The Venom tactical precision ground alignment rod is used to check the alignment of your AK47's barrel threads for concentricity when installing a muzzle device such as the Venom Antidote muzzle brake.
Not all barrel threads are machined to the same standard. Check the barrel thread to brake alignment concentricity by threading the brake on to the barrel and using the alignment rod by passing the rod down through the brake and into the barrel bore. There should be equal clearance all the way around the circumference of the rod.
