Kinda feel like I'm coming out as a homo here, I've been making fun of these "machine-guns" for years, but I think I might enjoy one of these, in a bigger caliber. I'm told a .308 is called an AR-10, but I have no idea. I just wanna know if it's cheaper to buy one, (are they quality?), or build one (I get pretty particular, don't wanna break the bank.) I do want a bigger caliber, so don't mention a .223/5.56 whatever. I'd like a longer barrel with it, don't know how long they go. Anyway, I hope I didn't hurt any tender feelers here, I just find myself in an odd place here. I'm a hunter, not "tacticool". I've never played MW3, I don't even own an Xbox. So I'm not that guy or anything. Just ignorant.
