Hey guys, got my buddies rifle and having issues with BBs jamming
this is 2nd jam and it's a mother bitch to clear... I'm thinking either;
1 the mag is feeding too fast
2 the bolt is too slow
3 it doesn't like these ics bbs..
4 i'm a noob and forgetting something straight forward

If you need more info, please say so

ps: going to sleep shortly so sorry if i don't respond quickly
pss: i forgot...how do you remove the hop-up/barrel? this jam would be easier to clean if i could take that bitch out
I assume it's the weird looking ring with 4 indentations at base of barrel but i have no idea how i would find a tool that loosen that :(

ahem

I find the bolt isn't pushing the bb into the chamber and thus not firing it then the next bb comes uo and geta pushed down cause one ib chamber already... I have a feeling i just have to do some good lubing...

Shooting fine now with madbull BBs :)
