I have a AA510xs, ultimate sporter in 177. It claps airgun silhouette targets on the no 3 setting. I might get 80 shots to a fill. Personally I like the 177. Like i said, it seems to be like a laser at 20 yards, and the chicken targets snap back like they were hit with lightning. I just...

I had the same thing on a new 510XS. It would leak down from 250 BAR. I read up on leaks in new 510s, and two o-rings that seal the cylinder to the receiver were at fault. So I had similar orings on hand, so I swapped them out. That reduced the leak considerably. I next ordered the...

As I said, I replaced the 2 cylinder orings with a touch smaller 2.5 x 22 buna n 70 orings. Looking at the bright side, it showed where the failure occurred, but I still had some overnight leaking. I ordered a bunch of orings for various rifles from orings and more, and the total was less...

Glad I bought a Bauer compressor. Scary to spend that cash, but unlimited air is great. Should have bought one sooner.

One link for the correct oring according to the manual. Like I said, the softer 70 durometer oring seems to be OK at this time. Those softer orings are available, but I have some in my stock anyway...

So I finally was able to contact Air Venturi. They wanted an original sales slip to initiate a repair. So I did not have that handy, so I thought it would be a good idea to disassemble, and see what I could see. The air rushing out of the barrel was due to the rifle not being cocked on...

I found that particular oring on Amazon. 50 for 5.49. https://www.amazon.com/uxcell-Rings-Nitrile-Rubber-Diameter/dp/B07D9P57S7/ref=sr_1_4?crid=JBAHNX964SH5&keywords=8x1.5+NBR+70&qid=1707795841&sprefix=8x1.5+nbr+70%2Caps%2C102&sr=8-4 I tried calling Air Venturi for support, but I guess they...

I did not fire it with the bolt open at any time. It was just filled up and sitting on the shooting bench. Then maybe 2 hours later it just blew. I was about 6 feet away and I was pretty surprised. Is it easy to get to that oring? I checked my kit, and I don't have one in that size.

So I have a 100 or so rounds through my S510 XS. As luck would have it, I hurt my back, so I could not shoot it for a few days. Since my back is better, I figure I can shoot it a bit tomorrow. So I topped off the cylinder to 210 bar, and have it sitting on the bench. About 2 hours later it...

I bought an Ultimate Sporter XS in 177. My primary use is shooting indoors at 10M to practice for smallbore silhouette. Anyway I immediately loaded up my favorite pellet, the JSB 10.3, and I could not hold the 9 ring. I was pretty shocked. I tried different power levels with mixed results...

Pyramyd has always done me good.

The gentleman that sold me the rifle actually included a Rowan single shot adapter. I also have a single shot sled that I got when I purchased the foster fill adapter. But, I kinda like the magazine loading. As a side I was shocked that it did not shoot the JSB 10.3 grain pellets well, and it...

Well I looked at it a bit, and saw the center screw was backed out a smidge. So I just tightened the center screw and it fit right in.

This seems weird. I just bought an Ultimate Sporter XS in 177. One magazine fits easy and works fine. The second magazine does not seem to lift the retaining latch. I tried the mags with and without pellets. One is butter smooth, the other won't raise that latch or go all the way in. Both...

Smart to fix it yourself. Mailing rifles is a crap shoot. Good luck.
