Hello everyone. I was looking into buying a semi-automatic rifle the other day. I want a Bushmaster E2S A1 M4 Type Carbine. It is a .223 with a 30+1 magazine capacity, weighs only about 7 lbs, and is only about 34 inches long overall. The price stands at about $600.00-$700.00 dollars, and seems to be an all around good weapon for defense and target practice. This will be my first gun ever to be purchased in my life, so I want to get some feedback from others before trying to buy it. If anyone also has suggestions on other semi-automatic rifles, let me know please.
