Quick release mounts

[CDM5]

I'm after 2 or 3 quick release mounts for swapping between night vision and day scopes. Return to zero is important.

Is there anything that will fit the bill that won't cost the earth? 30mm.

Leupold QRW work well. I use on my 338 that won't fit in the safe with the scope, so comes off everytime, and return to zero is spot on.

I've had good results with Warne Tactical QD mounts but I think they were around £80 a pair.

I have both Leupold and Warne QRW rings on two of my rifles, both return to about 1/2" of the original zero if removed and replaced so acceptable for short range but no where near as close as my Ziegler mounts that are on another rifle.
You have to be aware that the levers can move and release if for instance the rifle is carried in the back of a truck so they aren't fool proof. The levers also stick out slightly and can result in catching on the lining of your gun slip. Before anyone mentions it, yes I do align the levers so that they are as unobtrusive and protected from knocking as possible.
I think that if I were buying similar rings again I would purchase the type that require the use of a spanner to release the rings rather than the hand lever type.
