Every so often, a gun comes out that just makes you go “dang.” That aptly sums up the Springfield Armory Kuna. This large-format PDW pistol has caught the attention of the masses, with its roller-delayed action, flat trigger and ambidextrous controls on something that looks suspiciously like a MP5. It has, in fact, been selling well at a time when many brands have been suffering.
However, despite its many nice features, this braced, or unbraced, pistol just begs for customization. How could anyone have such a PDW without attaching an optic, light, laser, suppressor, or all the above? It doesn’t really matter what shooters attach to the Kuna. It is even a great gun for a stock, especially with the elimination of the tax stamp on short-barreled rifles. Here’s some hardware to consider for the Springfield Armory Kuna.
The Springfield Kuna is a pistol. It’s a large-frame pistol but it is a pistol under the law. That means that adding a stock to this gun requires filing ATF forms 1 and 4 and waiting for approval. It might be better to just add a brace instead. However, since it is now a $0 Tax Stamp, a SBR might be the better option in the long run. It is now just some paperwork with a wait. That’s a choice that shooters have to make for themselves.

Those who are interested in creating a SBR with the Springfield Armory Kuna should consider the Magpul UCS. This versatile stock is built for receivers with an M1913 Picatinny mounting interface, such as the Kuna.
The UCS comes with a reversible hinge for left and right folding configurations. It ships with two cheek risers — .5 and .75 inches. Adding in the 1/2-slot height adjustment, shooters have quite a bit of adjustment of head placement. This allows for an optimal sight picture, whether using iron sights or optics.
Via a button, the UCS has six positions providing 3 inches of length-of-pull adjustment. It also comes with a reversible, anti-rotation QD socket for sling attachments, as well as the MOE SL Enhanced Rubber Butt-Pad. Being easy to attach and use makes the Magpul UCS and excellent option to turn the Kuna into an SBR.

While the Kuna comes with an optional Strike Industries FSA brace, it only folds to the left. Some folks might want the option of folding either way. For that, the FSA Dual Folder works well.
It uses an intuitive folding mechanism to go both ways, providing a positive lock to stay in place when in use. Deployment is quick and easy with an upward pull on the bar near the hinge. It even has a three-degree tilt angle to prevent interference with the ejection port when folded to the right, as well as an ambidextrous QD point on the rear of the stabilizer for attaching a sling.
Constructed with a steel hinge and 6061-T6 Aluminum base, adapter and strut, the Strike Industries FSA Dual Folder is light, tough and an excellent option for those who don’t want to convert their Springfield Armory Kuna.
The Kuna comes with two sets of iron sights. One is low to the rail like pistol sights, while the other flip up for use with a brace. They’re actually pretty good and work well. However, most folks will prefer attaching an optic, such as a red dot, to the rail, particularly if using it braced or with a stock.

The Leupold Deltapoint Pro remains one of the most trusted red dots on the market. A lot of this is due to its wide field of view, clear glass, and rugged aluminum‑and‑steel construction. These qualities make target acquisition fast and intuitive. Its top‑loading battery and motion‑activated system add practical reliability for defensive or duty use.
It can also be because Leupold is known for quality. The Deltapoint Pro comes waterproof, shockproof and fog proof. Its 2.5 MOA dot provides for precise shot placement, and its wide field of view lets users see everything, with good contrast in low-light situations. It even comes with Motion Sensor Technology, which turns the unit off to save battery power but awakens with movement.

The Athlon Midas Flare is a compact, rugged prism optic built for fast, clear target acquisition, making it excellent for braced pistols and SBRs. It uses a prism-based design for a crisp image in a shorter housing, while its etched reticle stays visible even without illumination.
The optic is nitrogen‑purged, waterproof, fog proof and shockproof. This gives it reliability on high‑recoil or rapid‑handling platforms. Multiple red/green (depending on model) brightness levels and fully multi‑coated lenses help maintain visibility in any environment. Whether in 1x for true close‑quarters speed or 3x for added reach, the Midas Flare offers durability and clarity without adding bulk.
Darkness can be unnerving, which is why it is a good idea to attach a light to a gun, especially a home-defense gun. Of course, the Kuna comes with M-LOK attachment points, so users will need to find a light that uses M-LOK or use an adaptor. Some gun lights even come with an included laser, providing a two-for-one in accessories. There are, of course, lasers that don’t include lights.

The Olight PL X stands out for its dual‑beam system, offering a 1,200‑lumen flood for room‑filling illumination and a focused spotlight for long‑range identification. This gives shooters close‑ and far‑range capability without switching modes mid‑use.
Its USB‑C rechargeable battery, ambidextrous controls and universal quick‑release rail mount make it user‑friendly and easy to run on a wide variety of pistols. The PL X is also built tough with an aluminum body, IPX7 waterproofing and 1.5‑meter drop resistance. It offers durability well‑suited for training or defensive carry.
For shooters wanting maximum versatility in a compact, competitively priced light, the PL X delivers performance that punches above its weight.

The Crimson Trace CMR‑301 Rail Master is a compact light‑and‑laser combo built for rail‑equipped long guns, as well as braced pistols. It pairs a 1,000‑lumen white light with a powerful green laser, giving shooters strong illumination and fast visual indexing in both bright and low‑light conditions.
Its aluminum housing, Picatinny and M‑LOK mounting options and user‑programmable modes (light only, laser only or both) make it adaptable to a wide range of setups. The unit runs on a rechargeable battery and can be activated via push‑button or remote pressure pad. This offers flexible control depending on grip preference.
For shooters who want to conserve rail space while gaining illumination and a visible aiming option, the CMR‑301 delivers a robust, streamlined solution that fits neatly into modern defensive and tactical rifle builds.

The Holosun LE117‑R is a durable, titanium‑housed Class IIIa red laser aiming device, offering rugged reliability in a compact package. It features a quick‑release Picatinny mount, tactile windage/elevation adjustments and a rear selector switch allowing constant‑on or remote‑switch activation. Powered by a single CR123 battery, it delivers up to 5,000 hours of runtime.
With its IPX8 waterproof rating, precise collimated red laser and streamlined controls, the LE117‑R stands out as a professional‑grade aiming solution without a heavy price tag. Shooters looking for a lightweight but robust aiming tool will find the LE117‑R an appealing, well‑built option.
There are all kinds of accessories for tricking out the Springfield Kuna. I personally attached a Riton Optics 1Tactix ARD 2 and a Banish 46-V2 suppressor to mine that came with the Strike Industries FSA. This gave it a PDW look, while making recoil almost nonexistent. I really liked the Riton’s 2 MOA dot surrounded by a 30 MOA circle for drills, though I sighted it in with just the dot.
While the Banish 46 works well on the Kuna, it is designed for larger calibers. So, I am currently waiting on approval for a Dead Air Silencers RXD910Ti, which is optimized for 9mm. I’m also waiting on an adaptor to come in for attaching a light. It might end up being a light/laser combo for giggles and to keep down weight. I also think I may need to attach a sling.
