Funny thing, I had never shot an AR or really any kind of gun for that matter. After buying a Remington 870 my first gun & 1,000 rounds of 00 Buck later I decided I was ready so I purchased a SCAR17 as my second ever weapon and first real battle rifle. A year later................well you know the rest of the story!
I wish that I had gotten a SCAR 17 first, I would have saved a lot of money and had an awesome weapon to boot. The ammo is more expensive but it will get the job done. The SCAR is lighter and has more capability than most AR type rifles.
