Leapers Steel Rings
Leapers UTG Steel Picatinny Rifle Scope Mount Rings - 30mm MEDIUM RSW3154
Pair - 2 rings supplied
Upper and lower ring portions precision machined from one solid block of steel to strict tolerances for optimal fit
Heat treated QPQ nitride matte black finish for strength and added weather and wear resistance
Progressively machined for a precise inner ring diameter to achieve optimal tube alignment; grooved inner surface guarantees tube retention
Radiused edges and corners prevent snagging, scratching, or tearing of other gear and give easy access to scope windage and elevation turrets
Locking Torx screws and square-shaped integral recoil stop for a secure zero hold
2 piece ring set, each equipped with 4 top Torx screws; mounting base designed to fit on MIL-STD-1913 rail platform
Includes a T15 Torx wrench for easy fitting '
30mm Tube -
- Ring is 30mm diameter.
- To suit scopes with 30mm diameter tubes.
Medium Profile Height -
- 15mm base to bottom of ring "Saddle" and 30mm center height.
- Suit scopes with UPTO maximum 59mm OUTER objective diameter i.e., not the actual lens size.
- In practice this means in most cases scopes upto approx. 44mm lens when on a flat base.
- However if base is raised or end of scope will be over barrel with more space then larger lens scopes may be used.
- This is down to the user to determine we can only give broad guidelines.
- See scope clearance guide at bottom of page.
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 1" diameter body tube diameter this would mean deducting 12.7mm and 15mm for scopes with a 30mm diameter body tube.
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 'C' dimension that is shown above.
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 -
- A 44mm objective lens scope is measured and found to have an outer case measurement of 51mm.
- 51 divided by 2 = 25.5.
- 30mm scope so deduct 15mm = 10.5mm
- So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 10.5mm or else it will ground out on the rifle body.
Calculating your rifle scopes clearance in this way does assume the base is basic flat, not raised above or below your rifles barrel. 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.
Base fit - Weaver/Picatinny base -
- For base rails that look like the one pictured below (base rail NOT included).
- 20-22mm wide with horizontal slots.
- May vary in length and be 2 smaller sections on some rifles.
- If you do not have a base that looks similar to this, and have for example, an 11mm wide dovetail groove then the mounts can only be made to fit by also purchasing an adapter.
- Please ask us if unsure.
