16" .223/5.56 OBSIDIAN ULTRA MATCH
Haven't finished the build yet, but looks good.
-
Seems good so far
Only used it once but I like it. Looks nice and shoots straight.
-
Good quality for the price
Nicely finished with a "Parkerized" appearance. Not super glossy like some Nitrided barrels. Easy install. the barrel was dimpled for a gas block or set screw type front sight base. No break in needed - doesn't copper foul at all, a real plus.
-
Excellent
Very happy with the speed and quality of my order
-
best barrel for the money 3/4 groups at 200 yards 2in groups at 600
I bought this barrel for a build I was doing found it on ebay wanted a fluted heavy barrel all of other were a 100+ really the best barrel I think its better then the colt barrel and way cheap I will be buying more

Outstanding quality Utra Match barrel
This barrel shot 1/2" groups at 50yrds sighting in with a 4x scope on a foam rifle rest using 150gr. Freedom Munitions reman ammo. I'm sure it's capable of less than than that at 100yds using a rifle sight-in vise. I have bought two of these already and will be buying more as soon as the two-tone twist Ultra Match barrels are available. I highly recommend this particular barrel for your next build. Just be sure to follow the recommended break-in procedure on CobraTac websight to properly prepare your barrel for extreme accuracy. Easy to do and you'll be very happy.
