The Liberty Fighting trigger averages at approximately 6 pounds and features a Nickel PTFE coating to reduce friction and maintain lubricity. With the included slave pin, this two-piece trigger is easy to install in your lower receiver. The trigger and hammer pin diameters are Mil-Spec .154” for maximum compatibility with most AR-15 rifles.

The revolutionary, patent-pending Drivelock design, uses three independent wedges that interface with the angular grooves in our proprietary barrel nut. This system clamps the rail onto the steel barrel nut with extreme force and precision, while also driving the handguard rearward towards the upper receiver. The slightly larger ID of that extrusion gives us more real estate around the gas block, even more rigidity than the M76, and takes longer to heat. We are not discontinuing the M76. That will remain in full production. We are just adding the M89 to the lineup. FEATURES:
