Are you hoping to build your own rifle but looking to get a system you can work with from scratch? Rather than working with a complete upper system, do you want to get the individual components to build a firearm that will really suit your unique needs? When this is what you are looking for, the PWS Modern Musket DI 223 Rem / 5.56 NATO 14.5″ Stripped Upper w/ Pinned FSC (16.8″) may be exactly what you need to start with.
When it comes to quality design, there are few companies that compare with the expertise offered by Primary Weapons Systems. Featuring a 14.5” precision made barrel, this upper comes ready to provide all of the accuracy and stopping power you want from a good battle rifle upper. It uses a machined chrome-molly steel construction with an Isonite QPQ finish to prevent corrosion and increase durability. The barrel is then topped with a permanently pinned FSC muzzle device that reduces felt recoil and diminishes muzzle flash. It uses a 1:8 twist and is chambered for .223 Wylde, which will allow it to take 5.56 NATO or .223 Rem.
It utilizes a free-floating aluminum rail to allow for the most ergonomically sound grip profile and provides for a great starting point for your rifle. Using the KeyMod system, this rail ensures that you are able to quickly and easily attach accessories as needed. This upper is for those who want to build their rifle from the ground up and comes with the PWS enhanced bolt carrier group or the BCM charging handle. The carrier uses a heavier weight to increase dwell time and provide for smoother functioning of the weapon.
If you want to really build your rifle from the ground up, you should definitely consider this stripped upper by PWS.
