Comes with 3 mags, laylax barrel, autobot bucking, guns modify hop wheel (better adjustment), spring guide and spring upgrade. Mags are silent fill (o rings) and I upgraded the rubber vent valve on top of the mags with guarder ones to get more fps (gained like 10fps though)

Comes with a repro surefire light

Can't remember what else

If you want a holster for it, I have a safariland multicam one never used (repro but a good repro) I can throw in for like 50 (cost like 115 new)
