Uragan singleshot magazine

This is a singleshot magazine for a uragan 3 in .25 with the hinge on the right instead of on the left.
.30 works too; I just drilled it out a bit, it's not an issue and allowed me to size some slugs perfectly this way.
Same for some oversize .25 I have.

I've got a bunch of these printed for specific pellet/slug.

In the hinge there is a recess to drop a oring in, this allows to center and better hold pellets or slugs even further.

This also works on other uragans and agt air rifles.
