Sportsmatch ATP65 1" scope ring, Elevation and Windage Adjustable 9-11mm dovetail base Rifle Scope Mount Rings
 
Ideal for long range shooting with high powered air rifles / rifles.

Designed for 1 inch scopes and 9.5-11mm dovetails, this ingenious design allows for full adjustment of the scope to zero (whilst the scope is attached to the rifle), purely by adjusting the MOUNTS – with just the final tweaks on the scopes turrets.

 
  • 1 inch Diameter Body Tube
  • 9-11mm dovetail airgun/rimfire type bases
  • Adjustable Extra High profile - Height adjustable saddle from 26.5-29mm
  • Elevation MOA adjustable upto 75 MOA. 1/4 turn = 30mm at 25m
  • Lateral windage adjusts 40mm at 25m per 1/4 adjust screw turn. Perfect for dovetail centering
  • Suit scopes from 50mm to over 60mm lens (see clearance guide below)
  • Does not include arrestor pin
  • Beautifully engineered - a sound investment.
Locking screws include a anti vibration coating which locate into a hardened steel spigot to ensure no loss of zero. Absorbs even the hardest recoil. Development tested on a 25lb/ft springer shoulder buster.

With this mount, the scope can be virtually zeroed by adjusting the mounts alone, and only using the scope’s own turrets to fine tweak at the end of the process.

This means that the optics can be ‘centred’ , which sees the turrets set to their mid point of adjustment, prior to the mounts being used to zero the impact point.

By centring the optics, the scopes internal mechanism is under minimal stress, rather than being wound too far in one direction.

A further benefit of this mount concerns the classic air rifle zeroing scenario where the scope has run out of adjustment on the turrets (usually too low), yet the impact point is still several inches from zero. Barrel droop can be a common problem, which leads to this predicament, as can scopes that simply have too limited a range of internal adjustment; requiring a near perfect set-up on the rifles action, to allow the zero to be set at all.

 

2 PIECE ADJUSTABLE
A = 26.5-29mm saddle (Height from where the ring base touches rail to bottom of scope ring)
B = 21mm long
Weight = 116g



Each mount has a movable top half which can be adjusted within its base. The mounts are locked onto the guns rails, and the locking screws must then be slackened on BOTH mounts, to allow for slight movement of both when one is adjusted. The scope can then be gently set into position.

Elevation can be adjusted via a small screw in the foot of the (rear) mount, using a special ball-headed Allen key - so shaped as to allow for easier access into awkward areas. This elevation adjustment in the mount is apparently a unique feature; along with the fact that the scope sight line height can effectively be set as previously stated, when both mounts are simultaneously raised.

Windage is adjusted via the same slackening process, followed by the side screws. Once the zero is close (say within an inch, fine adjustment can obviously be set with the scope turrets if you prefer.



 
Clearance guide

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 1 inch diameter body tube diameter this would mean deducting 12.5mm.

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
26.5mm at lowest adjustment

Example -

  1. A 50mm AO objective lens scope is measured and found to have an outer case measurement of 64mm.
  2. 64 divided by 2 = 32
  3. 1 inch tube scope so deduct 12.5mm = 19.5mm
  4. So the mount must have a measure (bottom of mount to bottom of the ring) greater than 19.5mm or else it will ground out on the rifle body.
So in this example, we have 26mm to use, so have a minimum clearance of 6.5mm which is a good easy fit that also allows for no hassle use of flip up caps

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.
