Description

MAGIK-S Tube – Steel Bravo/HUB Modular Tube (1.375×24) | 2.5″ Length | 1.55″ OD

The MAGIK-S Tube is a modular tube component built for strength, alignment, and broad compatibility. Machined from SUS303 stainless steel with a black finish, it offers a rugged look with good corrosion resistance.

Specs

  • Length: 2.5 in

  • Outer Diameter: 1.55 in

  • Tube Thickness: 0.11″
  • Thread Interface: 1.375×24 (1-3/8×24) Bravo / HUB standard

  • Material: SUS303 Stainless Steel

  • Weight: 5.1 oz
  • Finish: Black

Compatibility

  • Uses the industry-standard Bravo/HUB (1.375×24) interface for compatibility with many Bravo-pattern modular components and mounting systems.

  • Caliber/host setup depends on the mount/adapter and bore size you choose (not included unless stated in the listing).

Common host thread examples (with the correct mount/adapter)

  • 1/2×28 (commonly used on many 9mm hosts / .45 with the appropriate system)

  • 5/8×24 (widely used on many .30 cal hosts)

Notes

  • Please verify threading, bore size, and system compatibility with your specific build before purchase.

  • Tube only unless otherwise stated.

Typical mechanical properties (room temp, annealed — )

  • Tensile strength: ~500–750 MPa

  • Yield strength (0.2%): ~190–300 MPa

  • Elongation: ~25–40%

  • Hardness: ~≤ 200 HB (often around mid-B range on HRB)

Physical properties

  • Density: ~8.0 g/cm³

  • Elastic modulus: ~190–200 GPa

  • Melting range: ~1400–1450°C

  • Thermal conductivity: ~16 W/m·K (ballpark for 300-series)

Practical notes for your use case (tube/muzzle parts)

  • Great choice when you want nice threads, a clean finish, and fast machining

  • If the part will see harsh salt exposure or heavy heat/erosion, some people prefer 17-4PH, 4140/4150, or 416R/410, depending on design goals

  • Welding: possible but not ideal; 303 is generally not recommended for critical welds
