In least to best order:

Stock trigger: Not too bad, but not too great either, much more heavy than my ATS's or Cocker

R/T: Wonderful when properly tuned, I just never play with it to take the time to do so

WAS Board: Its electronic, so that counts for something right?

Origional E-Grip: Even with a single trigger and spring changes it provides a nice feel, could use a better trigger to complement the electronics.

E-Bolt: This is the way the A-5 should have been. Morlock board, Humphrey noid, two rams off the same noid, so simple yet so elegant. Battery issues are a thing of the past, used for 2 years and I could go another year or so with out changing the battery. The only non e-bolted A-5s I'll build from here on would be pistols and loners, once you take that step, you can't go back. I'm just glad to have picked up a well build project to learn off of.
