Good evening. So I've just acquired a model 6 pistol in pretty good condition, circa may 1973. The pistol has seen very very little use over the year, but it's in need a fresh set of seals(piston seal, bumper and breach seal). Its got the GISS twin piston arraignment. All the seals are available from john knibbs. The thing is, I've never stripped one of these and I feel it might have a certain "method" to put it back together, PROPERLY!!??? Has anyone had any experience here? Any advice? Anyone that's a buff with these that wouldn't mind doing the job for me(I'd pay of course)?? If I dont get anywhere here I might even sell it on to someone willing to do the work.
