R3M breech swap LEAK
I would love to contact the manufacture but I’ll feel more comfortable asking here. I was lucky enough to find a R3M to swap out for my R3 .22. After completing the swap I noticed a puff of air hit me in the eye after I shot. Hmmmm! So I thought the o ring might of slipped (pic below).

So I disassembled it and added a light lube so it can stick and the same problem persists. I’ve had a gentleman on the forums try and walk me through it but were both bummed out at this point 🙁

Just avoid the headaches and make sure you’re using metric keys 🙂 Man Rob, you’re scaring me. Either you have great memory or you’re taking notes with cut out magazine letters.
