SIG MCX Rattler LT Suppressor-Compatible M-LOK Handguard

The SIG factory MCX Rattler Suppressor-Compatible Handguard is the LVAW-pattern conversion handguard for the SIG MCX Rattler LT 6.75" .300 BLK. The Rattler LT is the civilian descendant of the SOCOM Low Visibility Assault Weapon (LVAW), the suppressed sub-PDW lineage used by JSOC units including DEVGRU and CAG for ultra-compact covert roles. The defining LVAW design move is fitting the entire suppressor inside the handguard outline, so the rifle in covert-bag configuration looks like a longer-barreled gun rather than a short pistol with a can hanging off the front.

The factory shroud that ships on the standard MCX Rattler LT does not have the internal diameter to clear a typical 5/8x24 .300 BLK suppressor. This handguard replaces it with a wider aluminum M-LOK tube engineered specifically to clear the SIG SLH (Subsonic Light Hush) and SLX-style direct-thread suppressors, plus most third-party 1.5"-OD .300 BLK cans. The result is a Rattler LT that runs a full-length suppressor with the same overall length as an unsuppressed Rattler LT with the standard shroud.

M-LOK slots along the sides provide mounting points for a Surefire mini-scout, an IR laser, or a hand-stop forward of the magwell. The handguard is drop-in on the standard Rattler LT upper and uses the OEM takedown hardware. Available factory direct from SIG and from major SIG retailers.
