Colt M4 Carbine 7.62x39mm 16in Matte Black Semi Automatic Modern Sporting Rifle – 30+1 Rounds

Colt M4 Carbine 7.62×39mm 16 Inch Semi-Automatic Modern Sporting Rifle – AR Platform in Intermediate Cartridge

The Colt M4 Carbine 7.62×39mm 16 Inch Semi-Automatic Rifle is a variant of the classic AR-15/M4 platform chambered in the 7.62×39mm cartridge. It combines the familiar ergonomics and controls of the AR system with a cartridge traditionally associated with intermediate-power carbines.

This configuration is intended to provide increased intermediate-range energy and a different recoil impulse compared to standard 5.56 NATO variants.

Cartridge Characteristics

The 7.62×39mm cartridge is known for:

• Higher projectile mass compared to 5.56 NATO

• Increased close-to-mid range energy

• Generally more pronounced recoil impulse

• Effective performance in short to mid-range engagements

When combined with the AR platform, it offers an alternative ballistic profile while maintaining familiar controls and handling.

Optics and Sight Setup

This model uses a combination of:

• Magpul MBUS rear sight (flip-up backup iron sight)

• Adjustable front post sight

The flat-top upper receiver allows for optics mounting, enabling users to configure red dots or scopes depending on intended use.

Barrel and Performance

The 16-inch chrome-lined barrel improves durability and corrosion resistance, especially important for a cartridge like 7.62×39mm, which can be more corrosive depending on ammunition type.

The barrel length provides a balance between maneuverability and ballistic performance.

Handling and Ergonomics

The collapsible stock allows adjustment for different shooters and shooting positions. Despite chambering changes, the rifle maintains standard AR-15 ergonomics, including familiar magazine placement and fire control layout.

At approximately 5.95 lbs, the platform remains relatively lightweight for its caliber class.
