I've recently bought a PSA EPT trigger and also a BCM PNT enhanced trigger. I've yet to fire either, so I can comment only on the trigger pull. I'm comparing these to the mil-spec trigger in my DPMS.
The PSA that I have is a little smoother than the BCM that I have. I'm sure that will vary slightly with each trigger group shipped based on how much coffee the polishing expert had that morning. But both are a MAJOR improvement over the standard mil-spec trigger. It's the difference between a rough-azz chirt road and a nice, freshly paved road. The creep is so smooth on the PSA that it's hardly noticable, and the brake on both are nice and crisp.
PSA can be had for $30, BCM for $60. I'm ordering another PSA for my DPMS.
