I have a great little Mp7 that I love using at the BattleGrounds. The only problem is that it jams. A lot.
I'm sorry, was that your face?!
Use a better quality of bb. Maybe a lil less lube in the mags. Kinda hard to diagnose without a lot more info as to what leads up to the jamming
I have to say try another bb brand. I remember the old maruzen mp5k only run well on toytec or else they jam. also make sure your not over lubing it as it casn gunk up.
Jamming? Or BB's rolling out of the barrel after you shoot and you tip the gun down?
