The dovetail block is used to mount the William Malcolm short and long scopes. It fits into the existing dovetail on your rifle.

You may need a different sized dovetail block for your rifle if you are using any of the following mounts:

Henry Golden Boy .22 Mount (HGB22MT)
Winchester 73-76 Mount (W7376MT)
Winchester 1885 Mount (W1885MT)
Winchester 92/94 Side Mount (W9294MT)
Sharps Side Mount (SHSMT)
Round Barrel Offset Mount (RBOSMT)

Available sizes - 3/8" (DB0375), 1/2" (DB0500), and 5/8" (DB0625).

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 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.

If you are planning to sight the Wm. Malcolm 6X 30" Telescopic Sight at 100 yards, you will need to use the higher front ring. This will prevent the rear mount from running out of elevation when shooting 100 yards.

The standard height front ring for the Wm. Malcolm 6X 30" Telescopic sight is designed to be zeroed at 200 yards.

This mount set is to mount either the 3X 17” or 6X 18” Malcolm Short Telescopic Sight onto either a Winchester 92 or 94 - Top Ejection Rifle.

The two-piece round barrel off-set mount is designed for Malcolm 6X Long scope on round-barrel percussion sharps rifle, Volunteer/Whitworth, or other similar Muzzleloading rifles.

The mount moves the scope 1/4" to the left to clear the hammer.

You will need to use the standard 3/8" dovetail block to lock in the offset heavy duty base.

This mounting kit is only designed to be used with the Wm. Malcolm 6X Long Telescopic Sight. The set includes both the front mount adapter and the rear off-set heavy-duty base.

There are two sizes for the front barrel ring. The standard size is for a barrel with an outer diameter of around 0.825". The larger size is for a barrel with an outer diameter of around 0.875".

For most round barrel black powder cartridge rifles, the standard size will work.

Precision minded shooters looking to maximize the long range accuracy of the Malcolm 6X Long scope need a reliable and repeatable method to consistently adjust the elevation.

Due to the original design of the long scope, you would need to manually loosen and move the scope up or down in the rear mount to change the point of impact. With access to only a vernier scale on the rear mount, this method of adjustment is not consistent and is subject to human error.

With the Fine Elevation Adjustment Set installed, the shooter can simply turn the knurled thumbscrew to vertically adjust the point of impact. Rotating the screw clockwise will move the point of impact upwards. Rotating the screw counterclockwise will move the point of impact downwards.

For fine elevation adjustment of standard 30" Malcolm Scope M634MT mount.

The Sharps Side Mount Set is a two-piece mount for the Malcolm 3X and 6X short scopes.

If you’re looking to mount a Malcolm 6X long scope on your rifle without drilling and tapping or if you’re looking to shoot hot loads with heavy bullets with your Malcolm scope, you’re in the right place.

The Malcolm Sliding Mount indexes into the front and rear sight dovetails on the rifle. After each shot, the scope will slide forward in the mounts, which reduces the recoil energy travelling through the mounts. The shooter will need to pull the scope back in to “battery” after each shot.

The Malcolm Sliding Mount has several base plates to accommodate for various front and rear dovetail sizes. Be sure to select the appropriate base size for your rifle.

Specially designed for Vintage Sniper Competition, the new Malcolm micrometer mounts give you precise adjustment clicks to clean targets at 600 yards.

The Malcolm Vintage Sniper Competition mounts eliminate virtually all backlash between clicks.

Compatible with all 3/4" externally adjusted rifle scopes. The Malcolm VSC Mounts fasten on to crescent cut scope blocks.

To get 1/4 MOA adjustments, the front and rear mounts will need to be spaced 7.250" from center to center.
