Guarder 6.02mm Tightbore Inner Barrel for Tokyo Marui Spec AEG Rifles
(Length: 363mm)

"Great case for the price. Have a JG 614 w/crane stock, red dot scope and Madbull Gemtech quick detach mock suppressor and it fits very nicely. Pockets hold my extra mags with no problem.

"I have a G36E, and it just barely fits with the stock extended. (will not fit with mag loaded into the gun unless it's the SL8 mag). The gun measures 3ft 3in. The problem here is that the gun won't fit in there (with ease) if the stock is folded.
Moral of the Story: If you have a G36E, or another gun that measures longer than 3ft, get the 49" bag.

That's my only gripe, and it's not even that bad for me. Otherwise, I love the thing. Nice pockets for extra mags, radios, ect, ect. Love the padding, it certainly doesn't feel like a cheap guitar case.

"How many mm's are you adding to it? its pretty self explanatory

also you could just buy the sniper bag/case
