All our upper kits come with everything needed to turn a stripped lower into a complete pistol or rifle. All our uppers are carefully assembled by our team of experienced armorers and tested and ready to go out of the box. Every component is chosen to ensure a high quality upper is produced. Every upper is custom built to order and we go the extra mile to ensure the finished product is to your specifications. We partnered with Gibbz Arms to offer a proprietary patented receiver that has a non reciprocating side charging handle - handle stays forward during cycling. Side handle is on the opposite side of ejection port allowing the shooter to quickly charge or recharge the weapon without taking finger off the trigger and eye off the scope.
