Radical Defense’s MK-22 Advanced Sniper Rifle (ASR) Integrally Suppressed Barrel Conversion System (IS-BCS) is two pounds lighter and between four and eight inches shorter than the currently fielded system. The IS-BCS increases accuracy (we garauntee .25 MOA improved accuracy over factory spec) and eliminates the potential for dangerous and system-compromising suppressor baffle strikes. The barrel uses a revolutionary monolithically machined design to create a system that outlasts the existing system while creating hearing-safe conditions and the tactical signature reduction needed for success on the battlefield.
