A retexture that reuses the tan skin of the "AK17" for the rifles you assemble and steal in the Midland Ranch heist. Also changes the blueprint to a proper model (the default one is that of the 2013 prototype instead of the... sigh... "final version") that is twice the resolution of the original blerrie blurry mess. I outlined it myself from reference pictures.
There is also a two-tone version that has a black receiver. Pick one or the other.
