Panther-fluted barrel." It appears to be a DPMS rifle not an Armalite which might give some meaning to the panther line. Tony keeps this weapon when he goes into hiding in The Blue Comet (6.20) and Made in America (6.21). Although Bobby specifically refers to the weapon as an AR-10, he is certainly not a qualified weapons expert.
For the record, neither AR-10s or DPMS rifles have auto selectors. They are civilian rifles and can only be converted to full auto, yet you see the gun has an auto selector switch. So both these guns are ruled out. - Gunmaster45
