I am wanting to trade or maybe sell a Professional Ordinance (Bushmaster) Carbon 15. This pristine low mileage (about 300 rounds) AR weighs in at a remarkable 4.5 lbs. The stainless/carbon combination would make this a great truck or boat rifle, frankly anywhere you need a small, light, high capacity weather resistant weapon. It is chambered for 5.56/.223 and comes with one Magpul magazine. Thanks for looking. Trades: Kahr PM45, 45-70 Guide Gun, BLR in .308 or .358 (take-down would be 1st choice), maybe a 1911 or pre-lock Smith, what else might you have?
