I'm looking for some good ways to clean my MP7, preferably without taking it apart, but I will if I have to. Any suggestions?

You're gong to have to field strip it to do basic maintenance, that's just how it goes. Pop the two pins from the back and pull the back plate off with the stock and the bolt assembly should come right out. If you're using propane you'll notice a lot more grime and residue, but even with green gas you'll see build up, so either way wipe all of the residue off the bolt with a cloth or q-tips, then if you want to you can clean the inside of the receiver as well by sticking q-tips inside or running a cloth inside.

You can also take this opportunity to clean your barrel, which can be done by wrapping a small piece of cloth or napkin through a cleaning rod, then slowly push it down the barrel and pull it back out, be sure NOT to push through the hop up as that may damage the bucking. Also take note that you want to AVOID getting any silicone in your bucking.

When you pull the nozzle forward on the bolt you'll be able to see the o-ring that seals your blow back chamber, so put a drop of silicone oil in there to keep it moist and healthy, DO NOT use spray silicone.

Get a nice thin coating of silicone all over the other moving parts of the bolt and then reassemble the parts inside the receiver. once everything is in the gun put the pins back in, and take note that you MUST NOT let the pins rotate once they go in as they can become stuck and require major maintenance to get them out. Pick a position for them to go through, line them up with the little notches and push all the way through. Cycle the bolt a few times to make sure everything is working right.

I agree with everything except the use of paper, of any kind, to clean the inner barrel.  It can scratch it surface and reduce performance.  Please use only cotton cloth or real gun cleaning patches.  I use 30 cal. patches cut in half.  They are dirt cheap and do a great job.  An old 100% cotton t-shirt will do the job too, just don't cut the patch too big.

Adjustment made, I haven't used newspaper or any kind of rigid paper in the past but I figured it would be better than nothing. Gun cleaning patches would definitely be the best.

I have cleaning patches that I use for cleaning my SR10 :clap: I have one more question though. All I need to remove is the bolt and stock, right?

Basically yes. The stock doesn't need to come off but rather the back plate needs to come off, which the stock is attached through, so keeping the stock connected to the back plate isn't required but it does make it much easier to put everything back together if you use the stock rails as a guide for the bolt and charging handle.
