Converting the Past
into the Present

The original Howell Arms Cylinders offer simplicity in converting your favorite steel framed percussion revolver to fire cartridges. Simply remove the percussion cylinder and replace it with one of our cylinders and the revolver is complete.

Reloading the cylinder is simple. Remove it from the revolver, take off the back plate, replacing the empty cartridges with the new ones, then reassemble the revolver.

The cylinders and back plates are made from Certified 4150 grade steel/416 Stainless steel, insuring strength and durability. All models of our original series conversion cylinders are designed for use with either smokeless “Cowboy” ammunition or Black powder ammunition that should not exceed 850 FPS or 12,000 psi.

ALL Conversion cylinders must be used with STEEL FRAMED revolvers with the exception of the 1851/1860-22LR conversion kit!

The conversion cylinder gives the owner two revolvers in one!
