AIM7 MAGNUS-S MAGIK Bravo 4″ Modular Assembly + H-3 1/2 x 28

(1.375×24 HUB / Bravo Compatible Modular System)

The AIM7 MAGNUS-S Bravo 4″ Assembly is a modular Bravo-pattern tube system constructed from strong, lightweight aluminum components. Designed for precision alignment and compatibility, each section uses the industry-standard 1.375×24 HUB / Bravo thread interface.

This assembly includes the MAGIK 2.5″ Tube, the 1.5″ Bravo Spacer,—a tapered internal alignment cone designed for modular builds.

All components are fully compatible with Aim7 MAGIK, Aim7 MATRA, and other Bravo-pattern modular systems.

Adapter options:

• ASR Taper Mount 1-1/8 X 12  (Can be used as Barrel Shroud also)

• And many more Aim7 modular adapters are available

 Material Overview: SUS303 Stainless Steel

This muzzle brake is manufactured from SUS303 (equivalent to AISI 303), an austenitic stainless steel known for its ease of machining and corrosion resistance.

Property	Description
Composition	Fe, 17–19% Cr, 8–10% Ni, ~0.15% S, ~1% Mn
Machinability	Excellent (better than SUS304)
Corrosion Resistance	Good, slightly lower than SUS304
Tensile Strength	Moderate (500–750 MPa)
Weldability	Poor (due to sulfur content)
Magnetism	Non-magnetic (annealed condition)

SUS303 is a good choice for civilian semi-automatic rifles and moderate use, but it is not intended for extreme military-grade abuse.
