Internals are mil spec: chrome lined barrel, m4 feed ramps, bolt MP/ HP tested. Only the butt stock is commercial. This is good to go, nothing to change out of the box. I may change the color of the handguard & butt stock to my favorite FDE, but thats it.
This rifle is made by the original makers of bushmaster & that's mil spec.
