Why Choose This BANSHEE MK4?

.300 Blackout Versatility (Supers & Subs)

From supersonic hunting/defense loads to subsonic ammunition for reduced blast, .300 BLK allows you to tailor recoil, sound, and terminal performance to your environment—especially effective when paired with a compatible muzzle device or suppressor (where legal).

12.50" Black Nitride Barrel = Balance & Durability

The medium-taper profile promotes consistent harmonics while black nitride hardens the surface for excellent corrosion resistance, easy cleaning, and long service life under high round counts.

EML 7" Free-Float M-LOK® Handguard

Short, slim, and slick. The 7-inch length keeps your support hand close for compact control while providing M-LOK® real estate for a white light, hand stop, QD cups, and cable management—without adding weight or bulk.

Coyote Tan Cerakote® + Optics-Ready Rail

The durable Coyote Tan finish resists abrasion and cleans up easily, while the full-length Picatinny top rail makes it simple to mount a micro red dot, prism, or LPVO.

CMMG ZEROED™ Ergonomics

The ZEROED™ grip offers a comfortable angle and confident texture for steady control, faster returns to target, and improved comfort across long training days.

*Thread Pitch: .300 BLK barrels are commonly 5/8×24; always verify the exact pitch on your serialized spec card before purchasing muzzle devices or mounts.

Small components like trigger style, charging handle, and included muzzle device can vary by production run or retailer bundle. Check the box label for definitive configuration.

What You’ll Notice on the Range

Soft, Trackable Recoil

.300 BLK’s impulse is predictable and controllable, keeping your sight picture stable for faster follow-ups—especially with a tuned muzzle device or suppressor (where legal).

Free-Float Consistency

The EML handguard isolates the barrel from sling/barricade pressure for repeatable point of impact and confidence when changing positions or accessories.

Smart Accessory Placement

The compact rail makes it easy to keep lights and switches close to centerline for clean cable routing and reduced snag risk.

Ideal Use Cases

• Home & Property Defense: Compact handling with robust .30-cal bullet selection

• Low-Light Training: Mount a weapon light and maintain control with the short EML forend

• Suppressed Use (Where Legal): Subsonic-capable caliber + threaded muzzle for flexible setups

• Range & Classes: Durable finish and AR-15 familiarity for high-volume reps

Smart Setup Recommendations

• Optic: Micro red dot for speed; consider an LPVO 1-6× if you need more reach

• Light: Compact M-LOK® weapon light with a momentary/remote switch

• Sling: Two-point QD sling; add QD cups where your stance demands

• Muzzle Device: Confirm thread pitch before selecting a brake, comp, or suppressor mount

• Ammo: Zero with your intended role (supersonic vs. subsonic) and test function across loads

Frequently Asked Questions

Q: Will this run both subsonic and supersonic .300 BLK?
A: Yes—.300 BLK is designed for both. For best results, tune your setup (muzzle device/suppressor and ammo) and confirm reliable cycling with your chosen loads.

Q: Is the barrel threaded from the factory?
A: Yes. Verify the thread pitch (commonly 5/8×24) on your spec card before purchasing devices or mounts.

Q: What magazines should I use?
A: Standard AR-15/STANAG magazines are typical for .300 BLK. Always mark your mags to avoid 5.56/.300 BLK mix-ups and test for reliable feeding.

Q: Can I run it suppressed?
A: Generally yes, where legal. Confirm thread pitch, choose a compatible mount, and function-test with your intended sub/super loads.
