Got it! Thanks again.

Thanks! Are the screw threads that may need Loctite the ones on the little front cap, or the adjustment screw? I bought a couple two-pin security screwdriver bits to take the caps off, but haven't tried that yet. The air gun forum in England mentioned earlier has some photos where someone lightly re...

I've got the pressure gauge, aluminum & a shop to make the tester. All I need is time... Speaking of the little plastic seal on the front end of the piston: I assume they get chewed up a bit over time. Are those replaceable, or do you need to get the entire piston assembly? I haven't found any p...

Good to know! Thanks!

Even if the O-ring is "new", the green ones are probably polyurethane. This is because that has the best wear resistance. That said, they have a shelf life of 5 years, and (depending on the exact material) can stiffen over time. Once it gets mashed down, it may not be as much of an issue. ...

I worked on the LP10 that was acting up, starting by checking the velocity. I didn't see anything that would explain the +/- several inch elevation swings, but the velocity was quite low (around 147 m/sec, versus the recommended 155 to 160 m/sec. However, in 10 shots, I saw the velocity vary by abou...

I just got a PM from a new user ("Victorylap") with zero posts responding to my WTB ad. No info on the item he claims to have. He gave me a phone number, but I'm not even going to waste my time trying it. I already got scammed once on my WTB posting.

Lovely! Thank you!

That's the first drawing I've ever seen that shows the regulator internals. There are actually more parts than I expected, like the # 29.6 "Guiding sleeve".

Make sure the rear sight isn't bottomed out on the grip. You may have to do a little carving to fix it.

Information I have is that they are: 3 X 1.5mm Durometer 90 for the small one on the high pressure side Trade size (or "dash") 904 Durometer 70 for the one on the low pressure side. This is a US standard O-ring size. I'm surprised at the discrepancy in the size called out for the small one...

Update: Last evening, I examined the pistol, and nothing was obviously wrong. I did notice that the cylinder valve only opened with very little gap between the cylinder and the frame. It may be that the cylinder valve wasn’t opened fully. I put a different cylinder on it, and it appeared to work OK....

Thanks! I went to save it, and found I already have a copy...

Thanks! I was going nuts trying to find one for sale. Now that I have the part number, this place has them considerably cheaper: https://www.benke-sport.de/steyr-druckminderventil-pruefvorrichtung-lg-und-lp-36991 That price includes VAT. Without that, it works out to ~ $127 USD, which isn't too bad....

The college team I help coach has more extreme requirements. When we go to away matches at other schools and the National Championships, we need tools & supplies to keep 10 students' air pistols & .22 running smoothly over several days. The current Coaches' travel kit looks like this: Coach'...

Thanks for the responses! Another forum member PM'd me and said his pistol had the same sort of failure. His regulator valve had gotten gunked up (bad/moist air?), and he had to clean it. After that, it was fine. Both the green O-rings in the breech mechanism are there. The bigger one the bottom of ...

We were running a practice Final for the college pistol team I help coach, and our top shooter's LP10 started dropping shots well below the target. The sound of the shots was much too quiet. My first guess was low pressure, but the cylinder gauge read around 110 Bar. I popped it off and put it on ou...

The college team I help coach just sold sixteen of them to a large Junior Olympic program at a local club. We had six Tau-7 Juniors, and the smaller kids really prefer them to AP20's and some of the "kid" PCP pistols they have. I overhauled them all, and most of them still worked fine, des...

I have titanium firing pins in my competition AR-15s, because they are light enough that you won't get slam fires shooting ammo with sensitive match primers. Another downside of titanium is that if you get a pierced primer, the hot gases will eat the end of your expensive firing pin VERY quickly. Th...

The history of this rule has been beat to death in other threads. The short version is that an EU regulation originally meant to cover life vest cylinders (which are exposed to salt air & moisture) was written in a way that affects air gun cylinders. The ISSF rules were changed to meet the EU re...

If it's that windy, dry fire inside. Practicing shooting poorly won't help your technique. You will only get better at shooting poorly.
