Description
AIM7 4″ CNC Aluminum Modular Comp Spacer HEX (1-1/8 x 28 Alpha)
Upgrade your modular blast deflector or linear compensator setup with the precision-machined AIM7 ARCHER 4″ Modular Comp Spacer HEX. Crafted from rugged 6061-T6 aerospace aluminum and treated with a protective black hardcoat anodized finish, this 4-inch extension allows for seamless length customization and internal volume expansion within your muzzle assembly.
Featuring an integrated hex drive geometry for secure tool purchase, proper torquing, and effortless disassembly after high-round-count carbon buildup, this spacer sports a sleek 1.285″ outside diameter engineered to slide cleanly under slimline rail systems while providing maximum structural concentricity.
Key Features & Performance
- Integrated Hex Wrench Flats: Engineered with external flats for standard armorer wrench or socket engagement, ensuring slip-free torque application and hassle-free removal even after heavy carbon exposure.
- Alpha Standard Interface: Precision CNC-machined 1-1/8×28 TPI (1.125×28) internal and external threads ensure seamless integration with popular Alpha-pattern adapters, blast shields, and front caps.
- Added Volume & Clearance: Provides a true 4.0″ of modular linear extension to tailor overall compensator length, clear extended handguards, and optimize internal expansion.
- Featherweight 6061-T6 Aluminum: Weighs just 2.5 oz to preserve balance and swing speed without compromising operational strength or heat dissipation.
- Hardcoat Anodized Armor: Type III matte black hardcoat anodizing delivers exceptional resistance to scratching, surface wear, and corrosive propellant gases.
