Ok so i have a Tanaka M700, and the mag with it had a cracked O-ring on the internal Gas Retainer, and i cant seem to find the size of that o-ring online. Does anyone know what type of O-ring will work the best? Any help will be really helpful.
Hey guys, I was wondering about an o-ring size in the Tanaka 31-round magazine. I don't know the name of the location, but it's the last o-ring before the gas comes out of the magazine. And perhaps even the o-ring right before that one. I've finally been able to seal off the rest of the magazine, and these are the last 2 I need before its finally completely fixed. Thanks in advance guys.
