Blaster

.22LR
How many rounds has anyone fired through a JM pro , with out cleaning ?Before it starts to malfunction? I clean my JM pro after each outting. Just curious to see if anyone has tried this.
 
No, I haven't tried that, but I would be interested in seeing about where to start worrying, but could still be largely gun specific too.

My Walther P22 will go for over 850 rounds suppressed. Just as an example, and others can't seem to make it a few magazines without choking.
 
Over 2000 with an SBE Precision Products piston, and Or3gun spacer.

I generally clean after each outing. I, along with two enthusiastic friends, ran about 475 mixed rounds of (mostly) Winchester white box, and Remington 00 buck (~125 rounds) in 40 minutes. No issues. I have the NiBo JM Pro piston and the OR3Gun spacer tube.
