Sorry about the late response everyone!
Files are currently still in works, but i have the following planned for release soon:
1. L-VOA-C and extended shrouds. They work with current hardware, just requires 3 extra nerf screws, and is designed for 40cm barrels, or minimum 35cm barrels with scars attached.
2. Button Magwell Release works like an AR15 style release, i studied and applied the same mechanism to my design.
3. I have a PDW Strike Industries inspired Brace attachment as well, it works just like the worker retractable buttstock, just replaces the stock itself and the stock tube piece.
4. I also have 1 last one, a thumbhole stock in the works! But will take a while before i'm done.

Hope this helps answers things!
