DPMS Kitty Kat 300 Blackout Upper Receiver

The DPMS Kitty Kat represents a purpose-built upper receiver assembly for shooters seeking a compact, effective platform in 300 Blackout. This is a complete upper—everything you need except the lower receiver.

Barrel Specifications

The heart of this upper is a chrome-moly vanadium steel barrel chambered in 300 Blackout with a 1:7 twist rate optimized for subsonic and supersonic ammunition. The barrel features:

• 7.5" length for compact handling and velocity
• Nitride finish for corrosion resistance and durability
• M4 barrel extension for reliable feeding
• Pistol-length gas system for balanced cycling
• A2 flash hider to manage muzzle signature

Handguard and Sighting

A 4-inch knurled tube free-float handguard provides a solid mounting platform while keeping the barrel free from contact. The R-marked front sight gas block offers a traditional aiming reference, while the A1 rear sight aperture provides a proven sight picture.

Upper Receiver

Forged from 7075-T6 aluminum and machined to MIL-SPEC dimensions, the C7 upper is hard coat anodized for durability. It includes forward assist and dust cover for reliable operation in field conditions.

Bolt Carrier Group

The mil-spec bolt carrier group features shot-peened Carpenter 158 steel construction with a chrome-lined, phosphate-coated M-16 profile carrier. The gas key is hardened to USGI specifications and secured with Grade 8 screws, then staked per military specifications for reliability.

This upper assembly delivers proven performance in a compact package ideal for 300 Blackout shooters.
