EKOL ES 66 CO2 BB Pistol Table Top Review

No Comments

Type: BB air pistol.


Model:ES 66 / ES 66 C

Materials: All metal construction.

Weight: 2.03/2.13 pounds (920/968 grams)

Barrel: Metal rifled.

Propulsion: 12 gram CO2 x 1.

Action: Semi auto, single & double action.

Ammunition Type: 4.5mm BB's.

Ammunition Capacity: 15 round magazine.

FPS: 410.

Trigger Pull: The trigger pull with both the EKOL ES 66 CO2 BB Pistols is fairly heavy in double action mode as the hammer spring is fairly firm. In single action mode the trigger pull lightened up a lot and allows for more precise shooting when required. The double action pull is fairly long and the release point is fairly far back.

Accuracy: I have not shot either of these EKOL ES 66 styled airguns but I have conducted a similar test using a similar EKOL BB  Pistol, the EKOL ES 55 which is basically the same base gun with a different slide. I would expect all of the EKOL airguns to shoot about the same. Based on my past experience the ES 66 C and ES 66 should shoot right around 420 fps or more and get 1-2 inch groupings from 30 feet out. We will find out for sure when I conduct my official Field Test Shooting Review for them.

Build Quality: The EKOL ES 55 comes from a company that primarily makes blank pistols. EKOL makes this gun directly from a similar model (The EKOL Sava) that shoots blanks so in many ways the ES 55 and ES 66 are designed more like a real gun than an airgun. The EKOL ES 66 Series is all metal with rubber grips and feels fantastic in the hand. There are really no plastic parts to speak of and I could not find any quality concerns on these airguns at all! The Chrome finish is something you don't often see in airguns but does look nice, just watch out for those finger prints ;)

Realism: The EKOL ES 66 CO2 BB Pistol is not an exact replica but does look a lot like a browning Hi-Power other than some small cosmetic differences. The basic size and shape is very close. With the shorter EKOL 66 C, this similarity is harder to see.

  • All metal construction - very heavy and solid feeling gun.

  • Double and single action trigger / hammer.
  • One of the few BB pistols with a rifled barrel.

  • Some parts don't function - slide release - slide when CO2 is in the gun.
  • No cutout ejection port.
  • Sights are none adjustable.
  • Double action is a bit heavy and trigger take-up is long.


EKOL makes several blank guns and I have reviewed many of them back when we used to be able to import more varieties of blank guns here in Canada. What makes the EKOL airgun version kind of different than most airguns out there, is that it is made very similarly to the way EKOL makes their blank guns. Many parts are interchanged so in some ways the airgun is a lot like the blank gun version which one could say is a lot like how a real gun is made. What I am getting at here is that the EKOL ES 66 and ES 55 look and feel more like real guns than an airgun. Make sure to pick one of these EKOL airguns up before we run out, our supply for them is limited and when they are gone we may not be able to get any more?
