So after a long debate and careful research about the KMP9 and MP7, I've finally decided to go with the MP7, for the slightly better accuracy, as well as the looks, that's what really attracted me to this choice.

I just ordered the gun off asgi, but even after several weeks of careful research, I still don't have all the needed info I would feel comfortable having.

So now I ask this to all MP7 owners on this forum; what to do, and not to do.

The things I do know is not to lubricate the hopup so much, since the bucking will swell

Don't pull the charging handle too hard (That's an obvious one)

And don't go full auto on 2 magazines back to back, I hear it might freeze some o ring in the internal and crack, but I'm not entirely sure.

The rest is common sense; maintain properly, clean, lubricate, use high grade BBs, and so on.

The reason I do ask this question is because I've never really owned a gbb smg, or rifle in that case, so knowing beforehand would be a great way to go!

And thank in advance for the responses, I really look forward to hearing from the experienced x)

Here's how I've maintained mine.  Not heard of some you mention but I don't torture test my own guns.

1.  Use green gas exclusively.
2.  Clean the barrel with water with a tiny bit of dishwashing detergent in it.
3.  Don't "lube" the hopup at all.
4.  Use a thin layer of bottled silicone oil on the moving parts (the bolt).
5.  Put a single drop of bottled silicone oil on the magazine fill port every couple of months (or 1000 rounds).

Golly, this looks like how I maintain my LM4 and GBB pistols too!

My mp7 is probably the least maintained gun on my wall, and it works every time. I run propane, with a tiny amount of silicone at the beginning of the day to make sure I don't dry out o rings, have no run into a single problem yet accept a bucking swell, which was a lubeing accident and does not really happen like everyone says it does. Other than that I don't think your supposed to close the bolt on your mag follower. Other than that you should be good

It's a simple gun to maintain.  Just don't over-lube it.  Honestly I don't see the need to lube it at all if you use green gas because it requires so little.  Just make sure you clean it and maybe re-apply a TINY bit of silicone with a q tip or something.  A drop of silicone on the fill valve is a good idea too.  Everything else is really just common sense.  Don't drop the mags.  Don't slam them in the magwell too hard.  Don't dry fire it too much.  Oh and if you remove the orange tip be sure to get the glue melted well I've heard and seen people twist the outer barrel trying to get it off.  One thing you can do is take a cigarette lighter and turn the little thing on the top which will make flame super big if it won't come off and just heat the flash hider itself up really hot which will naturally melt the glue.  Just get a wrench on it and you'll be good.  My friend's SR10 flash hider was stuck as hell and we took two lighters to it for just a few seconds and it came right off.

That's great to know its easy to maintain. Also what is absolutely frustrating is a day after I order my mp7, the 2 magazine package deal comes out, for the exact same price.. Terribly frustrating.
