Dpms Firearms Kitty Cat 300Blk 7.5 A4 Quad Rail Car

The DPMS Kitty Cat 300 Blackout pistol is a purpose-built AR pistol chambered for the hard-hitting 300 AAC Blackout cartridge with a compact 7.5-inch barrel. Built on a forged 7075-T6 aluminum lower and MIL-SPEC upper receiver, this short-barreled rifle-configured pistol delivers the ballistic authority of 300 Blackout in a maneuverable package ideal for close-quarters hunting, home defense, and tactical applications. The heavy barrel profile and carbine-length gas system are optimized for reliable cycling with both supersonic and subsonic ammunition—a key advantage of the 300 Blackout platform.

The Kitty Cat is equipped with a DPMS quad-rail free-float handguard that keeps the barrel consistent under load and provides ample real estate for mounting optics, lights, lasers, or other modern accessories. The 1:8 twist rate barrel is a deliberate choice for 300 Blackout, handling the wide range of bullet weights hunters and shooters favor with this cartridge. A low-profile .750-diameter gas block and M4-pattern barrel extension ensure smooth operation, while the mil-spec phosphate-finished barrel handles hard use and variable conditions. An A2-style flash hider tops off the muzzle.

The internals meet military specifications throughout: shot-peened Carpenter 158 steel bolt, parkerized carrier with chrome-lined bore, and grade 8 gas key staked for reliability. The lower features a mil-spec single-stage fire control group and comes dressed with a DPMS adjustable CAR brace and 6-position buffer tube, giving you flexibility to tune ergonomics to your body and shooting style. One 30-round aluminum magazine is included. The hard-coat anodized finish on both receivers resists wear and corrosion in the field.

Frequently Asked Questions

What is the 300 Blackout cartridge best used for?

The 300 AAC Blackout is a versatile short-to-medium-range cartridge designed to perform well with both standard supersonic loads (around 2,200 fps) and subsonic ammunition (below 1,125 fps). This makes it popular for hunting medium game, tactical training, suppressed shooting, and situations where lower recoil and noise are advantages. It's also a common choice for pistol-caliber builds and short-barreled platforms like the Kitty Cat.

Can I use a suppressor with this pistol?

The barrel is threaded with a 5/8 x 24 muzzle pattern, a standard thread size that accepts suppressors designed for this mounting. The 300 Blackout's reputation for subsonic capability makes suppressed shooting a popular application, though you'll need to verify any suppressor you choose is compatible with pistol-length barrels and .300-caliber projectiles.

What's included with the Kitty Cat 300 Blackout?

The pistol ships with one 30-round DPMS aluminum magazine. All other components—receiver, barrel, handguard, bolt carrier, brace, buffer tube—are factory-assembled and ready to shoot.

Is the quad-rail handguard suitable for optics and accessories?

Yes. The DPMS quad-rail free-float handguard provides four rails for mounting optics, magnifiers, lights, lasers, vertical foregrips, or other Picatinny-compatible gear. The free-float design isolates the rail from barrel harmonics, which helps maintain consistency for optic reticle alignment and shot placement.
