Well so much for brand new BSA mk2 .....

I received my R10 mk2 in .22 from PA yesterday, and guess what? It leaks.

I had read on this forum about the leaks so questioned them ahead of time "No issues" they said. To be safe I paid for the 10 for $10 pre ship testing which supposedly checks for air retention. The test certificate claimed it was filled to 200 bar and held pressure. It arrived with about 70bar in it. On first fill, it had a slight but perceptible leak from the fill port area. I charged it to 200 bar (sure was a bunch of pumping!) and the leak sound had gone away. But this morning it was below 100bar.

Ugh.
 
Based on this thread, it seems that - contrary to PAs opinion - a lot of these NOS R10 mk2s have the same issue. If they send me another, it will probably either leak out of the box or develop a leak in short order. I'd be happier if they just paid for a seal kit and let me disassemble and fix the problem myself. Sounds like enough people have done it and the knowledge of what is probably to blame (gunked up regulator) is there.

So much for the 10 for $10 test.

Bummer. Yours should be a "special" complaint for upper management and you should start there.

In your particular case they certainly should pay all shipping , at the least.

You paid for the Premium Service, you need premium smhooz (sp) .



Orings should last 10 years. Several seem to have mention a green colored contaminate and as there all new it sounds like a factory contaminate.

The newer reg is certainly better than the original, really not bad rifles at all and at a good price. If anyone has a leaky one it is worth repair and should'nt need re-doing for a good 10+ years. There are also several very good tuners for these in the U.S. . IF you knew ahead they leaked and figured in professional repair cost it's still a decent value. Sure isnt fun not knowing up front tho. 

Could be worse, I know a fellow who got a "deal" on a new in the box Hill hand pump from a dealer. Trash from sitting too long and NO parts ever made for it. That dealer is now gone.



PA will take care of stuff but I still do feel for y'all who just wanted to use your new airgun.

I'm going the other way. It looks like five people in this thread have had the same issue, I would guess that even if you get one that doesn't leak out of the box, it might not be far from leaking? P.A. offered me a replacement but I just ordered a full seal kit from the U.K. At this point after all I've read on this thread I know I''d want to strip the replacement if I took it anyway with all the talk of green corrosion etc so I may as well keep this one, strip it and replace the seals. A kit for the rifle plus the regulator including shipping is about $30.




 
Hi Guys,



I see from these threads that many guys are getting guns that are not working/leaking. I would like to offer an alternative resolution. If any of you guys want to to get your guns fixed without going through the dealer, please call me (leave a message if necessary) I will try and help you fix your gun.

I was thinking, with this corrosion issue, perhaps some of the various ball bearings in the gun might need replacing too. Anyone know if BSA uses metric or imperial/SAE bearing balls? Also, hard chromed or stainless? I'd like to have them on hand in advance but I,m not stripping mine till the seals arrive from the UK, so I'm hoping someone who had to replace them knows?
 
I do not know for a fact but I think that the ball bearings are stainless. My R10 had the corrosion on the fill valve and the reg - the two spots that have the ball bearings. The spring that pushes on the fill valve bearing had quite a bit of the green crud on it yet both of the balls were pristine. This is why I think that they are stainless. I wouldn't worry about needing to replace them.
 
Best thing I can tell you is watch the XTX Air videos. That is what I did. With that said:

- Don't overtighten the pressure gauge because it can compress the sealing o-ring and cut off the air to the gauge.

- I left the reg at it's factory setting. You can disassemble without changing setting.

- The screws that hold the barrel in place are only accessible while disassembled, so now is the time to clean it.

- Pay attention to what the order and orientation of the baffles in the shroud are. I did find some corrosion on the springs in the baffle.
 
Well I paid the 10 for 10 and thought I’d gotten a good one, hope, turns out mine leaks. It held air for a week or so but I shot it today and refilled to about 230 bar, it was around the 2nd to last white hash mark on the bsa meter. A few hours later it’s gone down to the center mark. Can’t hear any hissing so it’s a slow leak but still a leak.

im undecided now, ship it back or try fixing it.
