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

300BLK earned its reputation in platforms just like this — short, compact, and purpose-built. The ZEROED BANSHEE Mk4 Upper Group gives you the Direct Impingement reliability of the Mk4 platform with a ZEROED Faux Suppressor that tucks inside the oversized 11" M-LOK handguard. The result is a suppressor-profile build that looks the part without the NFA tax stamp or suppressor regulations. Drop it onto any standard Mk4/AR15 lower receiver and you're ready to run. 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.
