As an Owner of a Bushmaster M4A3 and an AR-180 and a Mini-14 Ranch Rifle, here is my observations. The AR-180 is alot easier to clean, but not as accurate as my Bushmaster. I bought the Bushmaster because I carried an M4 in the Army, and I liked them. The Mini 14 is hopeless in accuracy, but it is a rare one, so I keep it. Hope that helps. The AR180 is worth the money.
