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

This is a must have for any AR build. This drop-in was easy to install. Selector switch is crisp with no movement. This cycles flawlessly. I am not usually impressed, well never. This is an impressive addition to my AR in .556. The only real down side is... my cost to shoot now is through the roof. Because once you start shooting. You just don't want to stop. I have had no issues with this build. I would recommend this trigger to anyone who wants to diversify their shooting experience. I would recomend installing a full-auto BCG first. Just thought I would throw this review out there if someone was on the fence on buying one. Hope this helps.
