I’ve had a couple of the same questions via private messages that I’ll answer here for others.
The Larue Mount is a quick disconnect low profile mount which attaches to any picatinny or weaver style rail or base, short or long. Easily take on and off and never lose zero. You can look the mount up on the Larue website. https://www.larue.com/products/larue-tactical-trijicon-rmr-mount-lt837/
The EGW mount is a solid non QD removable mount if you don’t plan to remove the SRO optic. It is a universal .670 radius mount that will fit several different guns. Listed below, I purchased it for a Winchester model 70. Rifle:
Remington 700, 722, 40x
Remington 783
Remington 710/770
Remington XP 100
Remington 4, 6, 7400, 7615 (Front Set Only, 8-40 Screws)
Savage Arms Centerfire Models
Winchester 70
If you are interested in the sight with only the Larue QD Mount let me know and I’m sure we can figure something out.
