Closed-Bolt Full-Auto Capable Operating Group

  • 1,500.00


This is the long anticipated new full-auto capable operating group that works with Registered Sears and things like the Franklin Armory Binary Trigger.

This is a NON-NFA item that allows those with legal sears and Binary triggers to operate their guns in full auto or near full auto speeds and avoid bolt bounce and provides other improvements for full auto use.

This operating group upgrade is complete and should work in ALL previous models of our semi-auto M249s, MK46s, and MK48s.
