I ordered a Nickel Boron bcg from 15 accessories and it came pretty quickley. I didnt think look at it right away, as I didnt have all the parts for my upper yet. Now I do, I take it out of the package and inspect it. All of the bearing races along the gas key and on the bottom of the bolt have machine marks that run perpendicular to the direction of the bolt when it will be cycling.
They are tiny little ridges, almost like the bearing surfaces were never polished.......will this eat up my upper recierver after normal cycling???? None of my other bcg have these machine marks, I am affraid to use it. I sent them an email and to my "Surprise" I never got a response........
Would you guys use the bcg or is there a way to get the races polished (it is NI Boron coated)??
