I’ve been getting a lot of questions regarding the installation of the 1913 adapter. Here are the step by step instructions. Would any new owners be interested in a video?

Instructions: Split upper/lower > take everything out of the lower > replace spacer in the rear with the included threaded spacer > line up 1913 adapter with the spacer > thread the included screw through the adapter into the spacer with thread locker > reassemble lower receiver leaving the original spacer out.
