Barrel/shroud isn’t perpendicular to airtube on R3M .22
Is this normal? I got this gun around Thanksgiving and so far the accuracy is somewhat disappointing, and I noticed the airtube and shroud aren’t spaced the same front to back. Just curious if this is normal or not.

Still on the painkillers hoot ?
I’m confused. I think. I’m not sure.

If I may offer some advice here…from what I gather you had poor groups because your lock nuts came loose due to dirt, causing the hammer spring to malfunction, but cleaning didn’t help. You then noted your “airtube/barrel” was out of balance and leaning upwards! You then managed to “reef” your airtube/barrel into parallel after you loc-tited the hammer spring nut into place, despite some kind of wrench problem? Then the gun started shooting correctly, so you loc-tited everything in place???
Ah…that might have been a mistake! Even though your gun is shooting well at this time, it will eventually come out of “alignment”, in one way or another, and require some sort of adjustment, whether you do it at home, in the shop, or at the beach, it will still present a problem if all parts are solidly bound together with a chemical fixative! There was a fellow here a few years back by the name of “Mamcrackin” who filled his air tube (shroud) with a silicone plug to stop the “pinging” noise from his Talon SS. it was an improper fix because he never could tell if the “ping” ever left on it’s on, or whether the noise went somewhere else, and ceased to be a problem. Later he found that a silicone tube would achieve the same results. He eventually purchased a bi-pod, which didn’t help at all, and ended up leaving the hobby. That was a very sad day for all of us!
We would all hate to see you follow in such a path! Conventional wisdom indicates that it’s best to let your nuts move about freely, without being fixed in place, thus allowing them to react in harmony with the body of the gun, but under spring tension, thus alleviating the perpendicular stress on the shroud/barrel interface, which, as you found out, does sometimes affect alignment and accuracy!
I hope this makes sense, although I’m not certain I said it right. I know what I meant to say, but I’m not certain what I said was what I meant to mean to say! That seems to happen to me a lot.
Perhaps someone else on the forum could state it more clearly…
Kindest regards,

So glad I could clear up your confusion, HOOT!
If you need anything worked on, my schedule is pretty light right now. :rofl:

Sorry Hoot, dealing with two separate issues here. I sort of explained it all in a post above.
Long story short, it grouped poor because it was dirty I think. Then after cleaning it still wasn’t great, but that was because the hammer spring nut came loose and it was losing power.
The airtube/barrel alignment issue was just that the shroud must have been a little crooked, because when I took it all the way off, and then reassembled it, it lined up nicely. I really had to reef on the wrench though, to get it loose. Was worried I’d bend something, it was that tight. Seems OK though.
Seems strange you would have shroud problems, and loc-titing your hammer spring adjuster fixed it. Did you notice anything else being fixed?
How does loc-titing your HST hold your shroud firmly in place? I find that very confusing.
Hoot:
I took the shroud off the other day and when I put it back together the shroud and barrel were even, like they should be. A tiny dab of blue lock tight on the HSA and it stays put. Chronied at 890 avg, with SD of 5 for 60 shots.
This is my guess also…would accout for loss of poop and also the pictured misalignment perhaps…I have made note of Ed himself, dropping this small item in 2 of his videos. Good Luck…let us know.
So this O ring issue could cause the not parallel issue? Is this an easy fix or should I send it back?
When I got this gun just before Thanksgiving, I really didn’t get a chance to shoot much on paper and see how it was grouping. I put a Aeon 6-25×50 on it, did a quick 30 yd sight-in and headed out to the farms to shoot some birds. Last week Monday I had a chance to shoot at the indoor range, (50′), 17 yrds. The groups were quite horrible for an Edgun at that distance. I was kind of shocked. The next day or maybe two days later,I removed the breach block to clean the barrel. It was quite dirty, so I thought maybe that was the accuracy problem. Started shooting from a standing bench setup, out the back window of the mancave, at 30 yards and still had poor performance. In the back of my mind, I kept thinking the gun just didn’t seem as robust as it had been. Then I noticed the spacing issue. There is 5/64 clearance on the end by the scope rail and 14/64 by the muzzle. I have no idea if it was there before the cleaning or not. I suspect it was since I took it back apart and inspected everything really well, and it was still there when I put it back together.
I took the stock off as was suggested and made sure the stock screw wasn’t too tight. This is when I noticed the hammer spring adjuster thingy. The locking nut was loose and it seemed to me like the adjustment screw had backed out some, which is precisely why the gun didn’t feel as robust to me. I played around with a couple different settings, got it back to somewhere close to what it was when I fist got it.(see pic below) I’m going by feel here now as I don’t have a chrony yet, but there is one on my Christmas list. I then shot several more mags through it and the groups were much tighter. The barrel and shroud are still not parallel but at least it’s grouping better.
On a side note, the pressure gauge appeared to stick yesterday. I put 100 shots through it and gauge still said 170 bar.
This is a 30 yard, 10 shot group (1 mag)
Air port O-ring loose or miss size.It abnormal.Happen with my gun.

Some mal-content has deliberately removed/modified the original post, where-in the poster answered his own question.
“…poster”? Indeed, I daresay “impostor” is the correct nomenclature in this instance.
It is as Abraham Lincoln said in 1958….to wit: “You can fool some of the people all of the time, and all of the people some of the time, but one cannot fuck with that which has been previously, and publicly, commented upon, and not have some sharp-witted, and keen-of-eye, citizen fail to cry ‘Havoc!!!’ and arouse the public rabble to incite riot and mayhem, until the disorder has officially, and publicly, been Un-Fucked!”
There you have it…plain and simple. I voted for the man, and his statement has withstood the test of time!!!
“Mad“??? I’ll tell you right now, I’m crazier than a shit-house rat, but that has nothing to do with my eyesight!

That HST is a real PITA. The .25 I have never moves but the .22 moves all the time. It is very sensitive. I recommend a little purple loctite

Nope. Ran out of Tramadol, so I switched to stool softener instead. I didn’t knew you could overdose on stool softeners!!!
Anyway, I realized my mistake, and my head’s starting to clear now. One thing’s for damn certain, you guys can’t call me “Shit for brains” anymore!
