This Howell Arms conversion cylinder converts your Uberti 1858 Remington Navy revolver in 36 caliber percussion to fire the .38 Special cartridge using hollow base or heeled type bullets. You can also use 38 Special Hollow Based Wadcutter ammunition. To overcome the larger bore of the original barrel, it is recommended that you use hollow based or heeled type bullets.

Please see our selection of cowboy ammunition.

(If, after installation, you are unsure of the fit, please take you revolver to a competent gunsmith to make sure you have cylinder installed correctly.)
