KODIAK DEFENCE, BRASS BUSHING

This Brass Bushing replaces the Nylon Bushing in WK180Cs (WK180C-U-14.)  No need to drill into your upper receiver – simply remove the nylon bushing present in your rifle and drop this in its place.  The notched section of the rim of the bushing allows you to insert it into the upper receiver without removing the barrel nut.  (Colour in photo is not representative of product.)
