Please excuse my ignorance in the AR world. That said, I have a DPMS Panther LR .308 with a stainless fluted 24" bull barrel that got handed to me after only a handful of shots since the buyer owes me money he doesn't have. I hoped to sell it but haven't seen more than drool on the chins of those who wanted it but didn't have cash. I've never been an AR fan, preferring bolt actions to get the most accuracy while minimizing cary-weight — now I find there's an AR with bolt-action accuracy & I'm tempted. Since it's not selling I've thought of converting it to .260 and lightening it to make it a more practical deer/coyote rifle. Now my questions: • I understand the conversion to .260 Rem only requires a new barrel. Is that correct? • I lean towards a 24-25" medium contour premium stainless barrel. Is this my best option? • Would I be better off with a lighter barrel, with or without a brake? • How light of a premium barrel can I get away with & still maintain accuracy? • Are there any special barrel features I should spec out for this rifle? • What rifling twist is best for hunting weight .260 Rem bullets? • Who are the best barrel manufacturers for replacement barrels? • Would it be practical to make it into a .243, 260 Rem, .308, switch-barrel gun? • What else can I do to lighten this gun to "cary weight"? • What am I forgetting to ask? Thanks!
