Are you looking to swap out your upper while still using your current bolt carrier group and charging handle? Do you want to upgrade your existing upper build to something that offers improved performance and unrelenting power in the field? If this is what you are searching for, the PWS Modern Musket DI 223 Rem / 5.56 NATO 14.5″ Stripped Upper w/ Pinned Triad (16.7″) may be exactly where you need to look.
The base of this upper is made using a precision forged 14.5” barrel with a 1:8 twist and chambered in .223 Wylde, making it ready to accept both .223 Rem and 5.56 NATO. The barrel is machined using chrome-moly steel and treated with an Isonite QPQ to increase durability and corrosive resistance. It is then topped with a permanently pinned Triad 556 muzzle device which helps to improve accuracy and reduce felt recoil.
It features a free-floating aluminum rail to provide for easy accessory additions and a comfortable grip that employs the KeyMod system for easy accessory attachments. Most importantly, it is made to Military Specifications, ensuring it will be compatible with any standard lower you might wish to use. Made for those who really want to build their own weapon, this comes without the enhanced bolt carrier group or BCM charging handle.
When you want to build a rifle that is really made to last and deal with tactical encounters, this is a great place to start.
