leaky mags
« on: February 04, 2007, 01:36:28 PM »
i had some leaky pistol mags for an HFC M190 and found an easy fix thats free. I hope this helps for anyone who has a leaky mag (or maybe people already figured this out before me :-? )

There are two pins that hold the base onto the gas chamber. punch them out and pull off the base. Theres a square shaped rubber ring (o-ring) on the inside of the base. The bottom of the gas chamber pressed on the rubber seal and compressed it, over time, this caused a leak out of the base, as opposed to the filler nozzle. Simply take off the rubber seal and put it on inside out. the seal will protrude from the lip wherer it rests. put the base back on, leak fixed.

another mag had a leak in the filler nozzle, i performed the same treatment to the o-ring on the top side of the filler nozzle. problem solved. :) hope this helps

I do this with o-rings at work all the time. Just know that the next time they will need to be replaced.

add silicon spray or gel to help rejuvenate the seal when you put it back on, it works wonders to keep it pliable.

yeah i thought about that. ill probably end up swaping the seals out all together next time they leak.

Where do you get O-Rings from?  Is it economical to get new O-Rings, or would it be cheaper to buy a mag?
(I don't mean to sound critical, I honestly don't know.  I haven't purchased a GBB yet but I think I will before LC so I want to learn)

a new mag runs about $30 so new o-rings when the ones u have totally crap out is an excellent idea! another excelent idea, is to keep some gas in the mags at all times. like a half a second's fill. this keeps the o-rings plump and moist (theres a little lube mixed in with the green gas). this will significantly prolong the life of the o-rings. of course, to put off buying o-rings even longer, you can do what i did, and turn the existing ones inside out when they start leaking
