Suppressed Upper Group, ZEROED BANSHEE, Mk4, 300BLK, 6.5"

300BLK was practically designed to be suppressed, and the ZEROED BANSHEE Mk4 Suppressed Upper Group leans into that heritage completely. Running on Direct Impingement, the 6.5" barrel pairs naturally with the included ZEROED 30 suppressor, which tucks neatly inside the oversized 11" M-LOK handguard. Compatible with standard Mk4/AR15 lower receivers, this upper group is the easiest way to turn any Mk4 lower into a purpose-built suppressed .300 BLK platform. 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.
