Out of all of my guns...

[MikeVV]

My Weihrauch HW100, Bullpup, Carbine has developed a major leak. It's about two years old.
I replaced the o-rings at the valve, behind the air cylinder. No difference. Waiting for the cylinder o-rings. I didn't get those in the first o-ring kit.

Damn, was having pretty good luck, with, non-leaking guns. Hmm forgot my RTI Prophet that leaked at the rear fitting. Not leaking anymore.

Mike, all pcp's sooner or later will leak. O'rings deteriorate over time. It's the nature of the beast.

Yep, there are two kinds of PCP airguns: Those that have leaked, and those that will.

Yeah, fully understand, and have been waiting. Just wasn't looking forward to a rebuild just yet. Seems a bit early in its life for new seals.

How old is it? These guns don’t have many orings so I agree that it shouldn’t develop leaks earlier on. How are parts availability? For it?

As in my original post, I've owned it about two years. How long it may have sat on a shelf, for a full "age" count, don't know.
Haven't needed any factory parts until now, so other than that, don't know. I haven't gone looking for any sort of custom parts other than changing the suppressor.
I understand that Bagnall & Kirkwood has full o-ring kits.
It's been a nice shooter until the other day, when I picked it up to do some shooting and found the pressure gauge needle at 0.
It's got a great magazine...holds 14 rounds and...NO...movable plastic covers, no springs ! All air gun magazines need to be designed this way...simple, unbreakable.

Agree about the magazine. I have an HW100 carbine, best mag system I've ever seen. Don't know if the BP has the same mag advance system, but in the rifle it is a solid steel gear driven design. And if you are in a hunting situation, the auto advance is disabled with a simple slide button. Then you have the perfect anti-double load, just manually advance the mag for the each shot, easily rotated with one finger.
I can't offer any information on your leak. My rifle is 3 years old, and no leaks yet. I'm not sure that I would tackle a complete reseal job myself, but at some point it will need to be done.

I always look at it like this. Great guns just don’t require a guy to be taking it apart to do mods or improvements. When you finally get a leak with a good gun, it’s the forced opportunity to take a look inside the gun and see just how well it’s built.
