The RD1851U was designed for the Uberti 1851 or 1861 Navy percussion revolver with .375" grooves and converts it to fire the .38 Long Colt cartridge using hollow base or heeled type bullets. You can also use 38 Special Hollow Based Wadcutter ammunition. This model gives you the superior handling characteristics and outward appearance of the honored Navy, with the convenience of cartridges! Once the loaded cylinder is in place, it is extremely hard to tell it is a cartridge revolver. The RD1851U is also available with the proper Naval Battle scene engraving found on the original cylinder. To overcome the larger bore of the original barrel, it is recommended that you use either hollow based bullets or heeled type bullets.
(If, after installation, you are unsure of the fit, please take you revolver to a competent gunsmith or contact R & D Gun Shop to make sure you have the cylinder installed correctly.)
