Compatible with my hk .22lr mp5 pistol - NcSTAR MP5/HK Claw Scope Mount / Gen2

I was able to fit this optic mount onto my .22lr MP5 pistol without any issues. First, remove the pin at the front of the handguard so the hanguard comes off completely. Next, loosen both screws on the optic mount to allow as much slack as possible in the claws. Finally, wiggle the mount backwards (from the barrel) into position gently. It's a very tight fit, but you won't scratch anything if you're patient. I would recommend this item.
