The triggered company partisan disruptor ar-15 frt 3 position drop in forced reset rifle trigger w/ - The Triggered Company Partisan Disruptor AR-15 FRT 3 Position Drop In Forced Reset Rifle Trigger w/ Single Side Safety Selector

Installation went well. Detailed instruction is non-existent in the package. The Triggered Company ignorantly expect the installer to have access to their "on-line" instructions while working in your shop. Closing the upper and lower housings is where the problem arises. One must pull the bolt charging handle rearward about .100 thousandths of an inch so the trigger actuator doesn't interfere with bolt carrier. This piece of information is buried way down in the "on-line" instructions and is not intuitive because the bolt carrier will interfere with the lower housing if retracted too far.
