Description
The Andro Corp Industries ACI 5568CB CQB is a compact 5.56 NATO AR pistol designed for close-quarters work, home defense duty, or life as a grab-and-go truck gun. With an 8-inch barrel and overall short footprint, it handles fast and stays out of your way in tight spots where a full-length rifle just gets clumsy.
The heart of this one is a quality build. It runs an 8-inch 4150 CMV barrel with a 1/7 twist and 1/2×28 threaded muzzle, which stabilizes everything from common 55-grain loads up through heavier 77-grain match bullets. Andro Corp is well known for sourcing Ballistic Advantage barrels, the same outfit that supplies barrels found on AR builds costing a good bit more, so you're getting real accuracy potential here. The pistol-length gas system with a low-profile gas block keeps cycling smooth, and the full-auto-rated M16 bolt carrier group adds a little extra mass for reliable extraction and a softer recoil impulse.
Up top you get a 7075-T6 forged upper with T-markings and a 7-inch free-float M-LOK handguard, which gives you plenty of real estate to add a light, a vertical grip, or a hand stop. The 7075 forged lower is Type 3 hard coat anodized and comes with a mil-spec lower parts kit and a standard safety selector. The whole gun feeds from standard AR-15 magazines, so magazines and accessories you already own will drop right in.
Out of the box it comes equipped with an SB Tactical SBA3 adjustable stabilizing brace and one 30-round magazine. An optic is not included, which is fine since most folks have a red dot in mind anyway.
This is a strong pick for the shooter who wants a maneuverable, American-made 5.56 platform that runs reliably and leaves room to grow. Owners consistently point to its solid fit, dependable cycling even with mixed ammo, and the kind of build quality you'd expect to pay more for.

Frequently Asked Questions
What's included with the ACI 5568CB?
It comes with the SB Tactical SBA3 adjustable stabilizing brace and one 30-round magazine. An optic is not included, so you'll want to add your preferred red dot or sights. The M-LOK handguard gives you space for a light or grip as well.
Will it stabilize heavier match ammo?
Yes. The 1/7 twist barrel handles common 55-grain loads and stabilizes heavier projectiles up to about 77 grains, which is the range a lot of shooters reach for in 5.56. That makes it flexible whether you're running cheap range ammo or stepping up to match-grade loads.
Is this a reliable platform with mixed ammo?
It's built around a full-auto-rated M16 bolt carrier group and a tuned pistol-length gas system, which together help it cycle consistently. Owners regularly report it runs everything from quality ammo to budget steel-case without choking. Short-barrel ARs can be finicky, but this one has a reputation for being dependable.
Who is this pistol best suited for?
It's a great fit for home defense, a compact truck gun, or anyone wanting a maneuverable 5.56 in tight quarters. The 8-inch barrel keeps it short and easy to handle indoors or from a vehicle. It's also a solid first AR pistol given the build quality and standard AR-15 parts compatibility.
Does it use standard AR-15 magazines?
It does. The lower feeds from any standard AR-15 magazine, so anything you already own will work. That also makes finding spare mags simple and inexpensive.
