LCS air arms SK19 full auto

So I just got done putting the scope on mine and for you all that have them is the barrel shroud moving around a lot? I think they may have missed a set screw.... and I cant seem to get the moderator off so I can get to it..... sad panda. Update no set screw.... so just a rattling barrel shroud...

Mine is the same way. I did get the end cap off of the moderator. It just unscrews and the CF outer tube slides off to expose the inside baffle assembly. Beyond that, I'm stumped. I can't unscrew the baffle assembly. It may be glued or have set screws on it. I think the barrel may have to be removed in order to find out.

Also, my magazine is extremely tight, taking two hands to turn it. It's also not very accurate. These two may be related if I understand the mechanism correctly and as the mag appears to be loosening, the groups are tightening up. I don't think AOA could have loaded the mag and not noticed this.

The inner portion of the moderator is just super tight had to find a flat pry tool to insert in at the base of the baffeling to get leverage. It sits on two washers one the end of the barrel will have to grind one down to get a good fit or i may go into work and make a proper spacer. Not sure if the slop was to allow air to escape or not but if it is they should have just vented the carbon fiber shroud.

Great, I'll try that. Is the barrel thread standard 1/2-20?

Well, I got it off (Thank You BenSeager). I believe I've discovered the accuracy problem: No Rifling! Will be calling AOA tomorrow.

What? No rifling? Nothing at the end either? How could that be missed????????

That's the muzzle end.

Dear lord I havent even shot mine yet.... Gonna check that first lol.

I'd sure like to see a photo of yours (assuming it's rifled and crowned).

Mine looks the same but I just went out and shooting mk2s accuracy looked good so far at 35yds had nickel sized group shooting off a wobbling metal mesh table. Getting a hair under 60ft/lbs at 880ft/sec. Using a bug buster scope I had sitting on a shelf will get an upgrade shortly of one of my Airforce guns.

I don’t own one of this but I do see them pretty much everyday when I stop by AoA. They claim really good accuracy with them and I’m thinking that maybe the rifling is not there because of the full auto capabilities. May e rifling slows the pellet too much to send another few behind it too fast. 

Is it a poly barrel? That's what I'm assuming by the looks of the barrel

Agree-sure looks like there is SOMETHING there.

I don't think so. I pulled a bore mop through the barrel and it had absolutely no tendency to spin as I pulled it out. Probably glare in the photo. Another photo taken directly at the bore looks perfectly round.

Does anyone know how to degas the LCS? I filled mine without a bleed valve. *facepalm*

Just Unscrew the bottle. There will still be a little air left on the other side of the regulator. Just shoot it down after the bottle is removed.



EDIT: I see your problem - No need to shoot down after removing the bottle.

Put a 200 round drum magazine on that baby and I'll buy one. If it's only like 10-12 shots. Not really worth it for full auto

And a remote with two 4500 psi bottles on my back. I could go in the poor-house fast with something that, smiling all the way...

The LCS Barrel is Lothar Walther and it is rifled however the lands are extremely soft. The breech is back bored to allow for proper ingress of pellet into the rifled part of the barrel. Like a funnel.

Do you think this is a Lothar Walther Rifled Barrel? Mine is on the way back to AOA and is scheduled to be delivered on Monday. I hope to hear back shortly thereafter.

Yes the lands are super soft. If you push a pellet through the barrel you will see very small marks on the pellet. That does not mean you do not have an issue.
