Alex Pro Firearms 5.56 Nato Fury 16 Tactical Mermaid Mlok
The Alex Pro Firearms 5.56 NATO Fury 16 is a mid-length tactical rifle built for shooters who want a compact, duty-ready platform without compromise. This semi-automatic AR is chambered in 5.56 NATO and features a 16-inch 4150CM nitride-coated barrel with a 1:7 twist rate, making it equally at home on the range, in a 3-gun competition, or deployed for home defense. The forged receiver and diamond-honed nitride bolt carrier group provide the durability you'd expect from a serious build, while the APF adjustable gas block lets you tune performance for your specific ammunition and suppressor setup.
Where the Fury shines is in its thoughtful control layout and ergonomics. The APF 4.5 lb. drop-in trigger delivers a clean, predictable break without gunsmithing, and the 15-inch M-Lok handguard gives you plenty of real estate to mount lights, lasers, or slings exactly where you want them. The Magpul MOE PR stock and MOE grip are field-proven, comfortable, and reliable—no frills, all function. Built on a .750 mid-length gas system, this rifle balances recoil management with parts longevity, and the nitride finish across barrel and BCG resists corrosion without the weight penalty of more exotic coatings.
Finished in Mermaid Tactical Cerakote, the Fury stands out without sacrificing durability or function. This is a rifle for shooters who know what they want: a no-nonsense 5.56 platform that runs, handles well, and doesn't require a gunsmith visit before you hit the range. Right-hand only.

Frequently Asked Questions
What does the adjustable gas block do?
The APF adjustable gas block lets you fine-tune the amount of gas cycling through the bolt carrier group. This is especially useful if you run a suppressor, use different ammunition types, or want to reduce recoil and muzzle rise. You can dial it in to your exact setup rather than relying on a fixed gas port.
Is this rifle good for 3-gun or competition shooting?
Yes. The 16-inch barrel, 4.5 lb. trigger, adjustable gas block, and M-Lok handguard are all features that appeal to competitive shooters. The mid-length gas system is known for reliability and shootability, and the compact profile is easier to manage in transitions and from barriers than a longer rifle.
Does it come with sights?
No. The Fury ships without front or rear iron sights. The top of the receiver is rail-equipped, so you can mount any optic or combination of sights that fits your mission.
Is the trigger user-replaceable?
Yes. The APF 4.5 lb. drop-in trigger is designed to swap easily without gunsmithing, though if you decide to use a different trigger later, that's straightforward too.
