Troy Pneuma Ambi Charging Handle Features The Troy Industries Pneuma Charging Handle addresses one of the most persistent complaints with AR-15 platforms gas blowback to the face by routing waste gas through dedicated vent channels on the top and bottom of the stem and directing it out the right side of the rifle rather than back at the shooter. A shaped ridge on top of the handle seals against the upper receiver forcing gas through those channels instead of letting it escape upward into the shooter s eyes. This matters most on rifles that run over-gassed or with a suppressor attached where blowback is typically at its worst. The ambidextrous design puts large texture-gripped latches on both sides so left and right handed shooters alike get the same quick positive control during normal or emergency manipulation. Machined from 7075-T6 aircraft grade aluminum and finished in Type III hard coat anodizing the Pneuma is built to survive hard use without wearing down or corroding. The large latches are sized for use with or without gloves and their textured surface provides a nonslip grip even in wet or muddy conditions. Made entirely in the USA this charging handle carries a limited lifetime warranty against manufacturing defects. For shooters running a 5.56 AR platform who want to cut down on gas exposure while improving ergonomics the Troy Industries Pneuma offers a direct functional upgrade over a standard charging handle.
