The TandemKross Advantage Charging Handle and Picatinny Rail for Ruger 10/22 has been given a makeover, to feature a lower to bore axis, reducing the overall height of the optic to the receiver! The precision machined picatinny rail provides Ruger 10/22 owners with a serious "Advantage". In addition to mounting virtually any optic it also features a unique left sided charging handle that actuates but never interferes with the right sided charging handle. This allows shooters, plinkers and competitors alike, to clear jams or charge the gun without ever losing trigger and stock position.
