LaRue Tactical is now selling a kit to convert a Ruger 10/22 into an arrow firing rifle. It replaces the barrel with a heavy profile barrel that can only chamber .22 blanks. An arrow is inserted into the barrel and a .22 Blank will propel it at 435 ft/sec.
The basic kit (barrel + arrows) costs $442. The Deluxe kit which includes many accessories costs $599.
I could really use one of these kits to sort out a pest problem I have, but for that price I would rather buy a high-end .22 air gun and fit it with one of my .22 rimfire suppressors.
