The Henry Pump Action Octagon (Henry part no. H003TM) is a slide-action rimfire rifle chambered in .22 WMR, built around a blued octagonal barrel that revives the look of the classic shooting-gallery guns of an earlier era. Henry Repeating Arms gives shooters more reach and energy than a standard .22 LR pump gun while keeping the same traditional slide-action cycling and adjustable iron sights. The 20.5-inch barrel and hammer-style safety round out a rifle built for plinking, small game, and pest control.
