Billy's GB Reviews on the SRC Mamba DMR Gel Blaster which he says is a powerful one, showing his personal setup and modifications. External additions include a Bushnell site, a Wolverine hop-up and suppressor unit, an AHG 138 underbarrel shotgun attachment, and a Python foregrip. The blaster uses a large 6,000 mAh 7.4-volt Titan battery housed in the crane stock, accepts standard nylon Gen 8 magazines, and features flip-up iron sights.
