-10 bolt catch controls one of the most important functions on a .308 platform: reliable bolt lock-back and confident bolt release. Whether you’re building a new lower or fixing a rifle that won’t lock back consistently, the right bolt catch makes a noticeable difference in function and feel.

What an AR-10 Bolt Catch Does

The bolt catch engages the bolt carrier group after the last round (with a proper magazine + gas system) and allows you to manually lock the bolt to the rear or release it. If your rifle struggles to lock back, the issue could be the bolt catch, spring/plunger hardware, magazine compatibility, gas tuning, or buffer setup.

Mil-Spec Fitment Matters on .308 Platforms

AR-10 / .308 builds can vary by pattern, so always confirm platform compatibility before ordering. These parts are designed for AR-10 receivers and will not fit AR-15 lowers. If you're still gathering parts for your .308 build, start with the full AR-10 parts hub and work outward from there.
