Upper Group, Unsuppressed ZEROED BANSHEE, 5.7x28mm, 6.5"
The flat-shooting, fast-cycling personality of the 5.7x28mm pairs perfectly with the ZEROED BANSHEE Upper Group's aggressive, suppressor-ready profile.
The included ZEROED Faux Suppressor tucks neatly beneath the oversized, dad bod-ish 11" M-LOK handguard — giving you the tactical look of a suppressed firearm without the NFA tax stamp or restrictions.
Running on the smooth Radial Delayed Blowback operating system, this upper is compatible with both Mk4 and Mk57 lower receivers and ready to build onto.
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.
