Mp5 sd6 second day of buying it I striped it and replaced every single part with upgrades.then had to cut the spring as it was firing at 5.56fps.still my fave rifle,never let's me down.since then iv added a front drop down hand grip,strobing flashlight, lazer and a scope.

Thank you to everyone who helped with my upside down issue.new mag sorted the issue.thanks again everyone.

Thanks for all the info guys.iv been busy at the air festival today, so I'll give it ago tomorrow. Thanks again everyone.

Oh sorry.it's a tokyo marui.

Sorry I don't understand vfc.what do you mean?

I have a gbb mp5 and for some reason it now only fires upside down.I have stripped it soo many times but after a couple of shots it goes back to only firing upside down Any suggestions would be gratefully received.
