Execellent frt - The Triggered Company Partisan Disruptor AR-15 FRT 3 Position Drop In Forced Reset Rifle Trigger w/ Single Side Safety Selector

Runs great with real H3 dead blow buffer and standard carbine spring in 10.5"-16" 5.56 bbls. Easy to install, fun to use, great product. Once installed, and when you add your upper, put rear lug in first, pull the charging handle a little bit, drops in, push your pins in. A little different than what yer use to, but nothing you can't handle.
