Nikko Steel Lok QD rings
Nikko Steel Lok Quick Detach, Weaver/Picatinny base Mount Rings - Extra Low height 30mm tube scopes
Nikko Steel Lok Quick Release Quick Detach Weaver/Picatinny base Scope Mount Rings - for 30mm tube, Extra Low height profile
Quick release - Thumb operated quick detach levers for easy removal and re-fitting to original position - no loss of zero
0.175" - 4.5mm base to bottom of ring equates to maximum scope outer objective casing diameter of 39mm if on a flat base - Most scope outer casings add 5-12mm to the lens size (depending on things like if it is an AO scope, use of flip up caps etc) so these will fit scopes approximately with lens sizes upto 27-34mm depending on the scope outer case thickness.
See Clearance calculation guide below for more info on fitting thresholds.
Nikko call these low profile mounts but we would describe them as extra low height when compared to other mount rings - low are more normally around 8mm saddle height.
Extra low are rings are excellent for getting a very tight to base fit on small objective scopes or for lowering larger scopes fitted on raised bases.

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 - the measure from base of mount to bottom of the ring - the saddle dimension for these is 4.5mm - very small
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.
Worked Example -
- A scope has an outer case measurement of 36mm.
- 36 divided by 2 = 18.
- 18 minus 15 = 3mm
- So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 3mm or else it will ground out on the rifle body.
- So these ones with 4.5mm will be a great precise fit.
Calculating your rifle scopes clearance in this way does assume your dovetail or base is 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.
