Availability: In Stock
A quality replacement or spare barrel for your AR platform rifle, the CMC Triggers 5.56 NATO 16" barrel in black gives you options when you need them. Whether you're building a new upper, swapping calibers, or keeping a backup ready, a dedicated barrel is a straightforward way to expand what your AR can do without buying an entirely new rifle. At 16 inches, this barrel offers a practical balance of velocity and handling—compact enough for tactical or home-defense setups, yet long enough to wring good performance from 5.56 NATO ammunition.
CMC Triggers is known for precision components, and this barrel follows that standard. A properly fitted barrel is the foundation of accuracy and reliability in any AR build, so sourcing one from a reputable maker matters. This one comes finished in black, which means it'll integrate cleanly with most modern furniture and coatings.
Swapping an AR barrel is straightforward work if you have basic gunsmithing knowledge or a armorer's wrench and upper vice block—no permanent modifications to your rifle needed. This makes a spare barrel one of the smartest investments for shooters who want flexibility without the expense of a second complete upper receiver.
| Caliber | 5.56 NATO |
| Barrel Length | 16" |
| Finish | Black |
| Manufacturer | CMC Triggers |
This is a 5.56 NATO barrel sized for standard AR-pattern uppers. Fit depends on your specific upper receiver—compatibility is determined by the barrel extension profile and bore diameter. If you're unsure, consult your upper's documentation or contact us.
At 16 inches, this 5.56 NATO barrel can certainly be used for hunting, though performance and effective range will vary depending on your game and local regulations. Many hunters prefer this caliber and barrel length for varmint work and lighter game.
You'll need an armorer's wrench sized for your barrel nut and an upper receiver vice block to safely hold the upper during installation. This is work many shooters handle themselves, or you can have a qualified gunsmith install it.
A 16" barrel exceeds the legal length for AR pistols in most jurisdictions. Check your local and federal laws before building any firearm configuration.
