I went and bought a Celcius CTW about a month or so ago and finally got too use it in a game. I'm a bit disappointed with it too be honest. For some reason it's chopping up bb's along with double feeding about every ten rounds. I can't figure out as too why. I'm currently using KSC .25 gram bb's and for magazines i'm using systema PTW ones. Just seems to me the magazines can't feed it quick enought which doesn't make any sense since my Systema PTW has never jammed or chopped one bb and i've had it for a year. I've checked the cylinder to make sure it's all the way in i'm honestly not sure what the issue is, just seems like the rate of fire might be a bit too high.

Yes it's one of the newer models and yes I bought it from hot spot.

My CTW feeds just fine with the KSC og G&P bb`s (both 0.25g)in the original magazine and my Vanaras magazines. Is it long since you lubed your mag? I had a couple of misfeeds and chops with my Vanaras mags until i lubed them.. since then i have had no misfeeds or chops.

It's been a bit since I've lubed them up but I use the exact same ones in my systema without any issues, even the celcius magazine that came with the gun is having the chopping issue and it seems to only happen on auto I'm only doing maybe 5 -7 round burst. So I was thinking the cylinder maybe too weak for the battery.

hm...thats weird, i have the cs350 cylinder and i run a 11.1volt 2400mah lipo... so my ROF is 22.9rps when i chronoed it. I haven`t gotten any chops.. have you tried a different bb brand? the CTW is really really picky when it comes to bb`s.

Thats what I was afraid of when I bought it. I've only used the KSC .25 gram bb's in it since thats all I have at the moment. I figured they were one of the top bb's for quality. I was thinking about Javlin bb's next i've heard some good things about them.

Just not understanding why i'm having such an issue with chopping since no one else has, because i've search online too see if anyone else is having this issue.

Try this. Can't guarntee it will work but it may. In the buffer tube that screw to get to the inside, there should be o rings or spacers. Remove one. This will set the cylinder back a bit. Which may help with the chopping. Also lube both the mags and hop up and barrell. The systema mags don't work as well on full auto with the celcius. (Not as high speed) I've heard people with older model celcius' did this to fix chopping. I hope this works for you. Let us all know.

Well, that worked for about two magazines then it started to chop again...time to send it to hot spot.

Did you try to lube the mags?

Yes I did

Weird.. and KSC is one of the best bb`s for the CTW too... hm..this one got me puzzled.

I have noticed that each gun seems to like different ammo. I use G&G bios and they work fine. No problems. Others on my team use different brands. No one brand seems to work in all of four CTW's. It looks like trial and error.

I had this issue the problem was that the cylinder spring screw came loose. Take your cylinder out shake it if you hear something moving in the cylinder it that screw.

I completly forgot about that one. If that is it don't forget to lock tight the screw so it doesn't happen again

hey try using madbull or g&g bbs some people i play with use diff bbs cuz they dont work in my gun and mine wont work in theirs. I use g&g, and some use the ksc because the g&gs wont work and then one uses g&g bios cuz mine and the ksc wont work but i cant use the bios

Well, I sent it out to Hot Spot airsoft today along with a bag of the KSC that I use. Hopefully they can figure out the issue.

Thank you all for helping out.
