The Gibbz Arms receiver is 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. Tactical Kinetics is one of our major partners and they produce high quality, accurate barrels. The Axis Rail is a free floated system, M-LOK slots on all three sides, full length picatinny rail at the top, lightweight handguard. Barrel Nut is made out of solid steel to ensure a solid mounting system.
Comes with a LEFT HAND Nitride Bolt Carrier Group. Also included is a lower parts kit and M4 stock kit - everything needed to turn your stripped lower receiver into a full rifle.
We can also UPGRADE the GAS BLOCK to an Adjustable Gas Block. Great option if you are using a suppressor or just want to fine tune your system.
SOPMOD stock by JE Machine Tech is OPTIONAL . Features a wide cheek weld, rubber non slip butt pad, two water tight storage compartments and stainless steel QD swivel mount. Made in the US.
We also offer a CHOICE of Muzzle Devices - upgrade the flash hider to a Black or Stainless Competition Muzzle Brake. This is an enhanced version of the popular style muzzle brakes. The baffles and ports are milled larger to drive pressure up and to keep the muzzle down more effectively.
We can also UPGRADE the TRIGGER to a Rise Armament RAVE 140 or a Timney Impact Trigger. Great option if you are looking for a lighter and more crisp trigger pull.
We also offer an OPTION to add a 80% 7075 T6 Aluminum Milspec Lower Receiver (Raw or Anodized) to your kit.
