I purchased the Discovery HI 4-14x44SF SRF FFP MOA directly from Discovery (ALIEXPRESS), on sale with their 26% off mobile deal. Oredered on 7/2 arrived 7/11. Love the gunmetal grey finish, very nice scope. Haven't mounted it yet, it came with free rings but they sent Picatnny instead of the...

William (groundhog) Looks like you have machining experience, have you considered machining the connecting rod to accept bearings? In a video on YouTube a fellow Brit had a problem with his YH and was showing a close up of the con-rod and I not only noticed there were no bearings at either end...

Finally, an answer to something I was planning on doing, using my TUXING compressor as a booster pump, thanks prfssrlee. However, the TUXING is different to the YH in that the interconnects are contained inside the coolant chamber so hopefully that will help keep the temperatures in check. In...

$172.00 + $16.34 tax, free delivery, Nov 25th 2017 from Walmart. Already had one but for that price I just could not resist. I have a Huma regulator to go in it but I still haven't set up my shooting range outside, I want to compare it the un-regulated one. Before I can do that I need an...

Interesting results, between valve, hammer, trigger and bottle regulator mods, what a fun air rifle this looks like it's going to be. Being a consummate "tinkerer" I'm looking forward to getting one of these and the enjoyment of modifying it. I wonder what the shot count on the stock UK version...


Did it fix the problem?

I found this picture online; It looks like it presses together with o-rings at thetop and bottom of each stainless steel tube as well as the gold anodized aluminum top and bottom. Should be still under warranty, I'd contact the seller and have them send you a new head. Clean the sump out...

It sounds like one of the seals of a high pressure transfer tube is blowing water past the first stage piston rings. I just re-assembled mine after putting in a new DPST switch, I looke to try to see how the second stage was held together and the only thing that seems to do that are the four...

The temp probe was 35~50C with 5 gallons of water and ice. The first stage pot read 60~65C with non-contact IR thermometer. I filled in stages, 100 BAR, 180 BAR, 260 BAR, 300 BAR with about 20 minute breaks to allow the motor and crankcase to cool down, and 5 minute interval drain purges. It...

I just received my Tuxing compressor. The internal styro-foam was beat up and my case scratched by loose bags of parts. This item should really have been double boxed. It looks like the nut holding the circuit breaker came loose and exited the box through one of the holes it had in it, the...
