Description

Build your own complete upper utilizing the WarBlock, ready to rock. Starting out the platform is the WarBlock itself expertly aligned and pinned to a Faxon barrel and then mounted to top quality A4 Aero Precision receiver using premium components from Daniel Defense, Rock River Arms, and Del-Ton. Next choose the model of WarBlock; the standard with a built in bayonet lug, or the LiteHunter without it. Moving on to the hand guard selection are the popular and affordable Magpul polymer MOE featuring the M-LOK mounting slots. The standard length MOE M-LOK is shorter and exposes the WarBlock allowing you to retain the use of the built-in QD sling swivel socket, while the SL hand guard extends past and partially shrouds the WarBlock to better protect you from contact burns and helps to make the whole package more streamlined. Following that you have your choice of M16 bolt carrier group including the military standard Parkerized/chrome lined, the harder and more corrosion resistant QPQ nitrided, or pinnacle of anti-friction surface coatings, EXO Fail Zero nickle boron (NiB). No upper is complete without a charging handle and we have several to choose from. The tried and true MIL-STD charging handle, or you can really tip the scales towards excellence with a Bravo Company Gun Fighter Mod4 or A44 ambidextrous charging handle, both in a medium latch size. Not too small to be ineffective, and not too big to be a potential snag hazard. You now have a technically complete upper, but there is one more option that we advocate heavily and that is iron sights. Even with the pervasiveness of red dots and optics, we believe that the actual sights of the weapon are the irons and that no rifle is ever complete without them. Here you have your choice of any combination of the exceptional all steel and Melonited Magpul MBUS Pro irons. Your done, and you now have the essentials all selected and visualized, and now ready to built to order.

*All of our WarBlock uppers contain only the highest quality premium American made name brand components*
