ATI ALPHA MAXX RIA FDE Rifle 5.56mm 60rd Magazine 16'' Barrel 13'' MLOK Handguard

The ATI ALPHA MAXX RIA FDE rifle in 5.56mm is a modern sporting rifle built for shooters who want a practical, modular platform without the premium price tag. With its 16-inch heavy barrel, full M-LOK handguard, and flat dark earth finish, this is a no-nonsense rifle equally at home on the range, in a defensive role, or running carbine drills. The included 60-round magazine and fixed rear sight setup give you a complete package ready to shoot out of the box.

The 13-inch M-LOK handguard gives you plenty of real estate to mount lights, lasers, grips, or other accessories without the complexity of full-length rails. M-LOK slots are positioned for practical mounting, and the modular design means you can configure the rifle to your specific needs. The heavy 16-inch barrel strikes a balance—enough velocity for 5.56 ballistics out to typical rifle distances, with a barrel profile that resists heat buildup during sustained fire.

Flat dark earth has become the go-to finish for modern rifles, and for good reason: it's practical in most environments and doesn't screech "tactical" while still looking purpose-built. Whether you're building a home defense rifle, a range workhorse, or a general-purpose 5.56 shooter, the ALPHA MAXX RIA gives you a solid foundation and the modularity to make it your own.

Frequently Asked Questions

What's included with the ATI ALPHA MAXX RIA?

The rifle ships with a 60-round magazine and fixed rear sight, so you have the essentials to get to the range immediately.

Can I mount a scope or red dot on this rifle?

Yes. The rifle features M-LOK mounting capability on the 13-inch handguard, and the fixed rear sight can accommodate optic mounting options depending on your setup preferences.

What's the advantage of a 16-inch barrel in 5.56?

A 16-inch barrel is the most common length in modern carbines because it provides good velocity and energy for 5.56 ballistics while keeping the overall rifle length manageable for training, home defense, and practical shooting disciplines.

Is the M-LOK handguard compatible with standard 5.56 accessories?

M-LOK is a standardized mounting system, so any M-LOK-compatible accessory—lights, vertical grips, bipods, cable management—will work with the 13-inch handguard on this rifle.
