Im new to the world of AR's although I've done a lot of reading up on on the subject as I get close to purchasing one or potentially building one. But as I read through this forum I am yet to find anyone talking about an AR in .308. Are they that uncommon? I use a .308 for hunting and have the rounds and the ability to reload them so thats kind of why I was considering it. Thanks. Wanna kill these ads? We can help!
