More on Micro Clones and Mounts
Note that I use Aimpoint mounts only for these clones.
On the left is a Sig Romeo5 + Aimpoint Micro LRP Mount. On the right is a Holosun HS403GL + Aimpoint Low Mount.
Aimpoint states the optical height of the Micro LRP is 20mm. The non-QD Aimpoint Low Mount (newer square version) is 18mm. What I didn't notice in the past is the "body" of the Sig Romeo5 is also higher than the Holosun. I took a measurement when mounted on that rail and the Sig is 3mm higher (so 2mm from the mount and assume 1mm from the body).
