Ammunition Type: 4.5mm BB's. Ammunition Capacity: 15+1 round magazine. FPS: 396. 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.
