MasterPiece Arms 30T Defender 9mm Luger 5.5" 30+1 Top Cocking

The MasterPiece Arms 30T Defender delivers compact firepower with top-cocking operation and threaded barrel compatibility for suppressor use. This 9mm platform combines high-capacity magazines with precise engineering for tactical applications and competitive shooting.

What Makes This Different

The top-cocking charging handle eliminates side-mounted controls that can snag on gear or interfere with optics mounting. The 5.5-inch threaded barrel accepts standard 1/2x28 muzzle devices while maintaining overall compactness. Black Cerakote finish provides corrosion resistance exceeding standard Parkerizing by 400% in salt spray testing.

Key Features

• Top-cocking charging handle for ambidextrous operation and clear sight picture
• 5.5-inch threaded barrel (1/2x28 TPI) ready for suppressors and compensators
• 30-round magazine capacity with reliable feeding geometry
• Black Cerakote finish rated for 2,400+ hours salt spray resistance
• MIL-STD-1913 Picatinny rail for optics and accessories
• Semi-automatic operation with closed-bolt firing system

Range testing demonstrates consistent 2.5-inch groups at 50 yards with quality ammunition. The platform functions reliably in temperatures from -20°F to 140°F with minimal maintenance requirements. Competition shooters appreciate the fast target acquisition enabled by the low-profile charging handle design. Law enforcement agencies have adopted similar configurations for vehicle operations where traditional side-charging systems prove cumbersome.
