Wondering how you go about breaking down a Hunting Master RS. I was lucky enough to come across one of these beauties, but its having trouble holding air above 2500PSI. Instead of sending it off to Will (for now), I want to try my hand at replacing the orings and such. It didn't come with a manual, and there's not much on the interwebs as to how go about dismantling it. Can anyone shine some light? Thanks all very much!

Hello PaulGood the hear that the RS is now in your handsSorry to hear about the leaks, but I suppose they are to be expected in a 20+/- year old rifleDo you know where it is leaking from?After repairing the fill assembly on mine, the next leak discovered is most likely via the valve.I've been staring at the works also trying to figure out the best way to tear it down.As far as a manual is concerned.I got a hard copy via AZ in SC via the importer under the conditions that I would not reproduce it.Try contacting Davis Scweshinger at Air Rifle Specialists130 Holden RdPine City, NY 14871607 734-734607 732-3261ars@stny.rr.com (untried by me)The manual covers the AR6, RS, & AR6 pistolThere is a parts schematic (AR6) but no pats listHope this helpsEd

I asked Davis for a manual, so I'm just waiting for him to get back to me. I'm going to assume that the leak is possibly in the same area as yours. Unfortunately, it also appears to be the one area I can't seem to access. A small note: when I first tried firing the rifle (thank you for the Sumatra probe tip, it works wonderfully!), there was no air being released. Upon further inspection, it appears that the little rubber/plastic hammerstop was impeding the hammer strike. I removed it, and I was able to get the rifle to fire. The hammer pin is getting pretty beat up from the metal-to-metal contact, so I think I'm going to shave that plastic piece down about 3-4mm and then reinsert it to save the hammer pin.
Hmm...interesting! Great tips on the hydro shop and the valve. The seller sent me some extra valves, so I replaced the original one in the rifle. Of course, those valves are probably as old as the gun, so maybe it's got me going in circles. I wonder if a PEEK valve would be worthwhile? FWIW, I did seal the valve end with the finger from a rubber glove. No change in how it looked. It seemed like the rubber glove on the gauge side was a little more poofy after a couple of days, but I can't remember if I squeezed out all the air. It's a bit more challenging to seal that side too, so I dunno if some air was leaking past the duct tape. Next tear down I'll snap up some pics for you.
noted, rkr...thanks for the tip! I can't say that making one is at my skill level, but maybe I can try? I'd be going off of eyeball measurements.
Hmm...that's encouraging. Thanks, rkr! I have a couple of extra poppets, so maybe I'll try and redo the surface on them. Side note: is it difficult to change out the hammer spring? The HM2 hammer spring is noticeably softer than the hammer spring from the RS. I'm wondering if I can source a stiffer hammer spring for the HM2; that would probably increase my FPE. I've tried switching out trigger assemblies (since they seem very similar), but the RS assembly doesn't advance the mag.
