I am somewhat new to the AR-15 world, however I am looking to get my first AR. The Carbon 15 is on sale everywhere the day after thanksgiving sale, ie Cabela's, Gander Mtn., for $600. Is that really a deal? And would it be a good rifle for patrol/3 gun comp? As my first one I want a decent rifle but one I can also try putting new parts on/customizing to make something that fits what I'm looking for. Thanks Wanna kill these ads? We can help!
