i believe that is a milspec weapon. it is chambered for both .223 and 5.56. I do not think bushmaster makes any of their rifles that are NOT milspec. I would agree, though. if you are looking for something that is going to be a work rifle (i.e., use it in your job) or you are a competition shooter, there are better rifles on the market. If looking for a "fun gun" or you are not that serious, its not a bad price. I have two bushmaster .223/5.56 at work: one is about 10 years old and have had zero problems with it and can keep a half dollar size group at 100 yds (irons). the newer ones (3yrs) we have are a little problematic. I think bushmaster's quality has decreased some over the last few years, as have other manufactuers. I believe it is due to the demand. companies are cranking these things out fast to keep up and I think it is hurting the overall quality.
