Red Dot Mount Height for Marlin .357 Mag

[mryuezhang]

Hello everyone,

I'm trying to mount a red dot on my Marlin .357 Mag, which already has a Pic rail. I can't decide between a 22mm or 30mm QD mount. Does anyone know which one makes more sense?

Cheers

Standard/low Aimpoint micro mount works great.
Not sure what it measures.

I think that would depend on the size of the red dot and the height over bore. Are you trying to co-witness with iron sights and using a pistol mounted lower red dot or a larger red dot where co-witness is not possible on the rifles you are using?

I believe the low is 22mm and the medium (standard?) is 30mm

On the Marlin 1894, I found the drop in the comb just right for using the iron sites, and too low to get a proper cheek weld with even a fairly low mounted red dot; I had to add a cheek riser. A mount intended for an AR style modern sporting rifle will tend to sit too high and will be tough to get a proper cheek weld.

I would try the lowest mount you can get and try it out, see you it feels, but it may still too high for your comfort.

Lowest mount you have. That pic rail already adds height
