Alex Pro Firearms 5.56 Pistol 2.0 10.5 Blk Mlok

The Alex Pro Firearms 5.56 Pistol 2.0 is a purpose-built 5.56 NATO AR pistol that splits the difference between a full-length rifle and a compact PDW—ideal for shooters who need serious firepower in a maneuverable package. Built on a billet receiver set with ambidextrous controls, this 10.5-inch pistol delivers rifle-caliber performance from a handgun-length platform. Whether you're running drills at close quarters, setting up a truck gun, or building a short-range duty setup, the 2.0 combines proven components and thoughtful engineering to give you a reliable, no-compromise performer.

The heart of the build is a 10.5-inch 4150CM barrel with nitride coating and a 1:7 twist rate, paired to a .750 carbine-length gas system and adjustable gas block so you can dial in reliability with any load or configuration. The diamond-honed nitride M16 bolt carrier group is built to specification and pairs with APF's 4.5 lb. drop-in trigger for a predictable break. M-Lok slots along the 9-inch handguard give you real estate for lights, lasers, or vertical grips, while the Magpul MOE grip and SBA3 pistol brace ensure you've got ergonomics and stability locked in. The black Cerakote finish resists wear and corrosion, making this pistol ready for hard use out of the box.

No front or rear sights are included—that's intentional, letting you mount glass, red dots, or irons exactly the way you want them. The compact form factor and semi-auto action make this a legal AR pistol in most jurisdictions, but always verify local and state laws before purchase.

Frequently Asked Questions

What's included, and what do I need to add?

The Alex Pro Firearms 5.56 Pistol 2.0 ships complete and ready to function—no additional lower receiver or serialized parts needed. You'll need to supply an optic or iron sights to aim it; no front or rear sights are included. You'll also want ammunition (5.56 NATO) and, depending on your setup, possibly a light or laser mounted to the M-Lok handguard.

Is this a legal AR pistol?

Yes, it meets the federal definition of an AR pistol: it's a semi-automatic rifle platform configured with a pistol brace instead of a rifle stock, no vertical foregrip, and overall dimensions compliant with federal law. However, state and local laws vary significantly regarding AR pistols, braces, and accessories. Verify all applicable laws in your jurisdiction before purchasing or taking possession.

Will the adjustable gas block help with reliability and reliability?

The APF adjustable gas block lets you tune the amount of gas flowing into the bolt carrier group. This is especially useful in a short 10.5-inch platform where gas dwell can be aggressive; you can dial it down for smoother cycling, reduced recoil, and longer component life, or dial it up if you're using suppressed or underpowered loads.

What kind of rail space do I have for accessories?

The 9-inch APF M-Lok handguard provides M-Lok mounting slots, allowing you to attach lights, lasers, vertical grips, and other modern accessories without traditional Picatinny rail. M-Lok is lighter and cleaner than quad-rail while offering plenty of real estate for the gear you actually need.
