SIG Sauer MCX 7.75" Handguard Assembly – Black (8901793)

This is a factory SIG Sauer handguard assembly for the SIG MCX with a 7.75-inch barrel, finished in black. It is the OEM replacement part for short-barrel 5.56 MCX builds, so it matches the fit and finish of the handguard SIG ships on the original rifle or pistol. SIG Sauer part number 8901793, UPC 798681713417.

Factory Fit for the 7.75" MCX

Because it comes straight from SIG Sauer, this assembly is built to the same dimensions as the handguard on 7.75-inch MCX models. It is a direct way to replace a damaged or worn handguard, or to return a modified MCX to its original factory configuration.

Who It Is For

• MCX owners replacing a scratched, cracked, or lost handguard
• Owners who changed handguards and want the original SIG part back
• Builders keeping a short-barrel MCX all-factory

Confirm your barrel length before ordering: this assembly is sized for a 7.75" barrel. If you are unsure which handguard your MCX uses, check your firearm's model number against SIG Sauer's documentation.
