What is the closest rifle to the MK 11 the Marines use. I am looking for a recreation, not an off the shelf .308. I believe Knights Arm makes the MK 11 but from my understanding they dont sell to the public yet. Can I piece one near as possible to the MK 11. I like they SASS but kinda pricey. Any help appreciated as where I am from no one else has any of the black rifles so all my help comes from you guys which is probably better.
