Kel-tec SU16 Carbine A Model .223 Rem/5.56mm AR-15 Rifle - SU-16CA

The Kel-Tec SU16 Carbine A Model is a compact, folding .223 Rem/5.56mm rifle that blends AR-15 platform familiarity with a clever hybrid design. Built on a 16-inch chrome-lined barrel with 1/2-28 threads, the SU16CA combines the field-proven receiver and controls of the SU-16C with the collapsible stock design of the SU-16A model. This is a rifle engineered for hunters, sport shooters, and owners in states with restrictive firearm laws—the folding stock mechanism disables the firing pin when collapsed, making the SU16CA legal to own in most jurisdictions with assault weapons bans.

The real appeal here is versatility without compromise. You get a genuine .223/5.56 carbine with a chrome-lined bore for reliability and durability, paired with the ability to fold the stock flat for transport, storage, or throwdown bags. The magazine storage system is integral to the stock itself, and you'll receive two 10-round magazines that tuck away inside. Parkerized parts protect against corrosion, and the 16-inch barrel is threaded for sound suppressors or other muzzle devices if local law allows. Whether you're zeroing at the range, hunting varmints, or building a truck gun that fits tight spaces, the SU16CA delivers without the bulk.

Kel-Tec's track record with the SU-16 platform is solid—these rifles run hard and run simple. The SU16CA's hybrid approach means you're not sacrificing ergonomics or controls to get compactness. It shoulders and handles like a proper carbine, folds like a takedown rifle, and operates on the same manual of arms shooters already know.

Frequently Asked Questions

Can I use this in a state with an assault weapons ban?

The SU16CA is specifically designed to comply with most state assault weapons restrictions. The folding stock mechanism prevents the rifle from firing when folded, allowing it to be legally owned in states that have such bans. Always check your local and state laws before purchase.

What magazines come with the SU16CA?

The rifle ships with two 10-round magazines that store inside the collapsible stock itself, keeping them accessible but secure.

Can I attach a suppressor or other muzzle device?

Yes, the 16-inch barrel is threaded 1/2-28, which is standard for .223/5.56 suppressors, flash hiders, and muzzle brakes. Check your local laws regarding suppressor and muzzle device legality.

How does the folding stock work, and does it affect reliability?

The SU16CA's stock collapses for compact storage and transport. When folded, the firing mechanism is automatically disabled, so the rifle cannot fire. This is a safety feature and a legal requirement under the ban-compliant design. When unfolded and shouldered normally, it operates like any other .223 carbine.
