LeatherWood Off-Set Plate with 1/2in 60 Degree Base gives the scope plenty of hammer clearance, yet does not have the scope setting so far off to the side that the shooter has to pull his or her head off of the butt stock to properly align their eye with the rear lens.
One problem the muzzleloading shooter and hunter runs into when trying to install a riflescope on a muzzleloader of very traditional "side-hammer" design is getting the scope off-set enough to insure that the hammer can still be drawn back to full cock - and that it does not hit the scope tube when the trigger is pulled. No one mount arrangement works well with all rifles. However, for the vast majority of those who shoot and hunt with a rifle of traditional styling, their rifle of choice is three-fourths of the time a percussion ignition rifle with an octagonal barrel.
For those rifle owners, Hi-Lux Optics now offers a simple set of off-set bases that gives the scope plenty of hammer clearance, yet does not have the scope setting so far off to the side that the shooter has to pull his or her head off of the butt stock to properly align their eye with the rear lens. Depending on the caliber, load and especially the amount of recoil produced, these Leatherwood bases can be attached to the top flat of an octagon barrel using either two or three screws. Three holes for attaching are pre-drilled on the plate.
The blocks are attached and one of the 1880s style Malcolm scopes can be easily slipped right on and tightened in place. (These come in 17" long 3x and 18" long 6x models.) Location of the bases on the barrel is determined by where the scope will need to set in order to provide the proper eye relief, which can be adjusted several inches forward or rearward by loosening the ring of the front Malcolm mount and sliding the scope in the direction it needs to go. Also, the simple design of the Leatherwood off-set bases allow them to be simply turned around and mounted with the blocks off-set in the other direction on left-handed rifles.
