Is this compatible with an Aero Precision EPC? — 2 Answers

Yes, this Wilson Combat Tactical Triger will fit the Aero EPC-9 lower receiver with no modification to the trigger or the lower in any manner - it's a good fit. It's a great unit - excellent two-stage with crisp break. Also, like the fact that the trigger and hammer pins are captured by springs in the cassette thus permitting pin removal in the same fashion as any mil-spec AR trigger group generally speaking. Thus, there is no need for anti-rotation pins etc. that rely on small screws or clips / etc. to secure the pins in place as would be needed for most cartridge / drop-in style trigger assemblies. Additionally, this TR-TTU-9MM trigger is built specifically for the 9mm blowback system so it is built to take the harsh punishment of that operating system resetting the hammer / trigger.
