  • DPMS Gen 1 Pattern Compatibility - 
    Because the AR10/AR308 platform was never standardized by the US Military like the AR15 was, there are over a dozen different platforms on the market today. While most components (barrels, triggers, buffer tubes, stocks) are interchangeable, the fit between the upper and lower receivers are not. We utilize the DPMS Gen 1 pattern, as it is the most common and universal of the platforms. Popular brands to match to our lowers are:
    -Aero Precision
    -Thunder Tactical
    -Anyone who lists DPMS Generation 1!
    (We receive many requests about the Palmetto State Armory PA10 platform, and it will NOT work. To our knowledge, the PA10 platform is not compatible with any other brands outside of Palmetto State)
