Tokyo Marui's SIG SG552 has everything to make it a stand out in stock form. The bottom mounted rail makes adding accessories a snap. Laser, lights, handles and external batteries are just a few of the options you can choose. Add an accessory scope mount and a red dot and you'll be good to go for CQB. The realistic looking standard mag holds fake bullets that give it an aggressive look. The mags also feature an interlocking system that can pair your mags together without a clamp.
