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.
Purchased this to upgrade my old basic Colt M4 and couldn't be happier. Once you clear the barrel of the Delta ring, stock plastic rail, sling slip and metal ring behind gas black this goes on like a glove. Excellent upgrade.
MLOK 12IN CUT OUT RAIL was as straight forward install. Great quality, finish and nice way to keep the front sight post and utilize the standard milspec barrel nut. Finish is close or is the same as my LE6920. Thanks Centurion.
I installed a C4 MLOK FSB rail this weekend on an old Colt 6920 that had been relegated to the back of my safe. The lightweight nature of this rail, impeccable build quality, and flexibility afforded by the MLOK slots and extended FSB rail completely transformed my old carbine. I could not be more pleased. And as always, Centurion Arms customer service was second to none. This is the best Centurion Arms rail yet.
