I'm getting my last individually filed tax refund next week, Getting married in June, and I'm looking at using it on a Bushmaster Carbon 15 9mm Carbine. Has anyone had any experiance or could link me to any reviews good or bad? I was able to handle one at a local gun shop and loved the feel and weight. I love my AR, and I've been wanting a Pistol Cartridge carbine, so I figured that this would be the best bang for my buck. Though I did see a HK USC .45ACP. it was about 50 bucks more expensive and the ammo is too Any thoughts or ideas??
