Detailed Features: 

 
The convertible cylinder swaps between .22 LR and .22 WMR without tools, so you can run whatever rimfire you have on hand. Adjustable rear sights paired with a ramp front sight let you dial in the point of impact at different distances. An integrated transfer bar safety blocks the firing pin unless the trigger is fully pressed. The stainless finish handles weather well without much maintenance. 
 

Usage 

 
The .22 LR cylinder makes it inexpensive to shoot at the range, and the 6.5-inch barrel gives enough sight radius for accurate small-game work on rabbits and squirrels. The single-action trigger requires deliberate cocking before each shot, which some shooters find helps with accuracy practice. At 39 oz it's a full-size revolver, comfortable to shoot but not a pocket gun.

The Ruger Single-Six Convertible is well-regarded for the two-cylinder setup. Owners appreciate having both .22 LR and .22 WMR available in one gun, and most find the cylinder swap straightforward. The single-action trigger gets consistent praise for a clean, predictable break that rewards accuracy, though shooters coming from double-action revolvers sometimes need a session or two to adjust to the manual cocking requirement.

Accuracy and reliability are rarely questioned. The satin stainless finish and engraved grips are generally liked for their traditional aesthetics. Weight is occasionally mentioned as a downside for extended carry, and some buyers have noted minor fit-and-finish variation between individual units, though this hasn't been a widespread pattern. Overall it's considered a solid, long-term rimfire revolver.
