Ideal for long range shooting with high powered air rifles / rifles. Adjustable for elevation and height.
- 30mm Diameter Body Tube
- Height adjustable saddle from 22.5-23.8mm
- MOA adjustable upto 45 MOA
- 9-11mm dovetail airgun/rimfire type bases
- Suit scopes upto around 60mm lens (see clearance guide below)
This allows you to adjust your point of impact on the mount (without having to pack it out), and before you make final aim adjustments with the scope’s own turrets.
They have two locking-screws - set in threaded holes above and opposite the base screws – and recessed adjuster grub screws. First fit the mounts and scope to the rifle in the usual way. A removable recoil arrestor pin is included.
To correct elevation loosen locking screws (A) on front and rear mount using 2.5mm allen key. Turn adjuster screw (B) clockwise to lift rear of scope using 2mm allen key (¼ turn = approx 22mm at 25 yards). Retighten locking screws (A) FIRMLY. To lower rear of scope undo locking screws (A), push down on top of rear mount and turn adjuster screw (B) anti-clockwise as required. Retighten locking screws FIRMLY.
2 PIECE ADJUSTABLE
A = 22.5-23.8mm saddle (Height from where the ring base touches rail to bottom of scope ring)
B = 21mm long
Weight = 119g
NOTE: Both front and rear mount adjusters can be used to lift scope evenly if required.Maximum adjustment is 2 turns which = 1.3mm of full adjustment
The way you calculate the clearance is by halving the overall OUTSIDE diameter of your rifle scopes objective lens and then deducting half the rifle scopes body tube diameter.
For scopes with a 30mm diameter body tube diameter this would mean deducting 15mm.
Note we say OUTSIDE diameter - this means NOT the lens diameter, you need to measure the whole outer casing diameter.
The result gives you the minimum "saddle" dimension required - the measure from base of mount to bottom of the ring.
The amount the saddle dimension is greater than the figure you have calculated is the amount of clearance your scopes objective will be clear of your rifles body.
The saddle on these mounts is 22.5mm at lowest adjustment
So in this example, we have 22.5mm to use, so have a minimum clearance of 2.5mm
- A 60mm objective lens scope is measured and found to have an outer case measurement of 70mm.
- 70 divided by 2 = 35
- 30mm tube scope so deduct 15mm = 20mm
- So the mount must have a measure (bottom of mount to bottom of the ring) greater than 20mm or else it will ground out on the rifle body.
Calculating your rifle scopes clearance in this way assumes the base is a regular flat base. Some rifles with high or adjustable cheek pieces may require higher scope mounts or risers so that your eye is in line with the rifle scope and your head is kept in an upright comfortable position.
