AGT Reg Tester by way of Talon Tunes

I’ve gotten a Talon Tunes reg tester for the Airgun Technology regs. I have many reg testers and this one is as good and even better than any I’ve used.

It delivered quick and was packed well. It comes in a handy tote bag with a draw string. A quality liquid filled Carbo gauge is standard equipment. The machining is great and the anodizing is sugar on top. Quality hardware and o-rings are used throughout. Included is an adapter that enables the user to test the smaller Uragan regulators. Also included is a 4mm bolt to pull the reg from the tester.

First up is the Vulcan reg. Use a quality silicone grease on all o-rings. Use a 3/32 allen to open the bleed fitting. This allows the air to vent as you insert the reg.

The reg is inserted with adjuster facing you

At this point, screw the end cap on until fully seated but just hand tight. Close the 3/32 bleed screw but do not over tighten. Just feel some resistance and stop, not even snug. Attach your reg tester to your pressure source and fill slowly to no more than 300 bar. Via the 3/32 bleed screw, dump a bit of pressure while watching the tester’s gauge and close quickly. Do this a few times. This allows the pressure to settle to the reg’s set point. You now can see where the reg is set and you can test the reg by cycling the pressure with the 3/32 bleed screw. Don’t allow the source pressure to drop too low. You can see below that my Vulcan reg is set to 150 bar.

It’s time to release your source pressure and open the reg’s 3/32 bleed screw to depressurize the tester. Once all gauges confirm zero pressure, remove the hand tightened end to extract the reg. Using the supplies 4mm bolt, thread it into the reg by hand. I found that using my small crescent wrench to aid in pulling the reg worked great as you slide the wrench up to grab the bolt’s head.

Let’s test a Uragan reg. Again use some silicone grease and insert the Uragan reg into the adapter on the opposite side of the adjuster.

Check that your 3/32 bleed screw is open. Insert the reg into the reg tester with the adjuster facing you.

Screw on the end cap, again, fully seated and hand tight. Follow the same direction for pressuring up and testing this Uragan reg as explained above for the Vulcan reg. Confirm that all has been depressurized before extracting the reg.

Remove the adapter from the Uragan reg when done. 

This is a quality reg tester, no doubt. Thumbs up!

A few words on adjusting the reg’s set point; It will behoove you to make a few reference marks on the body of the reg and one on the adjuster. There is a jam nut holding the adjuster position. Loosen this nut to adjust. Counter clockwise increased pressure and clockwise decreases pressure.

Think of the adjuster’s orientation as a minute hand of a clock. In general, moving the adjuster 5 minutes will adjust the pressure by 10 bar. Snug the jam nut before testing reg. 

This sums up my review of this fine product. I hope I’ve helped someone. Later on….

Nice job on a very detailed review with lots of good pictures. Thank you for taking the time to put it together to share with us.

Just a quick comment regarding the advice to lubricate the O-rings with a quality silicone grease, the Superlube #21030 pictured is not a silicone grease and is actually quite flammable. Dielectric grease is a cheap and commonly available source of pure silicone grease.

Thank you. Grabbed the wrong tube. Should have been using this:

Well i would like to, but the thing is i am a bottle filler guy, and getting to the reg of my Vulcan 3 mean i have to dump a lot of air that could be used better.

I do hope someone make a adapter / mod for the V3 so you can take the pressurized bottle off like on my Maverick, and then only have to dump the air that is in the regulated space, even if in both guns that are also a substantial amount, but still a lot less than what is in the bottle too on the V3

I have used super lube for many years on my RC stuff, but then when i needed some grease for a rifle, i could not find the damn stuff, so had to buy oil and grease.

My buddy at least for RC stuff swear to a Mobil marine grease he have been using for decades.
 
That’s a good question. The reason a vent is necessary is because of gas diffusion through the O-rings. The process is normally slow enough that it would not be a concern for a regulator that will be installed briefly into the test fixture. However if one were to leave it pressurized for a few days and then evacuated the air to remove the regulator, it would likely be stuck due to the pressure trapped between the outer O-rings.
 
Exactly... The vent hole functions as a reference pressure (atmospheric) that the regulator is set to and maintains. Typical pressure is about 14.7 psi, so that is your reference and is "felt" by the regulator through the vent hole. All regulators used in airguns need this vent or a way for the regulator to "feel" atmospheric pressure and compare the set pressure to in order to maintain correct set pressure...
 
I forgot to say thanks to Derrick for posting all this. It clears up many of the questions I was going to call Tony about.



Thanks all that commented on the vent hole. I saw how Huma put a slot in their tester, so you can test if the reg is leaking/bleeding out the vent hole. I thought that was pretty slick, and figured I'd ask if this one offers the same.
 
I prefer to have the option of cycling the reg a couple times when testing. 
Like the RAW tester has a push button thay I can tap to simulate a shot. 

this is important because the reg will actually push past the set point as you fill it. Will also settle lower when it refreshes.

Absolutely. That is a function of the 3/32 bleed fitting I speak of on the AGT tester. The tester you are referring to, if it’s the one like I have for the Theoben Rapids and RAWs, has a bleed off that is a spring mounted button. The AGT tester does the same. 
 
I am glad Tony made this tester, definably would like to get one. It almost seems like a must have like a regman for tethering when tuning. It will never take the place of a truly great tuner with great customer service. Derrick is always a joy to work with. Love the Uragan he did for me. AGT makes such great rifles.
