Suppressed Upper Group, ZEROED BANSHEE, 5.7x28mm, 6.5"

5.7x28mm has proven itself as a round worth building around, and the ZEROED BANSHEE Suppressed Upper Group gives you the ideal platform to do exactly that.

The smooth Radial Delayed Blowback operating system keeps felt recoil light while the included ZEROED 556 suppressor tucks neatly inside the oversized, dad bod-ish 11" M-LOK handguard.

Compatible with both Mk4 and Mk57 lower receivers, this upper group offers serious flexibility for completing or upgrading your BANSHEE build.

Suppressor Compatibility and M-LOK Clearance

With a 1.72 inch internal diameter, the ZEROED handguard clears most modern suppressors. However, mounting M-LOK accessories in slots directly surrounding a tucked suppressor will significantly reduce internal clearance.

CMMG cannot guarantee the fitment of M-LOK accessories in these locations due to variances in suppressor and hardware sizes. Depending on your setup, modifying or shortening the M-LOK mounting screws may be required to prevent contact with your suppressor. Always verify clearance before use.
