DPMS Kitty Kat 5.56 NATO 7.5" Upper Receiver

DPMS Kitty Kat 5.56 NATO Upper Receiver

The DPMS Kitty Kat represents a purpose-built upper receiver assembly designed for shooters who demand reliability and precision in a compact platform. This is a complete upper—everything you need to pair with your lower receiver.

Barrel Specifications

The heart of this upper is a chrome-moly vanadium steel barrel chambered in 5.56 NATO. The 7.5" length makes this ideal for short-range work, home defense, or specialized applications where maneuverability matters. The 1:7 twist rate stabilizes a wide range of ammunition weights, from lighter varmint loads to heavier tactical rounds.

Key barrel features:

• Nitrided finish for superior corrosion resistance and durability
• M4 barrel extension for compatibility with standard components
• Pistol-length gas system for reliable cycling
• A2 flash hider to reduce muzzle signature

Handguard and Sighting

The 4" knurled tube free-float handguard keeps the barrel isolated from external pressure, promoting accuracy. The R-marked front sight gas block serves double duty as both a gas block and front sight reference. An A2 rear sight aperture provides a proven sighting solution.

Upper Receiver

Forged from 7075-T6 aluminum and machined to MIL-SPEC tolerances, the C7 upper is hard coat anodized for maximum durability. It includes forward assist and dust cover—the features that make an AR upper complete and functional.

Bolt Carrier Group

The mil-spec bolt carrier group is built to exacting standards. The bolt is shot-peened Carpenter 158 steel with a hardened gas key fastened with Grade 8 screws and staked per military specification. The carrier itself is 8620 steel with an M-16 full auto profile, chrome lined and phosphate coated for reliability and longevity.

This is a no-compromise upper receiver for serious shooters.
