One of my magazines for the G19 is having problems... the shots are extremely weak, and sometimes spews gas. I have notices that the rubber (part that is supposed to seal to the blowback chamber) has two tiny stripes in it.
My spare mag which does not yet have these two stripes on the sealing rubber (but is showing slight wear as well) works just fine.
I have searched for the spare part (part 209), but all the major airsoft retailers are either out of stock, or do not stock the item at all.
My question is, how would i got about making the rubber fully sealing again?
Any ideas appreciated. If something doesn't make sense, please ask.
