Superlative arms bleed off adjustable gas block - Superlative Arms Adjustable Bleed Off Gas Block

I received the item in good time and in good condition and installed myself on a ks47 16 inch barreled rifle. The barrel was not dimpled so I ordered a .750 kak multi position dimple jig and did it myself. Gas block aligned well after dimpling barrel and after test firing works well and ejects casings at a consistant 3-4 Oclock pattern. Very pleased with product so far and see no future problems, Thank's again for your service. Oh just to let anyone who attempts to do this themselves, the bit that comes with the kak dimpler jig will not even scratch the surface of the melonite coated barrel, will need a couple of titanium bits to accomplish, hope this helps.
