Didn't work for me - The Triggered Company The Disruptor AR-15 FRT 3 Position Drop In Forced Reset Rifle Trigger w/ Ambidextrous Safety Selector

I tried a full series of buffers and springs, even an adjustable gas system. I could not get this trigger to reliably reset in FRT fire. The rifle is a Daniel Defense M4A1, I swapped the lower off a V7 with a rare breed in it and it ran flawlessly. It wasn't a component or tuning issue. The trigger just would not run. It may run in a different rifle. But if you are running a Daniel Defense definitely dont get this trigger. However the DDM4A1 is a pretty good M4 clone. So, I would probably just pick a different one regardless of what you are running. ... One more thing, the trigger is super squishy and gritty in both semi and frt. This was just an all around bad trigger for me in every way.
