It would be 11 divided by 25.4 or .44307and more. Be cautious, Sometimes the 11mm may just be close to the real size. Regards, Tom

I didn't bother with the last mag, since he was already off the reg.
Steven, how is your regulator working, are you seeing the same decreasing string as noticed by fuzzygrub on your two rifles?

Yes, initial fill no mods I shot three different pellets. Waited an hour and the velocity dropped a lot. Then refilled to 3600 psi shot again about 4 hours later and velocity seemed stable. Then refilled a third time to 3600 psi. Waited till next day. Velocities went up but not as high as initial fill. Then tested for three more days and the reg stabilized. But I noticed a bit of a drop in velocities at the range today but is was 38 degrees. I just tested two minutes ago after the gun warmed up and the H&N 21 grains shooting back to 890fps which is where I had set them to shoot.Can you take a look at both barrel crowns the second barrel seems to shot more accurately than the first gun? Lothar Walther barrel option?

Your Es is certainly tighter than what I am seeing and Zac has. And it just drifts down ever so slightly, compared to ours. Both of ours are still at factory reg pressure, though. I might try that, even though I was looking to lower it.On a different subject, if you take the shroud off, like to know how yours is compared to air tube. Noticed a big difference in mine, and noticed comments from others. The barrel band is definitely putting tension into the barrel.

Is it about tension or sound?

Once you put the shroud on, it will bend the barrel up.
Yea, looks much better than mine. I can't tell yet if it is a bad bore in the breech or air tube to block to breech alignment. Regardless, doesn't look like there is a way to fix it.

(Viagra will not help) and regulator stability. If it's way out of wack than exchange the gun.

While I've only done one irreversable mod, don't expect ATI to exchange it. I wouldn't want anothers return, either. I'd prefer to buy a replacement breech. That's not possible, either.

Great companies are built on integrity. I understand that these are budget guns but even budget guns need to have a certain level of acceptable performance. Returning substandard performing guns and making the gun manufacturer aware of manufacturing issues givies them a chance to make good on the product. If they were to resell returned known subpar guns I would stop doing business with them. I believe we owe it to the airgun community that spends their hard earned money on these products to make the manufacturer aware of possible issues. If these problem guns are few and far between it will not be costly to the manufacturer. However if this becomes a wide spread problem they need to know or people will just stop buying their guns and they will go out of business not knowing what happened.I'm not trying to be controversial but I really like these guns and do not what them to go away. I feel like we are getting super value and performance. This gun has the chance to tame the outrageous prices of airguns.
