The only reason I gave it a 4 is that Bushmaster issued a recall right after I bought my rifle. Apparently there is a problem with the trigger mechanism that can wear out and cause the rifle to start slam-firing. They paid for shipping the recall back and took care of everything.
The gun is just smooth as butter. All the controls are around the trigger guard (mag release, bolt release). All ambidextrous. The bolt handle can be swapped to either side and is sooo smooth to rack. Field stripping is also a breeze. A quick twist of the front guard and the barrel separates from the body. Easy to clean and fun to shoot. Uses the regular AR-15 magazines so nothing special. Fun gun I just wish I didn't have to pay 2-grand for the pleasure of shooting it. If you can afford it, you'll love it.
