The Valiant Line replaces the standard milspec upper receiver with our premium Non Reciprocating Side Charging Upper Receiver. We partnered with Gibbz Arms to create the Valiant which gives the user maximum top rail access while making it easier to charge the weapon under duress. The premium Valiant also makes it faster to load or reload the weapon as the user no longer needs to take his/her finger off the trigger and refocus while charging the weapon. When seconds count, you can count on our Valiant Line. This Valiant 458 Socom rifle starts with a Gibbz Arms G4 Non Reciprocating Side Charging Billet Aluminum receiver, mated to a Tactical Kinetics 18 inch 458 Socom, Carbine Length Gas System, Nitride/Melonite treated barrel. Tactical Kinetics is one of our major partners in the industry 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. The Bolt Carrier Group we include is M16 Profile, Properly Staked Gas Key, MP Tested and Nitride Treated. 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. Do you want to Side Fold Your AR? We also offer the OPTION to add the Sylvan Arms Side Folding Adapter to fold your AR in two to make it easier to carry and store your weapon.
