That's similar to the nut I have on the 6x45 upper. https://www.midwayusa.com/product/100328...inum-matte
It can not touch by being perfectly aligned and going straight through the center. If it touches, vibration will travel down gas tube into the block and into the barrel. Its possible - they had it centered pretty damn well on the factory assembled upper. I'm going to check to see if its centered before my next range trip and if I don't get anywhere playing around with COAL, I may bite the bullet and buy an ALG handguard and nut for it. Would be nice to use it with my Atlas bipod anyways and I do have another use for the Harris.
