Bitter24 Report post Posted August 18, 2013 Looking to trade a AI .308 (7-62x51MM LP/10) barrel with AI brake for a flat top AR upper with BCG. Can send pics of the barrel to email or phone. I got the barrel second hand and to my knowledge and looks of it, it hasnt been fired. If it does have rounds down her it isnt many looks spotless. Barrel measures 20" from end to end plus brake. It is 18" from end of barrel threads to the crown. Need more info ask away. Let me know what you got? Thanks Brian Share this post Link to post Share on other sites
