Related Posts:

Type: BB air pistol.


Model:ES 55.

Materials: All metal construction.

Weight: 2.25 pounds.

Barrel: Metal rifled.

Propulsion: CO2 x 1.

Action: Semi auto, single & double action.

Ammunition Type: 4.5mm BB's.

Trigger Pull: The trigger pull on this gun is fairly heavy in double action mode as the hammer spring is firm. In Single action mode the trigger pull lightened up a lot and allows for respective target shooting.

Accuracy: I conducted my test shooting from a target 20 feet away in a free standing position. The EKOL ES 55 gave me a respective 2 inch grouping. I think with practice, I could get this easily down to a 1 to 1.5 inch group as I was not initial comfortable shooting this gun. After shooting it for a while I did become used to the characteristics of the ES 55.

Build Quality: The EKOL ES 55 comes from a company primarily making blank guns. EKOL makes this gun directly from a similar model (The EKOL Sava) that shoots blanks so in many ways the ES 55 is designed more like a real gun than an air gun. The EKOL ES 55 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 this gun at all! The gloss black painted finish is flawless on this gun!

Realism: The EKOL ES 55 is not a replica of any one gun so to speak, it looks a bit like a bunch of guns: maybe the closest one being the Glock? It does have characteristics from other guns but in terms of does this look like a real gun? Yes very much so, and when you hold it in your hand, you will find it hard to believe its an airgun.

This is my first ever air gun from EKOL, I have been very happy with their blank guns so it does not surprise me that their CO2 BB guns are just as nice. The EKOL ES 55 is a well built very solid CO2 BB shooter and has excellent velocity and respectable accuracy from its rifled barrel. I found the gloss black finish to be very good on the ES 55. That combined with the rubberized grips makes this BB pistol a very attractive air gun. The EKOL ES 55 isn't the least expensive BB pistol on the block but it won't break the bank either and at the end of the day you get really good value for a gun you will hopefully own a lifetime.
