I have a Rock River Arms 18" 1:8 twist heavy varmint barrel that I had removed from my AR 15 in favor of a lighter profile that I would like to sell. The specs of the barrel are 18" length, 1:8 twist, Varmint contour, and includes low profile gas block and gas tube. Has about 300 rounds down the tube. This barrel is very accurate and has shot pretty much any ammo that I have fed it very well. Rock River is asking $300 for this barrel and I have no idea what these are worth on the used market. I will send pics to those interested.

$200 / shipped / Offer

Also have a set of RCBS 6.5x55 swede dies that have only been used to load about 50 rounds. I bought the gun and then sold it so no longer need the dies.

$25 / Shipped

Does the AR barrel have M4 feed ramps?

That I do not know. The barrel was removed from a rock river arms varmint eop. Below are the specs from the rifle it came from.
