Anyone using Scalarworks LEAP Mount for oldie Aimpoint CompM4? I have had LaRue QD for years, but really like Scalarworks (weight and design) mounts. Scalarworks specify 1.57 " height for one third co-witness; LaRue specs indicate 1.725" for one third co-witness. 
I tried one. It looked nice.
I’d stay with the 1.7" if you’re used to it. I don’t think an extra .03" is going to be any better than absolute.
I run the Lower Third version on my Pro and it is good to go in my book. It is lightweight and locks up solid on the rail. It was between it and the Geissele Pro mount and almost all of my RDS sights sit on Scalarworks mounts, so I decided to continue that trend, as they are solid mounts and I like the system they use to mount to the rail. I wish they would do some 1.93 height mounts though.
I have an Aimpoint Micro on a Scalar Works mount. It’s solid, light and hold zero. I would purchase another with no hesitation.
