Here is my official Field Test Shooting review for both the EKOL ES 66 and ES 66C CO2 4.5mm BB Pistols. Make sure to watch my Table Top Review for more information on the Features and Specifications for both of these all metal Turkish made air pistols.
As with my standard Field Test Shooting Reviews, I shoot 5 rounds through my Chronograph to get a real world Velocity reading in feet per second. I also shoot 10 rounds into a paper target using a semi-rested position from 30 feet away. Since I had two versions of the EKOL ES 66, the long and short barreled versions I decided I would test pistols both on the Chrony and just the long barrel version for the accuracy testing.
