Delta rings?! FSB?! What the hells going on?!
Wanted to build something more civilian looking. The gas tube in that FSB is a 7", I'll need a 10" for that barrel and handguard, and the a2 grip and crane are on their way out, but it's on it's way. Some of that's just on there to see what it looks like, you'll see the handguard doesn't have and of it's screws in it at the moment.
The inspiration for this came partly from seeing some of the weapons the Peshmerga and similar forces are using.
