The CMMG ZEROED Banshee MkG 45 ACP SBR is a short-barreled rifle delivered with a ZEROED 46 suppressor already matched to it, finished in Midnight Bronze Cerakote (brand part no. 45AEA92-MB). Most .45 ACP loads are subsonic straight from the box, so a suppressed .45 carbine is about as quiet as a centerfire firearm gets, and CMMG built this one around that fact rather than treating the can as an afterthought. The 6.5-inch barrel sits inside a 10-inch oversized M-LOK handguard that shrouds the suppressor, keeping overall length short while hiding the heat. CMMG’s Radial Delayed Blowback system tames the impulse that normally makes blowback pistol-caliber guns unpleasant. A Glock-pattern magwell in the MkG lower means the .45 ACP magazines already in your range bag will run it.

Key Specifications

• Chambered in .45 ACP, a cartridge that is naturally subsonic in most factory loadings and therefore well matched to suppression.
• The 6.5-inch black nitride threaded barrel keeps the package short while providing the muzzle threads the suppressor mounts to.
• Capacity is 13+1, fed through a Glock-pattern magwell that accepts common .45 ACP magazines.
• An included ZEROED 46 suppressor ships matched to the host rather than sourced separately.
• The B5 Systems Bravo stock provides an adjustable shoulder position on a genuinely compact platform.
• CMMG’s Radial Delayed Blowback operating system smooths the recoil impulse typical of blowback pistol-caliber carbines.
• The receiver is Midnight Bronze Cerakote over aluminum with a full-length Picatinny top rail for optics.
• A 10-inch oversized M-LOK handguard shrouds a suppressor up to 1.58 inches in diameter.
• The ZEROED 60/90 ambidextrous safety selector lets either hand work the gun without shifting grip.
• Three SD-style silicone handguard covers snap into the M-LOK slots to insulate hands after sustained fire.

Frequently Asked Questions

Is this an NFA item? Yes, and it involves two of them. As a short-barreled rifle it is a Title II firearm, and the included ZEROED 46 suppressor is a separately registered Title II item, so each requires its own approved ATF Form 4 and transfer through an NFA-licensed dealer.

Why is .45 ACP a good suppressed cartridge? Standard .45 ACP loads are already subsonic, so there is no supersonic crack to suppress and the can only has to manage muzzle blast.

What magazines does the MkG lower accept? It uses a Glock-pattern magwell, so common .45 ACP Glock-pattern magazines feed it directly.

Buy the CMMG ZEROED Banshee MkG 45 ACP SBR

This is a Title II item regulated under the National Firearms Act, and because the suppressor is included it represents two registered items on two separate applications. Purchase requires an approved ATF Form 4 for each, no federal transfer tax, and transfer through a licensed NFA (SOT/Class 3) dealer; ATF approval on most individual eForm 4 filings now comes back in days, and trusts take a little longer. A short, quiet, soft-shooting .45 that runs the magazines you already own is a rare combination, and the ZEROED package removes the usual guesswork of pairing a host to a can. Order through CMMG‘s lineup and our Lubbock, Texas team will walk you through the transfer process.
