Description
The DPMS DP-15 Classic complete lower is the shortcut a lot of folks are looking for when they want to build a compact AR pistol without chasing down parts one at a time. It arrives fully assembled on a forged 7075-T6 aluminum receiver marked MULTI, so it plays nice with whatever mil-spec upper you throw at it, whether that's 5.56, .300 Blackout, or something else in the AR-15 family. The whole thing wears a hardcoat anodized finish that shrugs off scuffs and holds up to regular handling.
What Sets the DP-15 Classic Lower Apart
The standout here is the DPMS CAR-15 blade brace. It's an injection-molded polymer piece with a retro look that harks back to the old carbine profile, and it rides on a mil-spec diameter 7075-T6 buffer tube with six adjustment positions. That lets you dial the length in for your reach and shooting stance. Because the buffer tube is standard mil-spec, swapping the brace down the road for a different stock or brace setup is a simple job if your build ever changes direction.
Trigger and Furniture on the DPMS DP-15
Inside you get a DPMS Retro single-stage fire control group with a black oxide finish, which gives you a clean, familiar pull right out of the box. The grip is a DPMS A2-style unit in black, the classic AR angle that most people already know and shoot well with. Everything is factory-installed, so there's no fiddling with detent pins, springs, or springs launching across the garage.
Building on the DP-15 Classic
Think of this as your foundation. Pair it with a complete mil-spec upper and bolt carrier group and you've got a functioning firearm without sweating the small parts. It's a favorite starting point for a lightweight, maneuverable build meant for close-quarters handling and quick range work. If you like the idea of a compact platform with a nod to old-school carbine styling, this lower gets you most of the way there in one box.

Frequently Asked Questions
What caliber does the DPMS DP-15 Classic lower work with?
The receiver is marked MULTI, meaning it's not tied to a single caliber. It will pair with any standard mil-spec AR-15 upper, so common chamberings like 5.56 NATO, .223, and .300 Blackout are all on the table. Your final caliber comes down to whichever upper and bolt carrier group you mate to it.
Is the DP-15 complete lower ready to shoot on its own?
No, a lower by itself is only part of the equation. You'll need to add a complete upper receiver with a bolt carrier group and charging handle to have a functioning firearm. The upside is that all the lower's internal parts, buffer tube, brace, and grip come already installed, so the assembly work is done for you.
Can I swap the CAR-15 blade brace for a different brace or stock later?
Yes. The brace rides on a mil-spec diameter buffer tube, which is the standard size for AR-15 stocks and braces. That means most aftermarket options will slide right on if you decide to change the setup down the road.
What is the DPMS DP-15 known as, and why do people call it the Kitty Kat?
Kitty Kat is DPMS's nickname for this compact platform, and you'll see the two names used interchangeably across listings. The name reflects the small, nimble nature of the build. This particular item is the complete lower portion of that platform rather than a full pistol.
