Primary Weapons Systems MK2 MOD 2 Stripped Lower Receiver Features The Primary Weapons Systems MK2 MOD 2 Stripped Lower Receiver is the serialized core of a custom AR platform build machined to accept a wide range of fire control groups and buffer systems so the builder can configure it to their own specification. Finished in a matte black anodized coating the receiver resists wear and corrosion while keeping a consistent factory grade appearance that matches the rest of a PWS build. As a multi caliber receiver it is not limited to a single chambering giving builders flexibility to pair it with an upper in the caliber of their choice. Primary Weapons Systems has built a reputation on precision machined receivers and uppers and this lower continues that standard. Because this is a stripped receiver it arrives without a trigger hammer safety selector pistol grip or buffer tube installed leaving the builder free to select every internal component to match their intended use. This open ended approach suits experienced builders who already have a parts kit or specific components in mind for a precision rifle home defense carbine or competition gun. The semi automatic action is the standard AR pattern so standard AR-15 or AR-10 pattern components will interface with the receiver depending on the caliber configuration chosen. Builders looking for a dependable precision machined foundation for their next AR project will find the Primary Weapons Systems MK2 MOD 2 stripped lower receiver available for sale at GrabAGun.
