    Grouping two plus inches at 75 yards.  So, I figured the barrel needed cleaned after 600+ shots on the new gun. I really did not want to ram a rod down the barrel and push all of the little chunks of lead into the guns action.  So, I loosened and slid the scope rail off but left my scope on it, so I could get a better purchase on the barrel. It would have been easier if I had just removed the bottle instead.  When removing the moderator and shroud grab the moderator, make sure you grip the metal ring at the bottom to remove the whole moderator and shroud assembly, and turn it counter clockwise.  You should not need any tools.  I loosened the two screws on the barrel bands, circled in yellow. Then I put both hands on the barrel and giving it all that I had it broke loose and I managed to unscrew it and get it off.  After a thorough cleaning with a rod, patches and a bronze brush I put it back together good and tight cuz that is the way it was when I took it apart.  Then I grabbed the magazine to see if it would turn.  Not a chance it was locked up tight.  So I needed to lose the barrel a bit but it was on there now and wouldn't budge.  Luckily I had a toothbrush in my cleaning kit. ;^)  It had the rubber thumb and finger rest.  So I cut them off with a razor knife and wrapped one around the barrel so I could put my Knipex pliers on it without doing damage.  That did the trick.  So what I learned was on re-assembly one needs to snug the barrel up and then back it off 1/8th to 1/4 turn so that the magazine will turn freely before tightening the two Allen head machine screws on the barrel bands.

    The gun shot fine after the barrel cleaning. It didn't leak nor did it have to be re-zeroed and groups @ 954fps with the JSB 18.13s were immediately an inch at 75 yards once again.  At the range there is a large 14 by 18 inch steel turkey out at 150 meters so I put the gun in full auto guessed at the holdover and let loose with a burst all shots hit plink plink plink plink plink put a big grin on my face as well as another that saw/heard it. 😃  Sorry no pics my bad. Hope this helps others out that need to clean their guns.

    So, I took it apart again just for you. I did it the easier way this time and just removed the bottle taking care not to scratch it up on the edges of the flimsy Picatinny rail.  I went ahead and pulled the rail and put a couple dabs of hot glue on the edges, circled in red, to keep it from damaging the bottle when I put it back together.

    Is that the one that's made in the US?

    It's assembled in the U.S. I don't know how much of it is actually made here.  Says he who thought it was made in the U.S.

    Aloha Biohazardman, 

    +1 for the information on removal of the barrel, and about how much pellets you went through before the accuracy fell off. I have about 1 tin through my gun now (.25) but 1 tin can go fast with some of my friends shooting my gun. Maybe when I have to clean my barrel and its removed, I'll try jb bore compound and see if that extends the cleaning intervals.

    Aloha,

    I will probly do the JB Bore Paste thing myself soon enough. From all I have read here and elsewhere on the net it helps with accuracy a bit and lengthens cleaning intervals as well.

    I’ve been wanting to do mine but was hoping someone would share their experience first.

    Thanks!

    Good information Bio I just traded for a SK19 25 he told me he'd put around 300 pellets through it and I've put 50-60 through it then the weather turned cold with snow go figure but it's supposed to warm back up next week so I'll be slinging pellets again.

    Just a thought about light cleaning. Turn  gun upside down to keep Crap out of the TP, load the mag with the cotton swab pellets with the first 2-3 with your cleaner then several dry. Maybe wait a few minute minutes between wet and dry.

    Great info. –  I had read about needing to back it off 1/8th to 1/4 turn so that the magazine will turn freely before tightening the two Allen head machine screws on the barrel bands in another post somewhere. 

    If your not already using a silicone based lube, you might try one to help with that barrel fouling. Just a thought. 

    I have one of these in .25 coming soon. I know I'll use the existing barrel for a while. But I do plan to put a different non-chocked barrel I have here on mine.

    Order this gun in .22!

    I had to sell my .25 Crown because I couldn't afford to shoot it. $16 a day is too much! So I can only imagine a Semi Auto or F/A .25. 

    be smart and order a .22 in this gun! -Nate

    You just need to start making your own pellets or slugs to make it less expensive and to make it so you have less time to shoot.  ;^)  Yup this thing really eats the pellets it's a good thing that you can't get the magazine out otherwise it would get really spendy.  That is the reason I went with the.22.

    The idea of the cleaning swabs/slugs might be tempting, but I'd be worried that they might pile up in the moderator/air stripper.😕

    The moderator is easily removed so it's not a problem if that is the way one wishes to do it.

    I started casting both slugs and pellets for my AG's years ago. Slugs for about 7-10 years now. I reclaim much of the lead in bullet traps. At 3 to 500 a day, I couldn't afford it being disabled. Sure has made a huge difference.

    Learned that once you seriously go slugs, you never go back to pellets. LOL ;<)
