Subs and Adapters
DPI manufactures a large variety of subs and adapters. We manufacture this tooling from heat-treated alloy, which provides maximum strength. All subs and adapters are hardened, making them substantially stronger than the traditional commercially heat-treated bar stock.
Custom breakout profiles are available on any sub or adapter (custom flats or lugs).
