AR10 18" .308 Win A2 Style Upper Reciever


Unlike the AR15 platform, AR10 style rifles do not follow a common specification. For that reason, in most circumstansis the upper receiver and the lower should be manufactured by the same manufacturer. We use the Palmetto State PA-10 upper and lower receivers in our builds, but any upper or lower can be substituted.
