Diligent Defense CBAH Muzzle Device Features The Diligent Defense CBAH Muzzle Device is CNC machined from 17-4 PH stainless steel and heat treated to H900 condition for exceptional strength hardness and corrosion resistance through sustained fire and repeated suppressor attachment cycles on .30 caliber and smaller platforms. The 5/8x24 thread pattern provides direct compatibility with common larger-bore threaded barrels and the .900x24 suppressor mount output interfaces with the DDC Zilch Q Plan B and Rearden Atlas among other compatible .900x24 suppressor mounts. A .33 internal bore accommodates .30 caliber and smaller projectiles with proper clearance for reliable baffle-strike-free suppressor operation. The 360-degree port orientation is specifically designed to minimize the need for timing shims during installation simplifying setup and reducing the hardware required to achieve a properly timed installation. A 13/16 rear hex provides a positive wrench engagement surface for controlled installation and removal torque without risk of slipping or marring. At 1.45 and approximately 1.9 oz. the CBAH adds minimal length and weight to the muzzle end while providing a compact blast management and suppressor mounting solution.
