Style
With a new rugged front cap design, signature Donny FL body grooves and bolt endcap, the KOI is a great addition to any shrouded or un-shrouded air rifle. This model has the smallest outer diameter compared to the other Donny FL models but don’t let the size fool you. With the added vent holes around the front, it is as impressive as the others.
