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

For best performance DonnyFL recommend ordering the calibre up from your guns actual calibre; so for .177 calibre order a .22 silencer, for a .22 order a .25 silencer etc. This reduces the risks of pellet clipping and allows for minor alignment issues. Applies to all silencers.
