Designed to mount an RMR at a 45 degree angle as a secondary sight next to your primary optic which makes it ideal for close range Shooting.
The mount features the ability to attach to either the right or left side of the weapon.
Fits any Picatinny rail
Yes, and an offset mount is one clean way to do it. Keep your magnified scope on top and put a small RMR-footprint sight on the PM03 at 45 degrees. You roll the rifle to switch, so both sights stay zeroed and ready.
Where your state allows night predator hunting, yes. A mini thermal on the PM03 gives you a close-range option when a coyote rushes the call, while your main scope handles the longer shots. Check your state's rules on night hunting and lights first.
