Tuning Help ID this regulator

[mcoulter]

This came out of a used (pretty worked over, actually...) Air Arms MPR with a longer than normal air tube.

It has been marked with 120. I really wanted to drop the regulator pressure, but I could not get the knurled part to turn.

I dont know whos reg that is but I am not sure you want to turn the knurled part for adjusting. I would think the brass piece would be what adjusted the reg setting like on a huma reg. The pic of the top isnt clear enough to see what that brass piece looks like.

Thanks. Yeah, there didn't seem to be any way to get a bite on the brass part to turn it.

Oh the markings (line on face and groove on knurled part) makes me think it should turn though...
