A little more than a year ago, DSA posted this manufacturing video to their YouTube page. While it’s more geared towards marketing and doesn’t cover the topic as thoroughly as I’d like, viewers can still see a few items of interest, such as before-and-after photos of the forgings and castings that end up as finished components in an FAL.
It’s clear DSA has automated the FAL-building process considerably vs. how the rifles were originally intended to be manufactured. With today’s higher value of skilled labor, this is essential to affordable production of firearms components.
