Dpms Firearms Kitty Cat 5.56 7.5 A4 Quad Rail Car Brace

The DPMS Kitty Cat 5.56 is a compact, purpose-built AR pistol that brings serious capability to a short-barreled platform. Built on a forged 7075-T6 lower and mil-spec upper receiver, this 7.5-inch 5.56 NATO carbine delivers the modularity and reliability AR shooters demand in a tight, maneuverable package. Whether you're building a truck gun, home-defense rig, or specialized training setup, the Kitty Cat's proven component selection and domestic manufacturing give you a solid foundation without the guesswork.

The heart of this build is a chrome-moly vanadium barrel with a 1:7 twist rate, phosphate-finished for corrosion resistance and paired with a carbine-length gas system. The free-floating quad rail handguard gives you the flexibility to mount optics, lights, or other accessories exactly where you need them, while the low-profile gas block keeps the upper rail clean and unobstructed. An A2-style flash hider comes installed and ready to run.

DPMS doesn't cut corners on internal hardware: the bolt is mil-spec shot-peened Carpenter 158 steel with a full-auto carrier profile, parkerized outside and chrome-lined inside for longevity. The gas key is staked per spec with grade 8 fasteners—the mark of a firearm built to last. The fire control group is a mil-spec single-stage trigger assembly, predictable and reliable out of the box.

The pistol brace is DPMS's adjustable CAR design, mounted on a 6-position buffer tube so you can dial in the fit you want. Comes ready to shoot with one 30-round aluminum magazine. If you need a short, handy 5.56 that respects the details, this is worth a close look.

Frequently Asked Questions

Is this an AR pistol or a short-barreled rifle?

The Kitty Cat comes configured as an AR pistol with a pistol brace rather than a traditional stock. Check your local and federal regulations regarding AR pistols in your area before purchase.

Can I use standard AR-15 magazines and ammunition?

Yes. The 5.56 NATO chamber accepts standard 5.56 and .223 Remington ammunition, and the pistol comes with one 30-round DPMS aluminum magazine. Any standard AR-15 magazine will work.

What comes in the box?

The Kitty Cat ships with one 30-round aluminum magazine. You'll need to source ammunition, a sling, and any optics or light rails separately.

Can I add or swap the pistol brace?

Yes. The adjustable CAR brace is mounted on a standard mil-spec buffer tube, so you can replace it with other compatible braces if needed.
