***Price Dropped!**** Video of me using it when it was on my Krytac CRB at Tac City Fullerton, CA. https://youtu.be/ZWSvzuif2y0 Selling my Polarstar Jack only (mp5 not included). Works great! Adult owned. COMES WITH LIPO 250mah battery. Was on my Krytac CRB, and currently in my ICS MP5 right now. Never abused. I dont really get to use it much since I use my pistol a lot more. It is only set on semi since the field I play at has restrictions on HPAs. I actually prefer shooting on semi only. I can send videos on how it shoots to make sure that it works. not looking for any trades. need money for new tires for my motorcycle. Just looking for cash. Paypal accepted, but you pay for service fee. PRICE IS SHIPPED. I shared a link to a video of me using it when it was in my Krytac CRB at Tac City Fullerton, CA. If you have any questions, please dont hesitate to ask. thanks for looking!
