The bushmaster - an AR15 derivative - is very commonly used in both sport shooting; and properly scoped for hunting as well. They are much easier to care for than traditional looking hunting rifles. If you've ever owned one you'd know how much cleaning and care it takes to keep the traditional wood stocks clean and nick/damage free. The bushmaster with polycarbonate shell is much more durable and much easier and cheaply services or replaced.
The bushmaster comes in several calibers and is functionally no different than most hunting rifles.
It's no more an assault rifle than any of my Brownings. It takes its rugged design structure from well known assault rifles, but beyond its appearance it shares no other qualities. It is much more a hunting/sporting rifle than as assault rifle.
After you ban a bunch of guns for their looks; The next time somebody uses a Browning rifle instead will you call it an assault rifle too?
Stop funding needle exchange programs; abortions on demand and other pet programs and reopen mental health facilities and get these loose time bombs off our streets. It isn't the guns; it's the people and a lack of respect for life.
