Description

The CMMG A0B Mk4 AR-15 rifle, now enhanced with the CMMG Zeroed 556K suppressor and Vortex Optics SPARC AR 2 MOA red dot sight, forms an outstanding suppressed optics-ready package tailored for 5.56mm NATO/.223 Remington versatility. The rifle's 16.1-inch 4140CM SBN barrel with 1:7 twist and rifle-length direct impingement system pairs perfectly with the compact Zeroed 556K suppressor-replacing the included Zeroed muzzle brake (which remains provided)-to deliver substantial noise reduction, minimal muzzle flash, and improved control for faster, more accurate follow-up shots. The premium TriggerTech AR-D 2-stage trigger ensures crisp performance, while the M-LOK handguard offers flexible mounting options, and the Armor Black Cerakote finish with B5 Systems stock provides rugged durability and ergonomic comfort in a lightweight 6.5-pound, 41-inch platform.The Zeroed 556K suppressor adds just 5.5 inches (5.2 inches without mount) and 13.5 ounces (11 ounces without mount) with its heat-treated 17-4 stainless steel construction, nitride finish, and tubeless laser-welded baffles for excellent sound suppression on 5.56mm and compatible calibers. Full-auto rated, user-serviceable, and HUB-compatible with included 1/2x28 and 5/8x24 direct thread mounts, it maintains the rifle's balance for dynamic handling in training, home defense, or tactical use. Topped with the Vortex SPARC AR 2 MOA red dot, this bundle gains rapid target acquisition through its parallax-free 2 MOA bright red dot, unlimited eye relief, and multi-height mount compatible with AR platforms.The Vortex SPARC AR features 10 daylight-bright brightness settings (including night-vision compatible low levels), a 50,000-hour AAA battery life with 12-hour auto-shutoff, fully multi-coated lenses for clear sight picture, and rugged, shockproof/fogproof/waterproof construction in a compact 2.9-inch, 7.5-ounce body with 90 MOA windage/elevation adjustments. This complete setup combines CMMG's in-house quality manufacturing with Vortex's legendary reliability and lifetime VIP warranty, delivering a suppressed, red-dot-equipped AR-15 that's ready for any scenario requiring speed, reduced signature, and precision.Build your ultimate suppressed red-dot AR-15 bundle with the CMMG A0B Mk4 rifle, Zeroed 556K suppressor, and Vortex SPARC AR sight-shop now at ARMSAGORA's retailers!Rifle Specifications:Caliber: 5.56mmOperating System: Direct ImpingmentBarrel Length: 16.1"Barrel Twist: 1:7"Barrel Material: 4140CM, SBNMuzzle Device: CMMG Zeroed Muzzle BrakeMuzzle Thread: 1/2"x28Gas Port Location: RifleGas Block: Adjustable 0.750"Handguard: M-LokFinish: Armor Black CerakoteStock: B5 Systems StockTrigger Type: TriggerTech AR-D 2-StageSafety Selector: CMMG Zeroed 60/90 DegreeMagazine: CMMG 30rdWeight: 6.5 lbsLength: 41"Suppressor Specifications: CMMG Zeroed 556kCaliber: 5.56mm, 22 ARC, 5.7x28mm, 4.6x30mmFinish: NitrideWeight:13.5 oz w/ Mount11 oz w/o mountDiameter: 1.58"Length: 5.5"5.2" w/o MountHUB Compatible: YesMaterial: Heat Treated 17-4 Stainless SteelMinimum Barrel Length: 5.7x28mm - 5"5.56mm - 10.5"Mount: 1- 1/2"x28 TPI & 1- 5/8"x24 TPI HUB MountsFull Auto Rated: YesBore Diameter: .224 CaliberRed Dot Specifications: Vortex Optics Sparc AR 2 MOA Red DotMagnification: 1xObjective Lens Diameter: 22mmReticle: 2 MOA DotAdjustment Graduation: 1 MOAParallax Setting: Parallax FreeMax Windage Adjustment: 90 MOAMax Elevation Adjustment: 90 MOADot Color: Bright RedDot Size: 2 MOAMount Type: Multi-HeightEye Relief: UnlimitedLength: 2.9"Weight: 7.5 oz
