Great for its purpose - Fostech Echo AR-II Drop-In Binary AR-15 Trigger

This trigger is a little difficult to install, but once it’s in it runs like a dream. The selector switch is crisp and a little tougher to toggle than on a typical AR trigger group’s, but I like it.

It’s definitely a mushy trigger, though. There isn’t really a “wall” to break when pulling it. It’s got a lot of travel, too, so use it on a gun where you want volume of fire over accuracy. All of that owes to how it operates, though. It’s hard to imagine a binary trigger being as crisp as, say, a Trigger Tech adjustable trigger. Just different design requirements.
