The AR15 or AR10/LR308 lower receiver houses the fire control group and attaches the buffer/stock assembly, the grip and the upper assembly.  There are no compatibility issues between AR15 lower receivers and AR15 upper receivers - any AR15 lower will assemble to any AR15 upper.  The AR10/LR308 platform is less standardized so the AR10/LR308 lower receiver pattern must match the upper receiver.  The two most popular AR10/LR308 patterns are DPMS (LR308) and Aero Precision M5 (AR10). When you purchase an AR15 or AR10/LR308 lower receiver, will initiate an FFL Transfer to a FFL Dealer you specify at checkout.  If you have any questions about upper receiver / lower receiver compatibility or the FFL Transfer process, call our friendly customer service team.   888.706.0633 stocks AR15 and AR10/LR308 lower receivers from top US manufacturers including Aero Precision, Anderson Manufacturing, ZRO Delta, and others.
