Included with this package: 1 x KA PDW M4 Carbine w/30rd mag: ($399) 1x upgraded RaTech metal nozzle (installed) ($60) (original, backup nozzle is included). 5x 30rd WE M4 open bolt green gas mags ($240) 1x 400rd AW custom drum mag ($149) 1x Red dot sight ($39) 1x forward grip ($13) 3x picatinny side rails ($12) 1x sight protector ($6) 1x KAQDSS NT4 flash hider + AT2000 tracer ($149) Total = $1067 Selling the whole package for $800 (or best offer). A savings of $267! I’ve saved the packaging, so everything comes in it’s original box (except for the magazines) Fielded 3 times, I’ve had it for 8 months. Really just sits on a shelf. None of the mags leak. I’ve run propane through this gun, not just green gas. However, I’ve stripped it and cleaned it after everytime I’ve used it, and have kept it oiled.
