Exactly my reason for doing it.
I remember taking the Air Speed (?) apart and the foam buffer was grey with dust.

So air wave does move back... I guess the final question is how effective.... Thinking of the RTI Mora, it has a beast of a shroud.

There is also a muzzle brake that treads on the barrel with an o'ring to center the shroud. It has huge holes in it. I don't think that it's needed on this gun either. Might just cover it with tape & see if that does anything? I want all my lead dust going forward.

The shroud and 9 baffles inside work well for the size.
After the shroud holes are covered it gets even more quiet.
With an additional moderator it's really quiet.

Hello!
Adding a weep hole towards the furthest part of the barrel shroud is not necessary to allow sound to escape as it is to enable gas pressure to escape. When the shroud is sealed on both ends, air fills the cavity and is forced to compress because of the limited free area in the shroud cavity. Once the shroud cavity reaches an equalized pressure, it rejects any additional air. Because the shroud cavity will not allow any additional air in, the air will find the point of least resistance to escape, which typically is back into the projectile's air stream. If you allow the air to travel and displace at the furthest point, you have a controlled release, thus increasing the amount of air that can flow through the barrel shroud.
The Mr Clean Magic Easer (Melamine foam) is simply a diffuser to slightly restrict airflow and to act as a filter medium to grab any lead particles in the air stream.
Shoot safe!

Caution Pinty Flashpup owners... I noticed yesterday afternoon after shooting my Flashpup that the collar that the shroud screws into had moved up the barrel about a half inch and the grub screw that holds it had scored the barrel a bit as it moved up. I assume that happened because the grub screw had loosened up? Once I had the shroud off there were no signs of pellet clipping on any of the baffles, so I reassembled everything and will be watching to see if the grub screw gets loose again. (May need some Blue Loctite...) Might want to check your grub screw tighness!!
With the shroud off I noticed that the barrrel is threaded, but don't think it is 1/2-20?

Your right about it screwing right on, but it's not 1/2x20 threads. I have 3 China pups. A P-15, Bull shark & a Pinty. The 1/2 x 20 mod will screw on loosely & tighten up, but it's not a guarantee it will not clip your pellets. I have tried weihrauch mods on all 3 of my pups barrels & they worked fine, but there is no guarantee the next one won't clip?

No, I don't have a tread pitch gauge but I'm sure it's a metric size. Close but not exact. I was shooting my Pup a few days ago & I heard the dreaded hiss sound coming out of the action/barrel & gun would not accept any air when I tried to refill. Pulled the valve & poppet thinking one or the other was bad? Everything looked good. Wrote Pinty & they offered $35.00 to have it fixed locally? I don't know of any smith that works that cheap! I watched a video from Haji that showed dry burnishing the valve/poppet & after I did that it aired up and is holding air fine now.

Hi Everyone, so i purchased the pinty bullpup and the pinty aforce. The aforce shoots perfect but the bullpup shoots all over the place. I cleaned the barrel and played around with the hammer adjustment with no luck. The only pellets did decent were the 15 grain JSB, Apolo 16 grain and JTS 18 grain. Does anyone have any recommendations?

Turk73=You cleaned the barrel, so that's good. Check that all your screws are tight also. There is a screw under the picatinny mount that tightens the barrel. If you can,I would remove the shroud & baffles and shoot it to tell if your pellets are clipping? Also get a chrony because just turning the hammer spring in or out will not tell you what the gun is doing. Pinty has been good about answering emails about problems & will exchange your rifle if you can't get it to shoot.

According to the nice folks at Pinty, wait until October then. Also, they are bringing in a .175 cal air rifle! Nope, not a misprint. An all new something or other abomination in .175 caliber. Only problems being, #1. Pinty can't repair any of the 3 rifles they have out now. They try to get customers to repair new non working guns themselves. #2. Pinty doesn't even carry spare magazines for the P-Pup or the P-Rifle, good thing the P-rifle mag is a common type, and the P-Pup mag is readily made by several good folks with printers. And last but not least, Who makes .175 pellets? The Chinese? No one here in the U.S. sells .175 pellets. Are folks supposed to buy them up, and rely only on Pinty for pellets? Yeah, good luck with that caliber. I see a lot of those being pawned off for little of nothing, Pinty stopping importation, and all pellets for it drying up.

Saying all this though, I love my P-Pup. It is extremely accurate, shoots 14.3 cphp's at near 880fps for first several magazines, and knocks the tree rats right outta my oak and pecan trees.

Last thing I need/want is yet another caliber to buy ammo for. The ideal situation for me would be to reduce my entire collection to the .22 and .25 guns that shoot my cast pellets good. If it weren't for the packing and cost/hassle of shipping I'd be doing just that now. We live in a very rural area so selling them locally is a slim option.
