Description
The CA-15 Pistol from Combat Armory takes everything people like about the AR platform and trims it down to a fast-handling, truck-friendly package. At the heart of it is a 10 inch 4140 chrome moly vanadium barrel with a Melonite finish, an M4 profile, and a 1:7 twist that stabilizes the heavier 5.56 loads most folks run through short barrels. The carbine-length gas system paired with a .750 low profile gas block keeps the action cycling smoothly, and the 1/2×28 threaded muzzle wears a classic A2 flash hider that you can swap for the muzzle device of your choice.
Billet Receivers on the CA-15, Not the Usual Forged Fare
Both the upper and lower are machined from billet 7075-T6 aluminum and finished in Type III hard coat anodizing, which is a step up in looks and rigidity from the standard forged receivers you see at this end of the market. You still get the familiar M4-style layout with a forward assist, dust cover, and mil-spec charging handle, plus an ambidextrous-style safety that lefties will appreciate. The fire control group is mil-spec, so upgrading to a drop-in trigger down the road is as simple as it gets.
A 10 Inch M-LOK Handguard Built for Accessories
The free float handguard runs the full 10 inches of the barrel and combines a continuous Picatinny top rail with M-LOK slots along the sides and bottom. That gives you an uninterrupted platform for optics and backup sights up top, with plenty of real estate for lights, lasers, and hand stops wherever you want them. Because the handguard is free floated, none of that gear puts pressure on the barrel, which helps keep your groups consistent.
Why the Combat Armory CA-15 Pistol Makes Sense
This configuration ships with a single 10-round magazine and a standard pistol buffer tube, giving you a clean starting point to set the gun up your way. Whether you are after a compact range companion, a home defense setup, or a base for a bigger build, the CA-15 delivers mil-spec compatibility and billet construction without the boutique price tag attitude. Pair it with a red dot and a light and it is ready to work.

Frequently Asked Questions
Does the Combat Armory CA-15 Pistol come with a brace or stock?
No, this model ships with a standard pistol buffer tube and no brace attached. That keeps the package simple and lets you configure the rear end of the gun however you prefer. The tube accepts common pistol-length accessories designed for AR-style builds.
Can I shoot .223 Remington through the CA-15 in addition to 5.56?
Yes. The barrel is chambered in 5.56 NATO, and a 5.56 chamber safely handles both 5.56 NATO and .223 Remington ammunition. The 1:7 twist rate also does a nice job stabilizing heavier bullets, which tend to perform better out of a 10 inch barrel.
Will standard AR-15 magazines and parts work with this pistol?
They will. The CA-15 is built around mil-spec components, so it accepts standard AR-15 pattern magazines and the huge universe of aftermarket triggers, grips, charging handles, and muzzle devices. It includes one 10-round magazine in the box, and swapping parts later is straightforward.
Does the Combat Armory CA-15 have sights or an optic included?
No sights or optics come installed. The upper receiver and 10 inch handguard share a continuous Picatinny top rail, so mounting a red dot, low power scope, or a set of flip-up iron sights takes just a few minutes. Most owners pair a short-barreled 5.56 like this with a red dot for quick target acquisition.
