holy....! I hadn't checked the price in a while...I would say yes on the 6" fluted, and the M4 options.

You're getting into a price range that will get you a much, much better barrel (see Hammerhead, or most carbon options). It would be better to drop or save and drop an additional 30-40 for a kit in the long run.

If you really like one of these try ebay or another supplier of opsgear barrels.

Oh yeah, they are very durable, you won't be able to wear it out. The finish on the inside is crystal.
