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.
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.
