The Henry Lever Action in .17 HMR has a 20" octagonal barrel, blued steel, and an American walnut stock. The octagonal barrel is traditional Henry styling. The flat sides are heavier than a round barrel of the same steel, which adds some muzzle weight and can help dampen vibration, though the practical accuracy difference between octagonal and round is minor. What matters more is the .17 HMR cartridge itself: a fast, flat-shooting rimfire round that works well on squirrels, rabbits, and similar-size targets out past 100 yards.

Detailed Features: 

 
The front sight is a brass bead; the rear sight is an adjustable semi-buckhorn with a white diamond insert, giving you a well-defined sight picture. The manual safety operates via a quarter-cock position on the hammer. The American walnut stock has a satin finish and a standard grip profile. Henry's lever actions are known for smooth factory cycling without needing a break-in period.

Owners of the Henry .17 HMR lever action tend to come from two groups: small game hunters who want a fast-shooting accurate rimfire, and collectors who appreciate Henry's traditional styling.

Craftsmanship is the most common praise. The blued finish and walnut stock look sharp, and the fit-and-finish quality is consistently described as above average for the price segment.

Accuracy in .17 HMR is generally well-regarded. Owners report flat shooting and good groups at hunting distances. The cartridge's performance matches what the rifle promises.

The lever action itself is smooth and gets regular positive mentions. It cycles cleanly and the feel of working the lever on a Henry is a point of satisfaction for many owners.

Price is a discussion point. Some feel it is higher than comparable lever rimfires. Those who have held and shot the rifle tend to feel the price is justified by the quality; those comparing on paper alone sometimes question it.

A few users mention interest in adjustable sights or scope mounting options for longer-range varmint use, since the .17 HMR is capable of stretching beyond what open sights comfortably handle.
