FULL AUTOMATIC USAGE
For those who have a registered Drop In Auto Sear (DIAS) or registered full
auto lower and want to make the AOW go full auto, additional parts are required.
They are:
- For DIAS, milling internal sidewalls of lower to fit
- Full auto bolt, that is longer so it will trip the auto sear
- Extension tube so the longer bolt will have a place to travel. The
tube is roughly 3" long and would stick out the end where the normal buffer
would go.

Semi/Full-Auto OA-93 Upper Differences
The below picture shows the semi auto bolt (top) and the full auto bolt
(bottom). The OA-93 full-auto bolt is roughly 2" shorter than a full
length full-auto bolt. For an OA-93 upper to work on a full-auto lower, a
shortened Olympic buffer tube is available from TBP.
