AR 15 lower receiver assembly video



Our AR 15 lower receiver assembly video will show you how to assemble your AR 15 from its individual components.

This video features an AR 15 Rifle, however, the same procedures will work with an AR 10 with the exception of the bolt release which is a screw on an AR 10 where it is a roll pin on an AR 15.
