What did you do airgun related today.

Heck man that's office furniture quality.. pen set over here , stapler over there a few folders strowed around and a leverno crt computer monitor smack dab in the middle.. ..😜
LOL... Wife said it looks like a drafting table.
I suppose it could be whatever ya wanted it to be.

Benjamin  Post antique discos and how yours is tuned.

177 with 2 lengths of pull from previous owner. Arken 4-16 44 ffp 900 fps with cphp almost as precise as my fx guns, 25 extremely close shots per fill (2100g1500). 0.042 hammer spring, mrod trigger that borders on too light. Aoa hdd. Stock is about to get a refinish.

Pretty disco in 22, vortex viper pst 2.5-10 x44 sfp(good scope but I hate second focal plane) 700-791 fps with either cphp, hades or jsb 15 grain. 45 shots on a fill(1800 down to 1100). Stock 177 disco spring. Stock trigger. Will get an aoa hdd.

I'm going to start messing with hammer mass, travel, spring rates and spring lengths. Might make a tail cap with power adjuster that allows you to remove the springs without disassembly of the gun.

Went from fx to discos in reverse. They're just a simply joy and punch way above their weight for the price.

The top one I'm going to attempt something crazy. Spraying camo with wood dye stain and an air brush and blending. Since I do dye stain all the time at work. If it sucks I sand it down and do dark walnut. You'll see the wood thru the camo still. Either that or I'm going to laminate a stock out of exotic hardwoods and machine it all and inlet it. Pic was taken in my woodshop 😁

Umarex  Notos leaking through the barrel.

All I could get out of them was send the gun in. There smith would determine what was wrong with it. Also they won't sell parts. One of their techs last week said it was a three year warranty. I was suspicious of that comment. I thought it was for a year only. I talked to them again this morning. The story changed somewhat. The three year warranty is only good if their smith determines it's a safety issue. The tech I talked to...couldn't tell me what that was...soooo he said "send it in".

I tried cocking the rifle...it doesn't leak through the barrel anymore...now it's leaking right at where the air tube screws into the block on the action. Don't know if that is the regulator or maybe the poppet value?? I've taken both apart, and both look okay (whatever that means...lol!). Back to the drawing board!
I don't own a pcp umarex, just a cheesy break barrel pistol. I'd just find a oring kit or list and rebuild the entire gun, it's not that scary. I do fx guns in about 30 minutes, all 7k orings.

The Real Science of Airgun Suppressor Selection

Hey there airheads!

The other day we sent out an email talking about all the years of experience we’ve had working with airgunners around the world—chasing down the best sound suppression possible in the airgun game. We got some great responses back, and thought, why not bring the conversation here to Airgun Nation and keep it going?

One of the big topics that came up was how air volume and internal design, whether it’s a monocore or traditional baffle stack, actually affect the shot report. Sure, there are computer models that can predict airflow and potential decibel reduction, but the reality is airguns behave very differently than firearms. They have their own quirks in how large volumes of air get expelled and how we tame that sound. Even though DonnyFL and airgun suppressors in general have been around for a while now, the science of airgun silence is still very much evolving.

When Donny first started this company, it was a lot of good old-fashioned trial and error. Just the other day, Yolanda was reminiscing about those early days, how she and Donny would stand out in the field doing A/B tests, swapping moderators back and forth, and listening closely to the differences in tone and volume. No meters. No fancy charts. Just honest, real-world feedback about what our ears told us worked best.

Over time, we’ve added sound meters and other R&D tools to the process, but we’ve learned something important: feedback from real shooters still matters more than any number on a screen. A meter might tell you it’s “quieter,” but your ears can reveal something completely different, especially downrange.

So how do you choose the right suppressor? It’s not as simple as picking the “quietest” one on the list. Caliber and power tuning matter, a hot-rodded .22 PCP can be just as loud, or louder, than a .22LR rimfire. Barrel system design plays a role too. Shorter barrels often have a sharper, louder report, while longer barrels can be sensitive to weight on the muzzle and may not play nicely with a heavy suppressor.

Then there’s how you actually use your rifle. In competition, suppression might not be the top priority, you might be more focused on how a suppressor can influence barrel harmonics. On the other hand, if you’re pesting in your backyard or working in a sound-sensitive area, maximum suppression becomes a must-have.

The quick and dirty rule is that more internal volume usually means better airgun suppression. But that’s oversimplifying it. Tone matters just as much, and in some cases, going with a really long moderator may hurt the balance or handling of your rifle.
We’re working on a comprehensive air rifle suppressor selection guide to help make those decisions easier. In the meantime, we want to hear from you. The best part about the DonnyFL community has always been the feedback we get from real shooters. We started out as a grassroots company right here in the online forums, and that community-first approach will always be part of who we are.

So, how do you judge airgun suppressor effectiveness? Is it tone, volume, group size, or a mix of everything? Got a favorite testing method you trust? Let’s make this thread a go-to resource for anyone looking to get the most out of their airgun sound suppression. Also, check out our full lineup of airgun moderators and air rifle suppressors!

Umarex  Notos leaking through the barrel.

Thanks to everyone.

I can now take this Notos apart and put it back to gather just about blindfolded...lol!

I did order a poppet valve from Mable and got a couple of sets of barrel o-rings coming. Pretty cheap stuff in the "scheme of things". I pulled the air tube apart again and adjusted the regulator back and worth (lubed o-rings again) and pressured it up. It held 2800psi pressure for about an hour "until" I dry fired it. Air went out of the muzzle end of the barrel again.

I'm gonna wait until the poppet valve and the barrel o-rings get here before trying anything else. I may be into one of the Huben Power Dream Regulators. I was hoping not for a couple of reasons...namely I didn't want to spend the cost of that regulator and a bottle for it (might as well buy a new Notos), and I do like the factory tube and number of shots for what I do with the Notos. I have a FX for the other stuff. I've had it seven years and shot thousands of Sage Rats with it and no problems to date.

Thanks again.
Thats a legitimate poppet issue. Or valve housing oring

Can anyone tell me the best way to sell a PCP Airgun

I'm in Atlanta. We just bought a new house and I don't have access to as much outdoor space as I used to. Originally I bought my pcp to handle a squirrel issue that I had in my attic. Let me tell ya, my daystate was more than capable. What other youtubers do you watch for airgunning?
100 percent Peppermint oil on cotton balls will keep mice and Squirrels out . pure peppermint oil NOT the stuff in the food / baking isle just Google it .

Pure Lead: The Unspoken Advantage in Airgun Slugs

NSA Sold? When & to whom?
yes I am curious as well..I bought a box of 22@217 of H&N 40 grain slugs and same thing with Zan.. back in October.. I shot a lot of them in my Condor's..Condor and Condor SS and I really couldn't tell any difference between them but the H & N I think was slightly better.. I think Zan is package a bit better for shipping but I honestly like the screw on tins.. and slugs get a lot less damage than pellets in shipping.

Umarex  Notos leaking through the barrel.

It appears that even after you replace the oring to stop the leak you will still need to cock the gun before filling it to get it to take a charge. This may not be the case after the initial fill as long as there is enough pressure in the valve to overcome the hammer spring.

Two Avenge-X rifles, five months, and a part-time job I’m paying for...

After doing a ton of research and watching numerous videos I was excited to get a .22 caliber Avenge-X to compare to the other PCPs in the cabinet.

Unfortunately a problem with the regulator made it unadjustable and the rifle could not be tuned down to shoot anything less than 25 grain pellets. I returned it for full refund.

Other  Break Barrel VS. Underlever

Makes perfect sense, and my only side lever (an FWB300) is an incredibly accurate gun. I don't compete, but have noticed that in all piston FT competitions virtually all shooters have TX200s or hw97ks. That is not a coincidence.
R
That makes sense. I think FT involves greater ranges than than what those ten meter guns were designed for and need more power. Ranges in FT run from 10 to 55 yards, that would be stretchng the effective range of my FWB 150 or 300.

Umarex  Notos leaking through the barrel.

If the slow leak is the poppet that can be determined by putting a balloon over the end of the barrel. If the poppet is letting air by it will go out the barrel like before. It was leaking there before so it may be the cause ? If it’s leaking where the air tube goes into the action/block that isn’t the poppet and will just be a simple oring.

Surprised you can't get a schematic from the manufacturer. I mean even AEA sent me one after not getting one from the supplier.
