The DPMS Kitty Kat is a complete AR-platform upper chambered in .300 AAC Blackout with a compact 7.5-inch barrel (DPMS part no. DP51655170308). The barrel uses an M4 barrel extension, a 1:8 twist rate, and a pistol-length gas system sized to cycle reliably at this short barrel length. (Note: the source listing gives conflicting barrel-finish information — phosphate in the descriptive text vs. black nitride in the structured spec field — so no single finish claim is asserted here; confirm the exact finish from product photos if that detail matters to you.) It finishes out with a DPMS quad-rail free-float handguard, a .750-inch diameter low-profile gas block, and an A2 flash hider. The forged 7075-T6 A3 upper receiver is built to mil-spec and hard-coat anodized black, and the bolt is mil-spec shot-peened Carpenter 158 steel with a staked, grade-8 gas key and a parkerized-outside, chrome-lined-inside carrier. All of it is made in the USA to mil-spec manufacturer standards.

Frequently Asked Questions

Is this upper regulated like a short-barreled rifle? No. This is a bare upper receiver group sold without a lower receiver. Barrel length only becomes an NFA/SBR consideration once the upper is mated to a shouldered rifle-configured lower; paired with a pistol lower or braced pistol build, different rules may apply. Confirm your specific lower configuration meets current ATF rules before assembly.

What gas system does this upper use? It uses a pistol-length gas system, sized to run reliably with the 7.5-inch barrel.

What is included on this upper? It ships complete with the barreled upper receiver, quad-rail handguard, low-profile gas block, A2 flash hider, and bolt carrier group.
