Airsoft Canada - View Single Post - TM USP (Full Size) O-Ring Replacement

Ourindar · November 1st, 2019, 20:07

Hey folks,

I bought a Tokyo Marui USP a while ago, and sadly the o-rings in the magazines seem to have gone (the mags leak gas visibly around the edges of the bottom).

I grabbed a set of replacements from Eagle6. They're a bit thicker than the stock ones (by design). I'm having a lot of difficulty installing them - I can replace the o-ring itself just fine, but putting the base back in the magazine is proving impossible. I just can't seem to get the pinholes at the bottom to line up right.

Has anyone done this or have any tips?
