Description
A drop in auto sear is a small conversion device associated with AR‑15–type rifles that alters the firearm’s firing cycle to enable automatic fire. This device allows for a seamless transition from semi-automatic to fully automatic firing modes, offering increased rate of fire and improved control.
A DIAS doesn’t require a third pin hole, though some receivers will require some milling.
When a DIAS is installed in an AR lower, the hammer is cocked by the bolt carrier as it moves rearward. The carrier pushes the hammer down and the sear of the DIAS grabs the hammer. As it moves forward again, the carrier catches the top of the sear in the DIAS assembly and releases the hammer.
