Product Details
This is your lower receiver workhorse - it's the part that legally defines your rifle and handles all the mechanical action, and this one's built tough by Primary Weapons Systems with a matte black finish that won't show fingerprints or wear. The MK2 is set up to work with multiple calibers, so if you decide to build out different uppers down the road, you've got the foundation to do it. If you're new to building or just want a solid, reliable base, this gets the job done without any fuss.
