Aim7 MAGIK-S Tube – Steel Bravo/HUB Modular Tube (1.375×24) | 3.5″ , 4.5″, 5.5″ Length | 1.55″ OD

Description

The Aim7 MAGIK-S Tube is an ultra-durable, modular tube component engineered for structural rigidity, true bore concentricity, and broad platform compatibility. Precision CNC-machined from SUS303 stainless steel with a protective black finish, it provides exceptional thread integrity, corrosion resistance, and repeatable alignment across demanding setups.

Designed around the industry-standard Bravo / HUB (1.375×24) thread pattern on both interfaces, the MAGIK-S Tube allows seamless integration with standard Bravo-pattern mounts, adapters, end caps, and modular system accessories. Available in 3.5″, 4.5″, and 5.5″ lengths to fit your precise internal volume and spacing requirements.

KEY FEATURES:

• Universal Bravo / HUB Pattern: Features 1.375×24 TPI internal threads on both ends for universal modularity across compatible mounting systems and accessories.
• SUS303 Stainless Steel Construction: Precision CNC-machined from solid SUS303 stainless steel with a robust 0.11″ wall thickness for superior strength, durability, and corrosion resistance compared to aluminum alternatives.
• Bore Alignment & Concentricity: Machined to strict tolerances to ensure true concentricity and repeatable alignment with your host setup.
• Durable Black Finish: Protective surface treatment minimizes glare and resists environmental wear.
• Modular Length Selection: Available in 3.5″, 4.5″, and 5.5″ configurations to optimize build volume and spacing.

Mechanical Strength & Rigidity

• Yield & Tensile Strength: Typical yield strength is ~240–310 MPa (35–45 ksi) and ultimate tensile strength is ~620–690 MPa (90–100 ksi). It possesses solid structural rigidity, easily resisting physical denting, drop impacts, and deformation under typical blast pressures, far outperforming 6061-T6 aluminum.

• Hoop Stress & Wall Thickness: At a 0.11″ wall thickness with a 1.55″ OD, SUS303 provides substantial mass and hoop strength to contain hot gas concussion in linear compensators and blast shields across common calibers (such as 5.56/.223, .300 BLK, and 9mm/PCC).

Thread Integrity & Wear Resistance

• Thread Life: The inclusion of sulfur provides dry lubricating properties during machining, resulting in exceptionally clean, burr-free threads ($1.375\times 24$ HUB/Bravo pattern).

• Galling Resistance: While all austenitic stainless steels carry a risk of thread galling under friction, 303 galls somewhat less readily than 304. Applying anti-seize or high-temperature thread grease is still recommended for frequent assembly/disassembly cycles.

Heat & Blast Resistance

• Continuous Thermal Exposure: Can handle sustained temperatures up to 800°C–900°C (1,470°F–1,650°F) without structural softening or losing tensile strength, making it far superior to aluminum during rapid strings of fire.

• Erosion: Resists direct flame wash and unburnt propellant erosion significantly better than aluminum, though slightly less erosion-resistant over extreme round counts compared to heat-treated 17-4 PH stainless steel or 4140 chromoly.

COMPATIBILITY & NOTES:

• Interface: Compatible with industry-standard 1.375×24 (Bravo / HUB pattern) modular components, adapters, and mounts.
• Host Setup: Final bore clearance and caliber compatibility depend on your choice of mount and bore/end cap setup (components not included unless explicitly stated).
• Includes: One (1) Aim7 MAGIK-S Tube in selected length (tube only).
• Fabrication Note: SUS303 is selected for excellent thread machining and tight tolerances; it is not recommended for critical welding applications.
