Faxon Firearms ARAK-21 XRS Features The Faxon Firearms ARAK-21 XRS runs a gas piston operating system rather than a direct impingement design keeping carbon fouling out of the action for cleaner more reliable cycling. An adjustable gas system lets the shooter tune the piston stroke to match ammunition pressures or suppressor use reducing felt recoil and extending the service life of internal components. The bufferless system trims overall length without sacrificing reliability which matters on a 12.5 pistol build meant to stay compact and maneuverable. A 3-port muzzle brake mounted to the threaded barrel helps control muzzle rise during rapid strings of fire in 5.56 NATO. The billet ARAK-21 XRS lower pairs with an M4 Quad Rail style handguard giving the shooter a full-length mounting surface for lights optics and vertical grips on all four sides. An ambidextrous charging handle and safety selector let right and left-handed shooters run the gun the same way which is a real advantage when switching shooting positions or hands around barricades. The B5 Systems pistol grip provides a secure ergonomic hold that keeps the trigger hand in a natural position during extended use. With a Picatinny optics footprint drilled and tapped on the receiver and a 30-round magazine included the ARAK-21 XRS pistol is ready to accept a red dot and run straight out of the box.
