Combat Armory CA15 Slim Pistol 10 Round 5.56 7.5in – Lightweight Reliable AR

Description

The Combat Armory CA15 Slim Pistol 10 Round version is a compact 5.56 NATO AR-15 pistol with a 7.5-inch barrel and a 7-inch slim free-float M-LOK handguard, shipped with a 10-round magazine instead of the usual 30. It is the lightest, trimmest member of the CA15 pistol family, and the reduced-capacity magazine makes it a practical choice for buyers who prefer or need a 10-round configuration.

Combat Armory CA15 Slim Pistol 10 Round Overview

Combat Armory machines the upper and lower receivers from billet 7075-T6 aluminum and finishes them in Type III hard-coat anodized black. The 4140 chrome-moly vanadium barrel carries a Melonite finish, M4 profile and feed ramps, a 1-in-7 twist and 1/2×28 threads with an A2 flash hider. A pistol-length gas system with a low-profile .750 gas block runs underneath the slim handguard. The lower comes with a bare pistol buffer tube and no brace or stock. Apart from the magazine, it matches the 30-round slim-rail CA15 pistol.

About the 10-Round Magazine

The included 10-round magazine sits shorter below the receiver, which helps when shooting from a bench or prone and makes the pistol easier to store in a case or vehicle safe. Some states limit magazine capacity, so a 10-round configuration can help with compliance, but many of those same states also ban or restrict AR-style pistols outright. A low-capacity magazine alone does not make this firearm legal everywhere. Always check your state and local law before ordering.

Slim Rail Handling

The slim M-LOK handguard has a smaller profile than a full-top-rail design, so the pistol is lighter up front and easier to grip. The receiver flat-top holds your optic, while the handguard slots accept a light, a sling mount or a hand stop. On a 7-inch handguard, a hand stop is especially worthwhile because it keeps your support hand safely behind the muzzle and flash hider during fast shooting.

Short Barrel Considerations

A 7.5-inch barrel produces noticeably less velocity than a carbine barrel, plus a loud report and a large fireball. Wear quality hearing protection, and avoid shooting indoors without it. Suppressors can tame the noise but are NFA items requiring an approved ATF Form 4 and state approval. If you want maximum range and terminal performance, a 16-inch rifle is the better choice; this pistol trades those for compact size and handling.

Braces and Configuration

The pistol is shipped as a pistol with a bare buffer tube. Stabilizing brace regulations have changed more than once in recent years, so confirm current ATF rules and your state laws before installing one. Do not install a shoulder stock or a vertical foregrip: a stock on a sub-16-inch barrel creates a short-barreled rifle under the National Firearms Act, and a vertical grip on a pistol raises its own NFA concerns. Angled grips and hand stops are common, lawful alternatives.

Upkeep and Value

Mil-spec internals keep maintenance and upgrades simple, and the Melonite barrel resists corrosion and wear. Lubricate the bolt carrier group before shooting and favor brass-cased ammunition during break-in. Combat Armory is a newer name with lower resale value than legacy brands, but billet receivers and a free-float handguard at this price make it an attractive option for a compact range or truck gun.

Safe Storage

Store handguns unloaded in a locked safe, lockbox or with a cable lock, and keep ammunition separate when children are in the home. Quick access safes let you keep a defensive handgun secure but available. Teach everyone in the household basic firearm safety rules.

Ordering From MAG5

Choose your local FFL dealer at checkout and we ship directly to them. Once the firearm arrives, your dealer will run the background check and complete the transfer paperwork. Most dealers charge a modest transfer fee, so ask about it before you order.

State Laws and Ownership

AR-15 pistols are handguns under federal rules and are banned or heavily restricted in states such as California, New York, New Jersey, Maryland, Massachusetts, Connecticut, Illinois and Washington, whether or not they have a 10-round magazine. In Pennsylvania, AR pistols are handguns, buyers complete a PICS check, and concealed or vehicle carry requires a License to Carry Firearms. Confirm with your receiving FFL that you can lawfully take delivery before ordering.
