I keep hearing the M&P Sport II and Ruger 556 being called entry level rifles. What does that mean? Do I need to spend a $1000 on it to make it a real rifle? What is the AR15 suppose to do that one of these rifles wont do? I have the M&P Sport II and it does everything I could want an AR to do. It's a light easy to maneuver carbine that will outshoot most military style rifles I own. Just because someone spent $1500 on an AR doesn't mean my Sport II is any less effective at the job they were intended to do. If I wanted a 600 yard sniper rifle I wouldn't start with an AR anyway and I'm not going to strap 5 lbs of gadgets on my 6 1/2 lb rifle either. I think I'll just keep my "entry level" rifle as is and let it do the job it was designed for. Anyone else like their "entry level" rifle the way it came from the factory?
