The Sharps Bros. MB47 airsoft rifle is a milled style AK rifle modeled after Bulgarian bodies with the added feature of an integrated M4 buffer extension to easily accommodate common M4 style B-tubes and cheek rests without the need for an adapter. Additionally, the Sharps Bros. MB47 airsoft gun features a well plate that will help eliminate over insertion of the mag in order to quickly and properly index a mag into place. Rounding out these rifle builds to modernize the venerable AK platform are the licensed SLR Rifleworks CNC machined modular M-LOK furniture that runs the entire length of the barrel to provide numerous mounting points for gear and accessories. These furniture are designed to be ultra slim and ergonomic while still remaining lightweight despite running the full length of the barrel. Internally, the rifle features a reinforced 8mm TM compatible gearbox with a quick change locking system; This ensures compatibility with the vast majority of aftermarket parts as well as allowing for easy internal changes without disassembling the gearbox. Rifles come from the factory with neodymium magnet motors for improved out-of-the-box performance.
