DLX working on new bolt for old Luxes February 25, 2016 Products 000DLX has confirmed to us that they are working on a version of the ICE bolt that will work in older model guns. DLX is working on the bolt but it is not a priority, over the next few months they will be focusing most of the time on getting the Luxe ICEs out the door and shipping. The new ICE bolt has redesigned air passages and uses a super slick coating that is made from ceramic. The new ceramic coating and better air flow result in lower operating pressure, better air efficiency and less maintenance. Once the bolt is in a Luxe 1.0 or OLED, the same efficiency as the Luxe ICE should be expected.
