AvidShooter, member, from AZ, United States, asked on January 21, 2024

Will the 39mm spacer, LRP mount work with the Unity Tactical Aimpoint Magnifier Flip-To-Center Mount, Black, FST-MAPB?

Unfortunately not,

The unity FAST magnifier flip mounts are made to work with the FAST optic mount as their heights (2.26") is higher than the 39mm mounts.

What is max distance for this model?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on September 19, 2022

The Aimpoint CompM5 Red Dot Reflex Sight is a non magnified red dot sight. So when using it the target you will appear the same size as if viewing it with the naked eye for a given distance.

Will this fit an RS Regulate AKML aimpoint mount?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on March 07, 2022

The manufacturer of the RS Regulate AKML Aimpoint mount doesn't specify if the Aimpoint CompM5 Red Dot Reflex Sight will fit that mount. I recommend contacting the manufacturer to confirm compatibility.
