A bolt-on ported plenum expansion for the Umarex Notos that provides a massive power increase.
Featuring 25cc's of additional plenum space, this mod shows an increase of 60-100 FPS on a stock Notos with 15.9gr pellets and no other adjustments. It's not just the additional plenum volume that makes the difference, it's also the massively increased port size of 8mm compared to the 3mm port on part #42 of a stock Notos. This plenum also features two M8x1 ports for a pressure gauge or degassing screw on either side. The tank is lowered slightly so that it does not interfere with the original moderator, and that means this plenum does NOT require any modifications to install or use. Any bottle adapter or regulator that fits a stock Notos will also fit this plenum. Also comes with a variety of spare o-rings, including two sets of the oddly sized o-rings for the barrel.
