I bought a 16-inch midlength barrel from a manufacturer called Alpha Omega. It is melonite coated and not the standard goverment profile.
I bought a basic low profile gas block from a LGS and when I proceeded to install the gb it would not fit. I went back to the lgs and showed one of the AR armorers there. He told me that it is possible that the melonite coating on the barrel is a bit too thick (not really a bad thing) but now I would need a different gas block.
What are my other options? I was looking at Midway and saw they have a lo-pro gas block that is slotted. It is the clamp-on style, not the usual set screw type, but I want to be sure this will work before I go ahead and buy it. If not, then I will sell/return the barrel and get a standard one. Thanks.
