The Mossberg JM Pro Adjustable Match AR Trigger is a drop-in aftermarket trigger designed for competitive shooters and serious AR-15/AR-10 builders who demand a cleaner break and better control. Engineered by champion shooter Jerry Miculek, this mil-spec trigger upgrade installs directly into your AR lower receiver without gunsmithing—if your receiver has standard .154-inch pin holes, you're ready to go. The factory-set 4-pound pull weight delivers a crisp, predictable break with zero creep, giving you the repeatability you need whether you're running matches, precision drills, or high-volume range days.
What sets the JM Pro apart from the factory trigger is its adjustable overtravel. Once the hammer breaks, you control how far the trigger finger travels forward, letting you dial in the exact feel you prefer. That fine-tuning matters when you're chasing tight groups or shaving milliseconds off splits. The all-in-one design means no additional parts to source or install—just drop it in and start shooting.
Important note: Drop-in triggers are designed for mil-spec lowers with .154-inch pin holes. Some proprietary or specialty lower receivers may not be compatible, so verify your receiver specs before ordering. Once installed, take the time to check function and reliability before moving to live fire.
