This Rock River Arms match AR-15 trigger kit is designed to be used with Mil-Spec lower receivers with .154” trigger and hammer pins and can also be used with anti-rotation pins for a more secure fit. However, the larger .1555″ pins will give you a more snug fit. The versatility of AR-15’s is extended even further as some parts are interchangeable with AR-308 and DPMS LR 308 style rifles and this trigger is compatible with both. Another feature is the lightened hammer which allows for a decreased lock time while still maintaining reliable primer ignition even with hard military surplus ammo. This fire control group provides a custom tuned feel at an affordable price whether you are upgrading an old trigger or building a new rifle.

This match grade trigger provides a crisp, 4 to 5 lb., 2-stage, trigger pull to improve accuracy for competition or varmint shooting. Sear engagement point is located behind the hammer to reduce pull weight. Low mass hammer speeds lock time. Includes trigger and hammer pins.
