    thank's

  2. Getting ready to start my first ar build and want to stick with an a2 block. I'm looking at my current ar while watching this and am wondering if anything on the barrel has to be drilled out before the pins can be inserted? it look like the pins recess into the barrel, any tips on how to do it?
