Yes, the BG10 is compatible with the 80 Percent Arms AR-10 DPMS Gen 1 pattern lower!
The BG10 comes with five adjustable shims specifically to accommodate the varying magwell dimensions found across different AR-10 lower receivers, including the 80 Percent Arms DPMS Gen 1 pattern. The shims ensure a secure, snug fit so your brass catcher stays in place and functions properly
