The most important part of building a rifle is actually getting yourself the best components to work with. Rather than have to look all over the place to find those parts, it sometimes helps to just find a complete upper to work with. This still allows you the freedom to tweak the finish product but gives you a solid foundation to work with. The PWS MK107 Piston 223 Rem / 5.56 NATO 7.75″ Complete Upper Triad is an excellent place to start if you want this foundation.
Featuring a KeyMod rail system and an enhanced bolt carrier group, this upper is made to be used by a real tactical operator. It offers a very short barrel design and measures only 9.95” overall. Despite its small size, it still performs as reliably as any full-sized upper. Nicknamed “Diablo,” it mimics the AK’s overall styling and makes for an interesting change to the traditional rifle upper. This upper is made with all MilSpec components, ensuring that you get a rifle truly ready for combat in the field.
