Description
There is something grin-inducing about an AR this small. The DPMS DP-15 Kitty Kat takes the platform everyone already knows and shrinks it down around a 7.5-inch heavy-profile barrel chambered in 5.56 NATO, giving you a pistol that handles like a flashlight but hits like a carbine. The chrome moly vanadium barrel wears an M4 extension, a pistol-length gas system, and a classic A2 flash hider on standard 1/2×28 threads, so swapping muzzle devices down the road takes about two minutes.
Why the Kitty Kat Punches Above Its Size
The upper and lower receivers are forged 7075-T6 aluminum with a hardcoat anodized finish, the same recipe you would expect on a full-size duty rifle. Up top, the flat receiver rail flows into a DPMS free-float quad rail, so a red dot, light, laser, and vertical grip all have a home without any adapter gymnastics. A low-profile gas block keeps everything tucked under the handguard, leaving you a clean, uninterrupted sight line for whatever optic you bolt on. Out back, a mil-spec buffer tube carries the DPMS adjustable CAR-style brace, and a familiar A2-style grip and single-stage mil-spec trigger round out the controls.
Where the DP-15 Kitty Kat Earns Its Keep
This format shines anywhere space is tight. It rides well in a backpack or truck bag, makes an easy-handling trainer for working close-range drills, and turns a routine range day into the session everyone wants a turn at. The pistol-length gas system keeps the short barrel cycling reliably with quality 5.56 and .223 loads, and the included 30-round DPMS aluminum magazine means you are ready to shoot the day it comes home. Muzzle blast from a 7.5-inch barrel is part of the experience, so bring good ear protection and enjoy the fireball.
DPMS has been building AR-pattern guns since the 1980s, and the Kitty Kat name has been around long enough to earn a bit of a cult following. This version keeps that character while adding the modern rail space people expect. Small gun, big personality.

Frequently Asked Questions
Does the DPMS Kitty Kat come with sights?
This version uses a low-profile gas block under the free-float quad rail, so plan on adding your own sighting solution. The full-length top rail accepts red dots, holographic sights, or flip-up backup irons without any extra hardware. Most owners drop a compact red dot on it and call it a day.
Will 5.56 cycle reliably out of a 7.5 inch barrel?
Yes, the Kitty Kat runs a pistol-length gas system tuned for the short barrel, and the M4 extension and mil-spec bolt carrier group keep things running the way an AR should. Stick with quality factory 5.56 or .223 ammo, especially during break-in. Like any short-barreled 5.56, it is loud and produces noticeable muzzle flash, which is half the fun.
Can I swap the A2 flash hider on the DP-15 Kitty Kat?
Absolutely. The barrel is threaded 1/2×28, which is the standard pattern for 5.56 AR muzzle devices. That opens the door to linear compensators, brakes, or suppressor mounts, and a linear comp is a popular pick on 7.5 inch builds since it sends blast and noise forward.
What accessories fit on the Kitty Kat's handguard?
The DPMS free-float quad rail gives you Picatinny real estate on all four sides, so lights, lasers, hand stops, and sling mounts attach directly. Because the rail is free-floated, hanging accessories off it will not put pressure on the barrel. It is a straightforward setup with no proprietary mounting systems to fuss with.
