Description
The 7.62×39 cartridge and standard AR magazines have never played nicely together. That steep case taper wants a curved mag, and straight AR mags just don't cooperate. CMMG fixed it the sensible way with the Banshee Mk47: build a mid-size AR receiver set with a magwell cut for AK-pattern magazines, the mags this cartridge was designed around in the first place. Rock in a 30 round PMAG like you would on any AK and enjoy the feeding reliability that Frankenstein 7.62×39 ARs can only dream about.
Inside the Banshee Mk47 Build
The Mk47 sits between CMMG's AR-15 and AR-10 size platforms, with billet 7075-T6 aluminum receivers and beefed up internals, including CMMG's PowerBolt technology, to handle the cartridge without turning the gun into a boat anchor. The 8 inch 4140CM barrel wears a salt bath nitride finish, spins a 1:10 twist, and comes threaded 5/8×24 with a ZEROED linear compensator up front to push blast forward instead of back at you. A pistol-length gas system keeps this direct impingement gun running from a barrel this short. All in, you're looking at right around 6 pounds and under two feet of overall length.
Set Up Right From the Factory
CMMG didn't skimp on the small stuff. You get their ambidextrous 60/90 degree safety, an ambi charging handle, ZEROED pistol grip, and the quick-deploying RipBrace that extends with a straight pull, no fumbling with adjustment buttons. The EML M-LOK handguard gives you slots on both sides and the bottom plus a full-length Picatinny rail on top, so lights, lasers, and a red dot all have a home. The flat top is optics ready, so plan on mounting your sight of choice.
Why Pick the 8 Inch Mk47 Banshee
This is the shortest and lightest 7.62×39 gun CMMG makes, and it lands squarely in truck gun and home defense territory. You get 30 rounds of hard-hitting 7.62×39 in a package that swings fast in tight spaces, wrapped in a sharp Tungsten Cerakote finish and backed by CMMG's lifetime quality guarantee. AK punch, AR manners, no compromises on feeding.

Frequently Asked Questions
What magazines does the CMMG Banshee Mk47 use?
It takes AK-pattern magazines, the same mags that run in an AK-47, and ships with a 30 rounder. This is the whole point of the Mk47 design, since the 7.62×39 cartridge was built around the curved AK magazine and feeds far more reliably from it than from a straight AR mag. Magpul AK PMAGs are a popular and proven choice.
Does the Banshee Mk47 come with sights or an optic?
No, it ships optics ready with a bare Picatinny rail up top. Most owners run a red dot on a pistol like this, which pairs well with the short barrel and close to mid-range role. Backup irons are also an easy add if you want them.
Is the 8 inch barrel enough for 7.62×39?
The 7.62×39 cartridge holds up better out of short barrels than smaller rifle rounds, which is a big reason it's popular in this format. You still get solid energy at practical distances, making it a strong pick for home defense or a compact range gun. The ZEROED linear compensator also helps direct muzzle blast forward, which your neighbors at the range will appreciate.
Can I put a suppressor or different muzzle device on the Mk47 Banshee?
Yes, the barrel is threaded 5/8×24, a common thread pitch for .30 caliber muzzle devices and suppressor mounts. The factory ZEROED linear comp comes off easily if you want to swap in something else.
