SBR, Suppressed ZEROED BANSHEE, Mk4, 5.7X28MM, 6.5"
Most personal defense SBRs compromise on something, the ZEROED BANSHEE SBR in 5.7x28mm doesn't.
From the soft and smooth Radial Delayed Blowback operating system, tucked ZEROED 556 suppressor, and full suite of ZEROED ambi controls and drop-in trigger, you would be hard pressed to find a more feature packed firearm.
The Mk4/AR15 lower receiver also means you can pair this SBR lower with just about any AR15 upper you can think of if you want to switch up calibers on a range day.
Also included are 3 SD-style silicone handguard covers that simply pop into any M-LOK slot.
ZEROED Controls: All ZEROED BANSHEEs feature our ZEROED premium controls/parts like ambi charging handle, single-stage drop in trigger, 60/90 ambi safety selector, and pistol grip.
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.
Lifetime Quality Guarantee: We aim to please, that’s why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects.
~Firearms shipping to states with magazine capacity restrictions will only ship with 10rd magazines in place of standard capacity magazines. CMMG does not address any other state compliancy requirements for further restricted states.
