CAT ST Super Thug 5.56 Suppressor - 1.375x24 HUB - Titanium

The CAT ST Super Thug 5.56 Rifle Suppressor gives users a generic 5.56 silencer that works across all traditional 5.56 barrel lengths. Built for users who want strong reductions in sound, flash, blast propagation, toxic fume, and wear, this rifle suppressor is CAT's baseline 5.56 solution.

Features:

• Designed for 5.56, max caliber 6 ARC
• SBX internal geometry
• 1.60" diameter
• PVD finish
• Optimized for 14.5" AR-15 rifles
• Titanium (Ti-C) construction, 9 oz
• 6" long
• Minimum barrel length of 11.5"
• 1.375x24 HUB compatible, no mount included

The ST is CAT's first generic 5.56 suppressor, built to run across short, mid, and full-length 5.56 barrels without platform-specific tuning. Its SBX geometry is tuned to manage the pressure spike of 5.56, for a suppressor that runs quieter, cooler, and flatter with much less forward concussive overpressure.

The refined flow path stabilizes back pressure for reliable cycling without tuning.

CAT builds suppressors in-house with a focus on reducing sound, flash, blast, and toxic fume in compact, durable designs.
