Product Overview

The P2A PATRIOT 10.5" 450 Bushmaster SBR + Zeroed 46K Suppressor Package represents the absolute apex of short-range big-bore firearm engineering, designed specifically to address the immense gas volume and concussion of the hard-hitting straight-wall .450 Bushmaster cartridge. This premium, factory-matched tactical masterwork steps past component assemblies to deliver a completely unified, registered Short Barreled Rifle layout optimized directly from the receiver sets down to the internal buffer weights. Co-packaged alongside the modular, high-volume Zeroed 46K sound suppressor platform, this NFA-tier system tames aggressive muzzle expansion velocities into a balanced, hearing-safe tool built for rugged hunting deployment, close-range defense, and flat-shooting tracking applications.

Key Features

• Turnkey NFA Precision Integration: Pairs a dedicated close-quarters 10.5-inch Short Barreled Rifle directly with a matched high-volume suppressor, eliminating gas tuning troubleshooting and parts variance.
• Massive Big-Bore Agility: The short-profile 10.5-inch configuration preserves lightning-fast target acquisition handling and handling leverage over long hunting layouts, making it ideal for blinds or heavy brush tracking.
• Heavy-Duty Full-Auto Tracking: Features a premium M16 profile bolt carrier group built with an optimized bolt face depth specifically tailored to withstand sustained straight-wall cartridge thumping forces.
• Liquid QPQ Melonite Preservation: Full-immersion liquid nitriding imbues the 4150 CMV steel barrel core with military-grade surface hardness, defending critical lands and grooves against high gas throat erosion.
• Rigid Free-Float M-LOK Utility: Lean modular aluminum handguard provides direct attachment paths for bipods, tracking lights, and sling systems without placing physical stress on barrel accuracy harmonics.

CMMG Zeroed 46K Suppressor: Features & Advantages

The core of this package's concussive control lies within the custom-tailored CMMG Zeroed 46K Sound Suppressor. Built to handle extreme big-bore gas pressures, it tames the .450 Bushmaster cartridge down to comfortable operational levels.

Key Features:

• High-Volume Baffle Architecture: Engineered with a widened expansion chamber and aggressive internal baffling designed specifically to route and cool massive straight-wall gas payloads instantly.
• Premium Multi-Caliber Shell Design: Features heavy-duty, lightweight alloy construction rated for hard-use magnum pressures up to .45-caliber projectile diameters.
• Direct Thread Stability: Outfitted with an ultra-secure 5/8x32 direct mount thread pattern, reducing thread walk risk and ensuring dead-center alignment accuracy during prolonged strings of fire.
• Advanced Flash Hiding Endcap: Disperses secondary unburnt powder ignition at the muzzle, drastically cutting down visual flash signatures in low-light environments.

Advantages:

• Hearing-Safe Field Operation: Drops concussive straight-wall sound footprints down significantly, providing vital auditory safety for field hunters who don't want to deploy traditional earmuffs in active environments.
• Drastic Recoil Reduction: Functions as a highly efficient internal muzzle brake, capturing high-velocity escaping gas loops to turn sharp .450 Bushmaster shoulder kickback into a smooth, manageable push.
• Eradicates Lateral Shockwaves: Completely eliminates the aggressive side percussive blast wave typical of unsuppressed 10.5-inch big-bore barrels, shielding teammate workspaces and tracking positions from heavy environmental pressure shifts.
• Factory-Tuned Backpressure Management: Synchronized perfectly with the SBR's pistol gas length and heavy buffer to prevent gas-in-face blowback exposure, keeping cycling rates perfectly smooth.
