Slick Willy!!!!

Aero has some top of the line parts and accessories. I put this in one of my builds (along with aero upper and parts and aero melonite gas tube) and this thing with the nitride finish literally slipped right on in!!!! This thing is slicker than how the government steals your hard earned money each week and calls it taxes!!!! When I say this baby’s smooth I mean it’s smoother than Jody coming over while you and bubba bueford blue are scrubbing the floors with a toothbrush…… Nitride finish is the way to go.
