Other Reximex RPA grip and mag

[chfj]

Just picked up a Reximex RPA in .177 and I am impressed!
Does anyone know of a USA source for the 14 round .117 rifle magazine?
It comes with two pistol mags and one rifle mag and I'd like to pick up a couple of additional ones.

This is 25 yards from the bench with red dot. Ammo is JSB 7.33 pellet.

That’s a nice group with a red dot! Wonder what it could do with a scope? Maybe a compact 4-16 or so from the bench.
Congrats!
