Questions & Answers
Is the barrel at least Dimpled for lining up and installing a gas block

I don't know about the other reviewers, however, my m4 profile 16-in barrel that I purchased on this site came with a dimpled gas block area to help align and maintain that alignment by providing better grip for the non clamping type of gas block with bottom set screws. Anyways, the dimple is not necessary to line up a gas block and it only helps provide extra security for gas blocks that use bottom set screws AND line up with the dimple, once the block is in it's mounting position, firmly pressed up against the gas block shoulder of the barrel. At this point, if your 2 or 3 set screws don't line up with the dimple, like many of mine in my past, it doesn't really serve a purpose and can actually lead to the gas block not being aligned with the gas hole on the barrel, which can cause a variety of issues.

DEZ Arms' custom machined match barrels are made from 4150 chrome-moly vanadium steel made in specialized factories. Barrel are head spaced with M4 (nickel boron) feed ramped extension installed, pre drilled gas port hole with parkerized finish. Barrels are particle tested, air gauged, concentrically cut and muzzle threaded 5/8 x 24. twist to accept flash hiders/suppressors, stressed relieved, turned on center to prevent accuracy robbing distortion when the barrel heats up, and hardened to 26-33 Rc giving the barrel a long life. The 11 degree crown, polished chamber and lapped bore makes the difference! Our pulled-button rifling produces a superbly accurate bore diameter with uniform rate of twist.
