I printed the ARK by AWCY, but had a 4.5" barrel. I could either use a slim flash can that fit under the handguards, or modify the design. I talked to @invaderzip about it, and he modified it for me, to which I modified even more so I could use a normal flash can or suppressor.
This file is like 95% the work of @invaderzip, and 5% mine, but I didn't see it get posted anywhere and wanted to share in case someone else wanted it.
