THIS KIT COMES WITH EVERYTHING YOU NEED TO GET YOUR RIFLE UP AND RUNNING.


This assembly kit will fit on all Mil-Spec AR 15 lower receivers. It is also compatible with most AR 308/AR 10 rifles but requires a modified buffer and spring for proper operation.

For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working.
