Echelon 4.0 C Install
Finally got mine for the Echelon, which has been my EDC for the last year. Love the craftmanship on this, and it was a painless switch, as far as swapping the COG and mag release. There will be a learning curve for the new grip angle, as far as quickly acquiring your optic sight picture. Feels great in my larger hands, and seems to help with taming the recoil. I'm guessing due to the added weight and angle? Overall very satisfied and highly recommend.
