The Hopup Chamber M4E unit is built w/ an aluminum rotary dial knob for fine hopup adjustments, the precision hopup lever, 4mm bucking nubs to perform best w/ R-Hop, and standard-hop to keep the BB accurate and consistent. It's also designed to accept 21.00mm to 21.25mm nozzle length and fully compatible w/ most aftermarket soft and hard rubber buckings without losing FPS or dropping BBs during use.

Also mounted the removable CNC brass side wings to slide smoothly into the outer-b slots, and included an advanced CNC Delrin locking C-clip to hold the inner-b tightly in place w/o wobbling and twisting.
