A lot of good triggers mentioned so far, but not much about use.
We have our range toys, hunting, target and Home Defense guns. And then there are some with Duty guns.
So the best trigger for one will not always be the best for the other.
I have several triggers in my AR’s from stock mil-spec to drop in one piece.
Here’s what I like.
The PSA enhanced trigger is ok if you’re on a tight budget. But you would be much happier spending just a little more.
For the best trigger for your money would be the AGL ACT (Advance Combat Trigger) I really like this trigger. What puts it above the others in its class is the trigger is nickel boron like the others, but the hammer and pins are nickel Teflon.
It make a good all around trigger, and great for home defense and duty use.
Then there are the Hiperfire triggers. These have some of the hardest hitting hammers that will be sure to set off the hardest of primers.
I like their Heavy Gunner trigger. I put in the same use as the ACT.

For hunting, I like the LaRue MBT. I find it a little to light for duty and home defense.
For target and hunting a one piece drop in like the Risen 140 is great when you want that very light trigger but don’t want to spend a lot of money.
Now there are others but the price goes up and I don’t think you were looking to spend more then $129.
