All EliteIron Suppression Systems' tubes are fabricated from non-magnetic, 304 stainless steel and trued for concentricity. It has been clearly demonstrated that aluminum tubes cannot provide the durability required of battlefield environments. The internal parts, made from 17-4 PH stainless steel, are CNC-machined from solid billets and 100% TIG (Tungsten Inert Gas) welded for added strength and toughness. The internal baffle design is a heavily modified so-called "K"-type. Knurled bands at the attachment end of the sound suppressor aid in the installation and removal of the unit and serve as tactile locator bands in subdued light. All of the units' components are individually checked prior to assembly, which is entirely by hand. CeraKote^TM finish is used on all EliteIron sound suppressors, unless the customer requests a sandblasted finish. The EliteIron suppressor product line-up as picture below is: Alpha .50, Bravo .30, Bravo 1 .30, CQC1 .22/5.56, Delta .22, Echo 22lr/5.7 x 28mm, Sierra .338 Lapua, Sierra SD .338 Lapua, Windtalker .375/.408/.416, Bravo SD .30, and Black Reign .45 ACP.
