"This is a great barrel if you want to stand out from the crowd. Installed this in a Dboys m4 metal body and it looks fantastic! The matte silver finish is great along with the dimples, but can scratch easily when/if your installing a free float rail. My only problem was there was only one spot that they made smooth to install a gas block. If you don't have a rail over 10 inches you should be fine(mine was 12 and it cover the spot. My rail didn't require a gas block anyways).

-Good quality metal and finish
-Matte silver
-Unique look
-14mm CCw

-Scratch easily(scratches can be rubbed off)
-May stand out a little in the woods(If your really concerned about your camo, just wrap it in some camouflage.

All in all, If you want to stand out from the crowd in style get this barrel!
