White Molasses lol's Review of Fostech Echo AR-II Drop-In Binary AR-15 Trigger

Love this trigger. Works as advertised. You DO NOT need a specific Fostech BCG for the Echo 2. Any FULL AUTO BCG works. My only complaint is the safety selector levers are complete garbage and they are proprietary.
Pros:
  • Works great out of the box.
Cons:
  • Safety selector is bulky plastic junk
Best Used for:
  • Plinking and home defense
Would Recommend: Yes
