Most of the drop in triggers are match quality and priced the same, $150 up. They deliver a match trigger, 2.5 to 4 pounds, usually no creep or grittiness, and the best "break like glass."
On a tactical AR you drag down the driveway, it's a waste of money. As described, the stock issue LPK can be cleaned up. It's a 6-8 pound pull because in hard use bumping against vehicles, doorways, drop and roll, combatives, etc, light triggers are a liability. Other team members are in close proximity, no matter how hard you train everyone gets muzzle swept by a buddy with a live round in the chamber, safety off, finger on a trigger.
At that point you remember your buddy dropped in the light hair trigger that morning . . .
As long as everyone remembers that race gun parts only work well on the confines of the range, nobody has problems. It's when these things start being misapplied where the disconnects occur. Dry street tires on 20" dub rims slapped on a SUV don't offroad well.
The pistol shooters have demonstrated this a long time ago, you can win matches with a 10 pound NY trigger on a Glock. It's the shooter, not the equipment.
