Adjustable Folding Picatinny Arm Brace
Description
This is a folding and telescoping Tailhook style brace to attach to a Picatinny Rail. It is a mashup of the Boolibrace Revision brace, the DDA3V4 brace, and CTRL+Pew Shoulder Thing That Goes Up. The hinge, pin and plug I have not modified. If you have a DDA3V4 lever printed already, you can use that, I didn't do any functional modifications to it. This is a work in progress. Adjustment mechanism does not work, at least not with the spring I have. You may need to sand the arm to get it to fit. Most likely will not get fixed until 2022, but the AWCY? ACR brace/stock package may be released by then, and I might not bother. I think I saved all the STL and 3MF files in millimeter scale, but it's possible I messed up and some are still in inch scale.
