I'm in the market for my first long gun. I have a dept issued 12 gauge and need to supplement that with a rifle. I want to go with a .308 due to ammo availability and increased power over the .223. Have thought about an AR-10 by H&K and DS Arms as well as the M1A. I will not be purchasing until the fall but wanted to get some expert advice on what direction to go. I don't buy many guns so I can afford to spend decent money on the few that I purchase, still have to justify the expense to my wife though. Thanks for the help.
