Selling a G&G Combat with a Walther Co2 shotgun as the under barrel Was messing around and decided to make a M4 Master Key like in call of duty A sick combo that’s by all definition a CQB monster while doing a great job of holding its own in the outer fields! Rifle fires around 340 fps while the shotgun fires at 350 fps in tri shot and 380fps when switch to single Rifle is AEG and wired to front handguard while Shotgun uses a 19g CO2 tank to shoot (no pumping need!) The rifle and shotgun are attaches together through a picatinny mount which holds them tightly together but are able to be separated so you can get 2 guns or 1 big one! Comes with 2 midcaps mags, M4 Rifle, Sg Walther shotgun, red dot with riser, and tracer unit Open to offers Hit me up with any questions!
