CMMG BANSHEE MK4 5.56 | 10.5 in | 30rd

The CMMG BANSHEE Mk4 is a compact AR-style pistol built on the Mk4 platform and chambered for .223 Rem/5.56 NATO. With a 10.5-inch barrel and full-length M-LOK slots on the handguard, it balances short‑package maneuverability with carbine-style performance. The package includes a RipBrace pistol brace, a single 30‑round Magpul PMAG, and CMMG ZEROED controls and trigger components. For optics consider a Trijicon MRO reflex sight (well under $1,000) mounted to the Picatinny footprint for fast, reliable sighting in short-barrel applications.
