Nice Colt LE6921HB M4 "SOCOM" heavy barrel with A2 flash hider and sling ring. This barrel does not have a scratch on it and is in excellent to like new condition. This barrel has had about 400-600 rounds through it all in semi-auto mode. The price is firm and a steal at $299.00 plus shipping. Pics and references will be available to a serious buyer.
