10-shot-limiter for Black Dog .22 Magazines

This is a limiter for longer black dog .22 magazines for the ar15 cz v22 changing system.
It reduces the loadable bullets to 10, which is required in many countries to harass the sportive shooters. Put in with flap to back.
Yes, one could just buy the small ones, but there was a time they were not available and one doesnt want to throw them away.

UPDATE: Thing is now useless because of new harassment laws in nutsie germany. Condolences to my german friends.
