Due to the MK12 profile front end extended .750in profile forward of the gas block, significant marring of the finish will occur from installation/removal of the gas block (whether pinned or set screw), no matter the finish (as the original MK12's were.)
Because of this, all pinned barrels will need to have a barrel nut of your choosing (or send yours in) and be Cerakoted with the barrel nut and gas block in place.

Custom Cerakote Disclaimer:
Custom Cerakote is completed per order. Our Cerakote room runs one color at a time so your ship date will be subject to the color rotaion at the time the order is placed. You will receive an email confirmation once the item has actually been packaged to ship.
Cerakote items are not guaranteed to match separate batches or Cerakote completed by outside parties. While we strive to keep our mix uniformed for our own products, we can't say for certain what Walter and Jesse cooked up in their lab out in Albuquerque.
