I picked up a barrel at the Tulsa gun show that I think is one of the Colt M4 Heavy Barrels. It is marked “C MP 5.56 NATO 1/7“. It is 14.5” long, has the bayonet lug and has a threaded muzzle. It has the M4 profile ahead of the front site base, but is heavy under the handguards. It has two flat areas on either side of the barrel behind the front site base. Can someone verify that this is indeed a Colt M4 Heavy Barrel? TIA

I'm not a Colt expert, but it looks like you have one of the M4 HB's according to a thread I read recently. I have a pic of the M4 HB's from that thread, and your barrel is exactly like the one pictured, but my photo server wouldn't accept the photo file type. I believe the flats were added to facilitate the mounting of a M203, someone please correct me if I'm wrong. One of the experts will be along shortly....so I'll leave any further comments up to them!

Yours is the heavy barrel. The side cut is a sure indicator. The lighter barrels are thinner, and smooth to the M-203 cut. Edited for picture: [red]This pic stolen from KevinB[/red] [img]http://photos.ar15.com/WS_Content/ImageGallery/IG_LoadImage.asp?iImageUnq=3088[/img]

Great find :-) I've been looking for another one for nearly a year, and no one seems to be able to get those things. -Cap'n

It is the real deal. How much did it cost you?

Thanks for all the info guys. Would you believe I got it for $425.00 and that price included the Colt M4 Handguards as well! At that price I wasn't sure if this was a true Colt M4 HB, but I guess the guy who was selling it didn't know what he had.
