LANTAC M-SPEC556S .223/5.56 Suppressor, 6 in

The LANTAC M-SPEC556S is a .223/5.56 suppressor precision machined from 17-4 stainless steel in H900 condition. Its tubeless baffle design uses 360-degree full-penetration laser welding to help reduce thermal stress and assembly distortion during manufacturing.

The suppressor includes a 1/2-28 UNEF direct-thread HUB adapter. The adapter can be replaced with a standard 1.375×24 TPI mounting system and is designed for installation or removal with a standard armorer’s wrench barrel-nut tool.
