The .22 Conversion Kit fits the 1858 Remington revolvers manufactured by Uberti & Pietta. This .22 Conversion Kit will also fit ASM with minor adjustments. All .22 Conversion Kits fire standard .22 LR ammo; including .22 Long and .22 Short.

One Konverter will allow the conversion of both .36 caliber and .44 caliber to .22 LR.  There is a .36 caliber barrel adapter and a .44 caliber adapter bushing in the kit along with adjustment washers allowing you to adjust the cylinder to barrel gap for any of the full size Remington models.  If you own multiple percussion revolvers, one Konverter can easily be moved from gun to gun.

If you choose to use the new Improved Ejector you will need to cut a small diameter port in the revolver frame. This way you can load and unload without removing the cylinder.

This Improved Ejector fits all 1858 Remington models and works to eject all size cartridge cases, from .22LR to .45 LC. The direct, straight back ejection motion and spring loaded action makes ejecting your spent cases quick and easy. The built-in cylinder pin secures the ejector to your revolver by simply removing and reinstalling the loading lever and replacing the stock cylinder pin with this assembly, then reinstall the loading lever and screw.
