I use the G36 and when using the scope, the stock sticks out a tad too much for me. I'm just around 6ft tall. This should be a good fit for you for outdoor gaming. MP5s and just about any submachine gun style AEG are more for indoor close quarter combat.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
