Hi,
New to the sight, besides a couple of purchases. A few months ago I decided to give service rifle a try, bought a white oak a4 service rifle upper with mk7 rail , the giessele mount you’re asking about, and the hi lux scope. Great setup btw. The mount Is rock solid. Have only had the woa upper to the range once to zero and test it at 200y. I’ve since taking it off, turns out I’m probably not going to do any sr competition, and put it on my carbine for a couple hundred rounds. Its still tight, thumbs up for giessele.
