AR-15/M4/M16 3 Round Burst Kit


3 Round Burst trigger components for your M4/M16 NFA builds.


This M16A2 3-Round Burst Kit is made to the highest standards and workmanship.  Installation of this set in your post 86 lower receiver machine gun will give you a ‘three-round burst’ capability as in the M16A2. Not legal for installation in anything but a licensed machine gun. Originally, these were manufactured for U.S. government contracts back in 2002. Now, there are only 3 sources for these hard to find 3-round burst kits available in the USA. All you need is this and an M-16 lower parts kit and you have a 3 round burst complete kit. We also sell M16 lower parts kits. The only difference between our A2 kit & the M4 burst kits is that the A2 Kit has longer dwell times and the M4 burst kit handles a faster cyclic rate.
