Finicky but good - FRT Triggers FRT-15L3 AR-15 Forced Reset Trigger, 3 Position, Drop-In Compatible w/Ambidextrous Safety Selector and Anti-Walk Pins

The trigger was simple and straight forward to install I mean it's a drop in it should be. The only issue is with fully seating the upper and lower together there's a certain order of operations to it and I had to actually actively follow a video on yt from deskpop to get my upper to fully seat nothing major probably something u can figure out and get down after doing it a few times. Mine came totally gobbed with grease on the inside just a massive spoon full that I just spread around with a swab. There's also been reports of some internal screws walking ir coming loose so I recommend checking the trigger pack itself over before fully installing the trigger and loctite anything that seems loose. Would also like to point out some people recommend swapping up to an h2 buffer weight to help reliability currently only about 20 to 30 more dollars to the overall price if you don't already have one installed. Would recommend for anybody with an ar15 trigger compatible firearm.
