Alex Pro Firearms 5.56 Pistol 2.0 10.5 Ranger Fx Mlok

The Alex Pro Firearms 5.56 Pistol 2.0 is a semi-auto AR pistol built for shooters who want a compact, maneuverable platform without compromise on features or build quality. At 10.5 inches, the barrel strikes a balance between velocity and handling—ideal for home defense, vehicle storage, or close-quarters shooting. This 5.56 NATO pistol combines a quality billet receiver set with thoughtful component selection, making it a solid choice for both experienced builders and shooters transitioning to the AR pistol format.

The heart of this build is a 4150CM nitride-coated barrel with a 1:7 twist rate, paired with a .750 carbine-length gas system and APF's adjustable gas block. That tuning flexibility lets you dial in reliability with whatever ammunition and suppressor setup you run. The diamond-honed, nitride M16 bolt carrier group delivers smooth, reliable cycling, while the APF 4.5 lb. drop-in trigger keeps the action predictable and clean without the fuss of a full trigger job.

Ergonomics matter in a compact platform, and APF didn't skimp here. The included Magpul MOE grip and SBA3 pistol brace give you a solid firing platform with wrist support. The 9-inch M-Lok handguard—in the distinctive Ranger FX Cerakote finish—offers mounting flexibility for lights, lasers, or vertical grips, while ambidextrous controls ensure you can run this gun left or right-handed. The billet aluminum receiver set is finished in durable Cerakote, ready to hold up to hard use in the field or at the range.

If you're building or upgrading an AR pistol battery, the 5.56 Pistol 2.0 delivers a no-nonsense platform with room to customize. No iron sights are included, leaving you free to spec your own optic or cowitness setup based on your mission.

Frequently Asked Questions

Can I mount an optic or red dot on this 5.56 pistol?

The billet aluminum receiver is drilled and tapped for a Picatinny rail, and the 9" M-Lok handguard gives you flexible mounting options. You'll need to source your own optic mounting solution based on your sight picture preference—whether that's a micro red dot, prism scope, or laser. The gun ships without iron sights or optic mounts, so you have complete freedom to set it up for your mission.

What's the gas system setup, and can I adjust it for suppressed fire or different ammo?

The .750 carbine-length gas system is paired with an APF adjustable gas block, which means you can tune the system to run smoothly with whatever ammunition or suppressor configuration you choose. This flexibility is a real advantage in a pistol platform where gas tube length and port location can affect reliability and shooting experience.

Is this 5.56 pistol legal to own?

Federal law permits the sale of short-barreled rifles and AR pistols with a brace rather than a traditional stock. However, laws vary by state and locality. It's your responsibility to verify compliance with all applicable federal, state, and local laws before purchase. We recommend consulting local law enforcement or a qualified attorney if you have questions about legal compliance in your area.
