I found a DPMS Panther AR-15. Here's the description. "New, in the box, DPMS Panther A3 Lite 16 AR-15 rifle with collapsable 6 position stock, Forged 7071-T6 aircraft aluminum receiver with Hard coat anodized per Mil Spec and Teflon and coated black, Oval Glacier Hand Guards, Carbine length, A1 Front Sight Weight 6.5 lbs. Length: Extended: 36 3/8" Collapsed: 32 1/2" Each Rifle comes with 2 - 30 round magazines, sling and cleaning brush." is this a good gun for $750?
