I have a kwa mp7 and every time I shoot it no bbs get shot out, and the bbs stack up in the barrel and they will roll out. Anything I can try to do to fix this?
*EDIT* So I have purchased the reaps hop up and ball bearing and I've put in them both. The results were it was firing but the hop up would cause my bbs to curve up so high after 30ft it was ineffective as a weapon. Yesterday I had taken out the ball bearing and shot it and it worked better, but the range wasn't very good. Is there anything I could do to balance out my hop up to work as its intended. Every where I have read to try and troubleshoot my issue stress the use of the ball bearing.

I'd check your magazine(s) first and see if there is anything wrong with them. After that I'd check the loading nozzle and see if its chipped or something like that. If that doesn't solve the problem then there is probably something wrong with your hop-up.

Sounds like its a problem with the loading nozzle. Because there is no compression reaching the barrel.

It seems like it is the hop up. Thats where the BBs are getting caught in. What should my next step in fixing it be now that I've determined the source of the problem?

I'd say the bucking.

Concur with Hound.
I've heard of situations where the bucking can swell up and prevent consistent firing. Might be time to tear it down and take a look.

Gas guns like to be clean...I'd personally take the time while its apart and clean everything. Than since mp7 suck to take down, upgrade the inner barrel and bucking (hop-up as well if you feel motivated).

The kwa bucking has a tendency to swell up as the material it is made of absorbs silicone lube very easily. You can wash it in soapy water, but to fully cure the problem, just get a REAPS bucking.

Would it be possible to r-hop the mp7?

Anything is possible, but the question is would it be worth the time and probably extra effort? Probably not. You'd most likely have to custom fit and modify the R-Hop into it, because I highly doubt (since AEG and GBB hop-ups are different) that an R-Hop could drop in and then shaped to work like it's originally meant to.

I'm not an expert with R-hops, but I'm pretty sure they are for rifles that don't go through a lot of rounds. Like bolt actions. The MP7 is a submachine gun. I mean its got a 7" barrel. How much can you ask. My bros mp7 is accurate to about 150'. But its made for cqb.
