Makes the flight path pretty level out to 125 yds.
All of the cantilever scope mounts I have (and 2 others I mounted for friends) on my AR's put center of scope tube at 2.75". This goes for the Vortex one, Burris PEPR, GGG mount, and a cheapo Vortex clone from Amazon. A 45yrd zero has me within 2" high/low from 10 yards out to 220yrds.
Oldhunter - Take your measurements of when you get your scope mounted up, along with velocity and bullet BC... and use a simple ballistic calculator to get a ballpark estimate to find your preferred mpbr.
