View Full Version : Chassis scope mounting height

I have noticed in a number of photos that many folks using chassis systems mount their scopes higher than they would with a factory stock. Often times in an AR style / height, 1.5", mount. Is this the norm? Are the ergonomics or a chassis system conducive to a higher mounted scope?

Depends what model chasis you have. Xlr evolution you need to be high to clear the forearm. My mcree chasis rifles are mounted tight to barrel. Maybe 1/16-1/8" off

A lot of chassis systems do not have any drop at the comb like a typical stock would so the extra ring height is need to bring the center line of the scope into a useable range for most folks.

Some of the chassis that have a front tube around the barrel need taller rings for the scope's objective bell to clear.

On the other hand some chassis like the HS3 let me mount the scope on low rings.

I have a XLR Element on the way so I think I should be good with the low ring set up I currently have.

Just keep it as low as possible if you are shooting long range.

Don't forget that if you use a 20 moa rail, the objective gets closer to the barrel/hand guard. Then adding a sun shade makes it even closer in that case.

I am running a nightforce 20 moa base with nightforce high rings (0.535") with an XLR Carbon chassis and a 50mm Leupold Mk4 and 2.5" sun shade. The sun shade is so close to the hand guard that I can't use a flip-up front cover. I am thinking about moving to Extreme high (0.910") for better position on the comb
