up for sale is a custom blaster I had done for me. it has a Blaster Core 3.1 in it. if you are wondering what a Blaster Core is, its simply the Crystal Focus of blasters. this means it has 5 different blaster sounds and iSaber soundtracks. Heavy Heavy blinkies and Rayprogression. like a saber, it has a 2.1 mm recharge port and will need a 7.4v lith. ion charger.
