The TROY Pneuma is a gas diffusing ambidextrous charging handle that diverts blowback gasses and eliminates gas to the face. Whether your rifle is over-gassed or suppressed, this charging handle will keep harmful lead and gasses out of your eyes so you can focus on the threat. The Pneuma's vent channels on the top and bottom of the stem divert waste gasses out of the right side of your rifle. A shaped ridge on the top of the charging handle seals your upper receiver and redirects gas through the channels, diffusing it in areas with limited airflow. It's critical for maintaining situational awareness. The Pneuma gives you quick, positive control during normal or emergency weapon manipulation. Made in USA - Like all TROY products, they designed the Pneuma for the harshest fighting conditions on the planet.
