In anticipation of my new Falcon Menace 4.5-18 I decided to buy 30mm rings. I wanted quality rings that I could remove and replace without loss of zero (like my aimpoint ML3 on a Larue mount). I was wondering if anyone here had good experience with the QRW rings, sometimes I think I should have gone with Burris XTR or TPS rings. I did a forum search but didn't found actual reviews of the product. What about larue SPR mount? Is it good enough be able to switch from my R700 to my AR15; or that is a bad idea too.

Base plate is a EGW 0moa. Rifle is a Remingon 700 SPS .308 on a AICS chassis.
