Description
The DPMS Panther Arms CAR-15 Complete Lower takes most of the guesswork out of building an AR-15. It ships assembled with the fire control group, buffer tube, stock, and grip already in place, so you skip the fiddly detent springs and roll pins that trip up a lot of first-time builders. The receiver is forged from 7075-T6 aluminum and wears a hardcoat anodized finish, the same tough coating you'll find on quality mil-spec receivers. It's marked MULTI for caliber, so it pairs with any standard AR-15 upper in the usual chamberings like 5.56 NATO, .223, and the pile of other cartridges built on the platform.
What You Get With the DPMS CAR-15 Lower
The buffer tube is a mil-spec diameter 7075-T6 unit with six adjustment positions, which lets you set length of pull to fit your build, your gear, and whoever else might shoulder the rifle. Riding on it is the DPMS Retro CAR-15 stock, a lightweight Fiberlite buttstock that leans into that classic carbine profile without adding bulk. The pistol grip is a DPMS Retro A2 style, and the whole package keeps a clean, throwback silhouette that fits retro builds beautifully while still working fine on a modern setup.
Why the CAR-15 Complete Lower Makes Building Easy
The fire control group is a DPMS Retro single-stage assembly finished in black oxide. Single-stage triggers are the workhorse of the AR world, and this one gives you a straightforward, predictable pull that's right at home for range days, plinking, and general-purpose shooting. Since the internals are already installed, you're really just adding an upper to have a functional carbine.
DPMS has been building AR-pattern rifles and parts out of Minnesota for decades, and their receivers have a long reputation for solid fit and value. If you want a fast path to a running rifle or a period-correct retro build without sourcing a dozen small parts, this complete lower is a smart starting point.

Frequently Asked Questions
What upper works with the DPMS CAR-15 complete lower?
It accepts any standard mil-spec AR-15 upper receiver, since it's built to AR-15 dimensions and marked MULTI for caliber. That means you can run common chamberings like 5.56 NATO and .223 Rem, along with most other cartridges built on the AR-15 platform. Just make sure your upper matches the caliber of the barrel and bolt you're running.
Is the CAR-15 lower ready to shoot or do I need to install parts?
The lower comes assembled with the fire control group, buffer tube, stock, and grip already installed. You won't need to fight with detents, springs, or roll pins to finish it. All you have to do is add a complete upper receiver to have a functional carbine.
What kind of trigger comes in this DPMS complete lower?
It uses a DPMS Retro single-stage fire control group finished in black oxide. A single-stage trigger gives you a consistent, predictable pull that's well suited to range work and general shooting. If you ever want something lighter or crisper down the road, it can be swapped for an aftermarket trigger later.
Does the buffer tube adjust, and what stock is on it?
Yes, the mil-spec diameter buffer tube has six positions so you can dial in length of pull. It comes fitted with the DPMS Retro CAR-15 Fiberlite stock, a lightweight adjustable buttstock with a classic carbine look. It's a good match for retro-style builds while still functioning on a modern setup.
