I wanted my .300 Blackout AR to be easier to shoot well for hunting season, so I dropped in a TriggerTech 3.5 lb flat trigger. The install took only a few minutes while I was reading the instructions as I went, and the range test afterward felt light, smooth, and crisp.
Why I Swapped the Trigger
This is the same .300 Blackout AR I built with youth hunters in mind. A lighter, crisper trigger helps with accurate shot placement when the pressure is on, whether I’m behind the rifle or one of the kids is. If you’re curious about why I hunt with an AR in the first place, I wrote about that in Versatility of the AR Platform.
How the Install Went
Before anything else, make sure the rifle is clear. Then open the lower, remove the existing trigger, and pull the securing screw. Keep the new TriggerTech assembly in the cocked position as you carefully lower it into the lower so you don’t trip the trigger.
- Insert the rear pin (I like right to left).
- Rotate the trigger as shown so the safety will not interfere.
- Install the safety selector halfway between safe and fire—other angles can damage the trigger.
- Insert the second pin.
- Firmly tighten the two snug-down screws evenly so the assembly is secured.
- Reassemble the grip, spring, and upper, then function check: cocked, trigger pressed with safety on (shouldn’t fire), safety off (fires).
In the video I dry-fire checked it first, then put a couple of live rounds through it on the range. Those two rounds felt really good—light, smooth, and crisp—and I planned to put another 15 or so through it to confirm accuracy.
Wrapping Up
A drop-in TriggerTech flat trigger is a quick upgrade on a hunting AR. If you’re also thinking about quieting that .300 Blackout down for youth hunters, check out Do I Need a Suppressor? And if you’re still dialing in the optic, here’s how I lap and mount a scope.
