Leapers UTG 30mm Medium Height 34mm Offset Picatinny Scope Mount Ring AIR31834
Designed to provide an offset from the base to give extra compensation distance to the eye relief in addition to what the mounting rail allows normally.
Rail Type: Picatinny - 20mm width. NOT 9-11mm air rifle/rimfire dovetail. To fit such needs adapter base. Please ask if unsure.
Precision CNC machined from aircraft grade aluminum and finished in a matte black anodize
Significant lightening cuts to massively reduce weight without compromising durability
Radiused edges and corners to prevent snagging, scratching, or tearing of other gear and for effortless access to scope windage and elevation turrets
Single mount utilizes locking Torx screws and square-shaped integral recoil stops for a secure zero hold
- 18mm saddle height
- 34mm offset distance

Scope size fitting considerations:
Suit scopes with outer objective casing diameter maximum size 65mm - That equals about a maximum 52mm lens size depending on the scope. If unsure please check measures before you order and see Clearance Guide below to learn how to assess if they are the right height for you and if so how much clearance you will have over the base
Calculating scope to rifle body clearance
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 this means 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 18mm saddle.
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 18mm
- A scope has an outer case measurement of 58
- 58 divided by 2 = 29mm.
- 30mm tube scope so deduct 15mm from 30mm = 14mm
- So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 14mm or else it will ground out on the rifle body.
- So in this case with 18mm there will be 4mm clearance, a nice fit.
Calculating your rifle scopes clearance in this way does assume your base is not raised above or below your rifles barrel. Many weaver bases are raised to some degree which may well affect the sizing consideration.
Note 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.
