Like Wonder Bread, there’s a special kind of magic in CAT’s White Bread (WB). This 5.56mm suppressor showcases a significant advancement in silencer technology with its SURGE BYPASS pressure system. This pressure system manages the flow of gases more efficiently over a reduced length, minimizing both sound and felt recoil. This can uses Laser Powder Bed Fusion (LPBF) engineering and internal structuring to channel gases and effectively produce superior high pitch, high frequency noise reduction while minimizing pressure wave propagation for the shooter. The CAT WB is known for its exceptional durability, being made from high-grade materials and subjected to rigorous testing. It can withstand extreme temperatures, corrosion, and the stresses of rapid firing, making it suitable for both military professionals and civilian enthusiasts.

Full Auto or High Rates of Fire (greater than 30 rounds per minute) are expressly discouraged, unless in life threatening self-defense situations, on the titanium version of this silencer. The titanium version is a super lightweight, high performance suppressor dedicated to Low Rates of Fire. You should not exceed a maximum service temperature of approximately 650°F (343°C). This model is more of a Formula 1 race car versus the M1A2 Abrams main battle tank. Both models will get you from point A to point B… they just do it two different ways. If you’re looking for something with tracks instead of tires, check out the 718 Inconel version of this silencer!
