    .22 LCS SK-19 barrel removal for cleaning and/or polishing. The barrel is a pretty thick stainless steel LW Poly barrel. 

    Remove air bottle by unscrewing like an FX Crown or Impact. No need to depressurize. Then unscrew shroud by turning the moderator. It will pull right off.  Pull off shroud if it doesn’t come off with the moderator. 

    Match mark the receiver and barrel so you know where it goes when you reassemble. Next loosen the two 4mm screws in the right side of the gun below the barrel on the side. 

    Finally unscrew the barrel and slide it out. Reverse the procedure to reassemble. Easy. 
    Make sure you line up your march marks as described above exactly. The barrel will screw in until it stops and go past the mark just a little. Unscrew a hair until the marks align. 
     


    Good as new.

    I wonder who could have motivated them to make a video 😃

    That's good.  They took my little talk with them yesterday and put it into action.  My gun is awaiting pickup by UPS.  In my case, the gun arrived brand new in a non-functional state.  I did not try to change or clean the barrel.  Chris J told me to "unscrew" the barrel a little.  Daren processed the return.  I called to add to the RMA info that the gun was blowing air out the side-only then did TJ tell me that unscrewing it more than the width of a pen line on painters tape could be too much.  Lastly I called Chris J back to express my displeasure with no info on such a necessary basic gun function and I intended to share that info here and other airgun forums.  My last call was 1-16-20 to Chris J.  There was no video then. Today,1-17-20 a video-you're welcomed.

    The flaw in the "mark the barrel" method is, it assumes you have a properly functioning gun from the vendor manufacturer, so you can mark the barrel BEFORE unscrewing it, which was not so in my case.  Oh, and did I mention, there WAS NO VIDEO at the time?  Would have been nice if they emailed me to to tell me about it.

    It's great they made a video.  I did this a month or so ago thought it was good enough.  But yours is a bit better.

    Wow, I can see that this company really pissed you off and should never sell another gun. I have one and am quite happy with it. I'm hoping that you can return this gun and find something that works for you. Any purchase can take a turn for the worse. If the dealer or the manufacturer does not address the issue, that's a problem. If they try to help, take their advice and go from there. I try to work things out, and not attempt to trash a brand or company. But, that's just me.

    I did not trash any brand or company.  Just wanted others to be aware of some of these issues before they lay down their hard earned cash.  I wish others who had these guns before me would have shared info so I could have at least been aware of what I was getting into.

    Please re-read MY post and tell me where I trashed a brand or company.  Obviously, a reading comprehension problem:

    @cmatera,

    I honestly don’t think you’re being fair. The above statement implies that everyone that bought one before you had problems. I shot a .25 for two days in November. And then bought a .22 a couple weeks ago. Both performed flawlessly and were as accurate as any Impact or Crown out to 100 yards. I also shot one at RMAC in June last year and it worked fine. So to imply that they all are flawed is just shortsighted and unfair.

    You have a sample point of a one gun. No disrespect intended. How about you let us know how it turns out with yours? Are you getting it fixed or returning it for a refund?  It appears the dealer is taking care of you?  Looking forward to finding out how your story goes…

    Again reading comprehension.  I did say in my post I would let others know how it worked out.  Although it came out by inference through the release of the video, I never even mentioned the name of the dealer.  Please show where I did..  I am not being unfair or blaming others who got their guns before me who did not have problems so could not report them. I was just responding to another non-reader who accused me of "trashing" a brand or company.  Obviously, this forum, like most, have their industry hacks who jump up to justify things anytime someone tries to relate their experience with a product to help other average users.

    The gun is going back on their dime for repair.  They have been fair.  To repeat, (also in my post) we shall see.

    So you are saying , the transfer port gets blocked if it is in or out too far and not lined up?

    Well this is the same with all pcp air guns isnt it? if you put a barrel in a fx or cricket  where the transfer port hole is in the barrel  and dont line things up you can get a leak or loss of power , or even block it off  ,lol

    I guess This is why I like to learn all my guns..So Cmatera are you getting it back ? I am sure we all got guns with something loose or leaking it happens , I like  Manufactures who accurately post diagrams and sizes t seals and things.

     

    As for Cleaning barrel thanks Centercut , I almost bought one but I asked how do you clean and was told use a pellet cleaning pellet , or remove barrel.I now see it isnt a big deal to remove it , and looks built very robust nice thick barrel.

    I also like barrels threaded like this and Taipan ,

    Great  LOU

    Funny how 2 posters knew about a video 5 minutes after it was posted.  Shameless industry hacks.

    How about using an old school spark plug gap Gage and measure the gap between the barrel and the rotary magazine before removing and then use that gage to set the proper gap when screwing the barrel back in.

    No way to get one in.  Access is blocked.  I said in my original post it would be great if the manufacturer put a slot in the right place so you could do that and get it exact every time.  I also said it would be great if the threaded shroud/baffle nut was a hex so you could use a torque wrench to set it properly if a spec was provided.  Someone replied that the threaded part does not do anything, it just holds the shroud on.  I'm pretty sure they are wrong.  In the AoA review by Jared, he said the barrel is tensioned and something to the effect to leave it alone.  Of course that is not possible if you follow their later instructions in today's video on cleaning or changing the barrel.  From my original post:

    Let me tell you the story of my LCS SK-19.  It arrived last Friday 1-10-20 at about 6 PM.  It was already dark.  On Saturday 1-11-20, I scoped the gun and went to sight it in.  First magazine of 19 rounds I had 2 failure to fires, air yes pellet no.  Second magazine of 19 rounds, three rounds air yes, pellet no.  3rd mag only shot 5, two more air but no pellet.  I did not clean this gun or touch it in any way-just pellets (JSB 33.95gr) and air.  That's why I never touch a new gun, then vendors say you caused the problem.

    Monday1-13, I call the vendor (who has been excellent).  They tell me the barrel may be screwed in too far and not allowing the fixed non-removeable magazine to rotate, and to try unscrewing the barrel.  Fired 2 mags of 19, thought problem was solved (even called vendor and waited 20 minutes on hold to tell them).  Wednesday 1-15-20.  Two skunks in my yard (the reason I bought the gun).  Shot the first, went to shoot the second no pellet.  I lifted the mag levers on both sides of the gun, rotated the mag clockwise one position by hand, re-closed the levers and shot and killed the second, as it was still there.  When I checked the mag, there were two pellets missing, even though I fired 3 times.

    I called the vendor today 1-16-20 and am sending the gun back.  In getting it ready to ship I wanted to unload the magazine.  Since it's fixed and non-removable how can I?  Simple shoot it.  Prior to this time I had been shooting the gun off a gun rest, and with the long ATN 4K Pro scope I was behind the gun.  While emptying the pellets by shooting into the ground (scope was taken off), I felt air puffing on my right cheek.  I called the vendor to add this info to the RMA.  They said the barrel was probably unscrewed too far, causing the air to blow out the side.

    Here's what I would like my fellow air gunners to know.  First, the only way to clean this gun due to the fixed magazine is to remove the barrel. Second, the barrel is tensioned in the front by the moderator baffle nut.  Third, once you remove the barrel to clean it, It will be very difficult if not impossible, to get the barrel in the proper position.  Too far back, magazine will not work.  Too far forward, air comes out the side.  There are NO specs on the baffle nut to know how to properly tension the barrel.  I told the vendor I put a piece of painters tape at 12 o'clock on the barrel before I loosened it.  He said "if you make a pen mark on the tape at 12 o'clock, turning the barrel more than the width of the pen mark, it could be too much".  You will have these issues EVERY TIME you remove the barrel for cleaning.  Not a very good design, not very good QC.  There should have been a slot in the side to insert a feelers gauge to get the spacing correct and there should have been a spec on the barrel tension, and a way (hint-a hex for a torque wrench) to apply it. 

    I should have bought an Impact MKII.

    Anyone who says I trashed a manufacturer or attacked others for not reporting the problem either cannot read or is lying.

    Watch the video and listen to what Jared says at 6:15:

    Has nothing to do with the transfer port. If the breech end of the barrel touches up against the fixed revolving magazine, the magazine wont rotate when the gun is fired. There needs to be a little space between the barrel and magazine, just like a revolver powder burner.
