The Henry Repeating Arms Octagon Large Loop Rifle is a lever-action rimfire chambered in .22 Magnum (.22 WMR). The 20.5-inch octagonal barrel gives it a classic profile, and the American Walnut stock with blued metal finish carries that look through consistently. At 6.25 lbs and 38.5 inches overall, it handles well on the range or in the field.

Detailed Features 

 
The octagonal barrel is more than an aesthetic choice. The profile adds rigidity compared to a round barrel of similar weight. The 12+1 capacity is good for a tube-fed .22 WMR lever action. The large loop lever makes cycling smooth and gives gloved hands more room to work. 
 
The Marbles sights are among the better factory iron sights available on a production rifle. The semi-buckhorn rear is fully adjustable for windage and elevation; the reversible white diamond insert gives you a light-on-dark aiming reference. Henry's lever actions are known for smooth cycling, and this one is no different. 
 

Usage 

The .22 WMR hits harder than .22 LR at distance, which makes it a better choice for small game or pest control out to 100 yards or so. For range shooting the cartridge is more expensive per round than .22 LR, but it delivers more consistent performance at longer distances. The large loop and smooth action make it a rifle that's genuinely enjoyable to run, not just accurate.

The Henry Octagon .22 WMR Large Loop lever rifle draws consistent positive feedback. The most common themes are build quality, fit and finish, and how smoothly the action cycles.

Owners describe the Henry as one of the better-built .22 WMR lever guns available. The octagonal barrel and walnut stock hold up well and look good doing it. The Marbles sights are well-regarded for a factory iron sight setup. The lever action is smooth out of the box, which makes shooting it a lot more pleasant than some competing brands.

For small game and varmints, owners report the .22 WMR performs reliably at reasonable hunting distances. At the range it's a fun, low-recoil gun that doesn't get old to shoot.

Critiques are minor. Some smaller-framed shooters note the overall length and weight are on the larger end for a .22. Ammunition cost for .22 WMR versus .22 LR comes up occasionally. It's worth noting if you plan to shoot high volumes. Availability varies regionally, and a few buyers found pricing higher than they expected for a rimfire, though most agree the quality justifies it.
