Im looking to buy several Colt M16A2 20inch rifle barrels. For those that dont know, Colt also used M16A2 barrels on the Colt AR15A2 Government rifles as well as the Colt Sporter Target rifles. Most of the barrels that came on the Government rifles had bayo-lugs. Most of the barrels that came on Sporter Target rifles did not have bayo-lugs. I will consider either at this time. Please contact me via e-mail through the site or direct at CLM4@EV1.NET. PLEASE do not post a response here as I dont want to babysit a thread.
