A brace conversion for the A&K airsoft ACR/Masada stock, along with a pic rail adapter. The brace it uses is essentially a printed strongarm brace from doublestar, though it's not entirely accurate, the model will have to edited if you want the real aluminum brace to fit- primarily it's the bolt holes that are different. I don't have a real doublestar strongarm brace, I merely based it on a diagram they had on their product page, though it didn't include every dimension, but it's pretty much totally accurate besides the bolt hole size/location. Also, the pic rail adapter is purpose built for my JAKL Firebolt V2 buffer tower, you may need to edit it for whatever gun you plan to put this on.

Another note, the brace adapter is kind of tight- especially in the shortest position, you may require some intense fitting or may have to edit the model altogether if your printer is particularily inaccurate.
