Wacutter;Nice write-up. One of my all time favorites.
Search "Yong Heng," "GX-CS Series," in archives for more information. 3.5 years with $272 Yong Heng, did replace leaky gauge and water pump. Pump my fault for pulling on wires removing from water bucket, new one $11. Again, not portable but easily fills SCBA tank for away missions. WMwow there is a lot to learn about compressors thank you I will look into the GX-CS4 I'm in Ontario so finding a AirSabre is the trick
My deadhead tests from new were a bit slow (35 sec). I removed the check valve and ran the compressor for 45 min, occasionally swabbing out the accumulation of gunk. When I put it back together, deadhead tests dropped to 28 sec. I cant wait to time my next bottle fill.I had a very slow fill issue with my GX CS4 taking more than 3 times as long to fill. When it got to around 2,000 PSI it was sucking canal water and struggling to the intended fill. I was about to give up troubleshooting it and after contacting GX customer service they replied back with a few instructions to correct my issue. And, it worked like a charm I am now filling faster than my original deadhead tests when I received the compressor. This is what GX responded to me with and I encourage you to also try these steps.
GX representative response to me via email:
"1) Hello please check if there is leaking carefully first. Include whole hose, bleed valve, burst disc and so on. It mainly was caused by leaking. It is easy to fix. keep the bleed valve tighten, watch pressure gauge and if it drops quickly? then it means it's leaking.
2) If there aren't any air leaks, another possibility, see if compressor runs hard when reaching to 200 Bar or 3,000 PSI? if yes, follow this video to run it for about 1 hour.
you can connect test plug, keep bleed valve tighten, excess grease or dirty will come out from check valve (under burst disc )
3) If still can not solve, water washing , follow this This should surely can solve the problem."
Step 3 above is what corrected my performance issues. Good luck.
I purchased the Maverick in .25 and love it for squirrel hunting. I have yet to have one get away when hit, they all have dropped dead on the spot. I think the .25 would fulfill your need.Looking to purchase a new squirrel / varmint gun , would a wild cat .25 or .30 be a good choice? Thanks
Tanks ain't that good looking.Today I cleaned up, mounted the scope to the correct clock position and set the eye relief. Interestingly the scope has numbered turrets, a resetable zero and zero stop system. All admirable features by today's standards much less something forty years old.
I'm anxiously waiting for the outside temps to reach the 30s so I zero and chronograph this beast. By beast I mean physical size and weight. This thing is a tank.

Ugh… nice thing. Sadly (or luckily, who would knowthanks
for the bubble level it goes with the trs rail from saber tactical
I no longer have the original M4 rail. I mounted the ST0088 from saber tactical It has the advantage of holding the barrel in place.

I got the .177 a while back and I love mine too
I do appreciate your response.PLEASE send that barrel back to Scout so Scout can send to Sub-Moa for a replacement. Simply put, that barrel should have never been installed in a gun. Rest assured that is not what Sub-Moa produces and many procedures have been put in-place to prevent this type of thing in the future.
Also, keep in mind all Sub-Moa barrels to-date in Scout rifles we provided as blanks. This means the gun builder is responsible for crowning, chambering, internal and external finishing.
It is unfortunate this barrel has made it to the end-user; it is not indicative of Sub-Moa's commitment to producing the best airgun barrels on the planet.
Do you feel the price of these barrels is worth the cost compared to OEM barrel that comes with the EDgun Leshiy? Did you do a comparison barrel against barrel?Some 50 yd groups out of my leishy 2 .30 with a submoa barrel!

It's a 1/4 NPT thread. Very common in the U.S. for any gauge 2" diameter or larger.What is the thread specification of the pressure gauge?
just got a reply... AOA is their distributor in the USA and AOA does not carry the tube version... they have 3 in .177 and 2 in .22 left in stockEmail them, I ordered all my Redwolf parts that way. I assume you can but regulations might be an issue.
