I need to neuter the FSB on the FN A2 upper i just received, file down the bayo lug to be AWB compliant. Is there a finish I can apply to cover any bare metal after I am done filing? I am not even sure what the finish is, it looks like parkerizing on the barrel, not sure what is on the FSB but it is worn on the edges.
Thanks, Ken |
