Mossberg 96010 JM Pro Adjustable Match AR Drop-In Trigger 4 lb - Fits AR-15/AR-10 (.154\" Pins)

The Mossberg 96010 JM Pro Adjustable Match AR Drop-In Trigger is a purpose-built fire-control upgrade for AR-pattern rifles, centered on a crisp, creep-free break and a factory-set 4 lb pull weight. It is engineered to fit both AR-15s and AR-10s that use the standard .154\" trigger and hammer pin holes, allowing it to drop directly into a mil-spec lower without permanent modification.

Constructed from steel with a tough black finish, the JM Pro delivers the refined break that competitive shooters and precision rifle builders look for. The trigger ships factory-set at 4 pounds of pull, and a secondary screw provides user-adjustable overtravel so the shoe-to-sear geometry can be tuned to individual preference without changing the pull weight.

Whether you are tightening up a match AR-15, dialing in a long-range AR-10, or simply replacing a worn factory trigger, the Mossberg JM Pro brings match-grade performance to the AR platform in a true drop-in package.
