Description
For the U.S. firearms owner seeking a compact, reliable carbine that bridges the gap between a pistol and a rifle, the Arsenal SLR106-55PR offers a practical solution. Chambered in the widely available 5.56 NATO, this factory-built SBR provides familiar ballistics in a highly portable package, making it suitable for home defense, truck gun use, or range training. With its origins in the proven AK platform, this Krink-style pistol delivers consistent performance without the need for a tax stamp or custom build.
What This Product Is and Who It’s For
The Arsenal SLR106-55PR is a factory-manufactured short-barreled rifle (SBR) chambered in 5.56x45mm NATO. It is built on Arsenal’s renowned stamped receiver, featuring an 8.5-inch barrel that keeps the overall length compact while maintaining the ballistic profile of the 5.56 round. This model is intended for shooters who value maneuverability in tight spaces—such as home defense or vehicle storage—without sacrificing the reliability of a traditional AK action. It also appeals to collectors who appreciate the factory-original SBR configuration, as it avoids the complexity and legal hurdles of building a similar firearm from a pistol receiver. Target shooters will find it a capable platform for plinking and close-range drills, while hunters may use it for varmint control or brush hunting where a short barrel is advantageous.

Feature Deep-Dive
The Arsenal SLR106-55PR stands out due to its factory SBR status. Unlike a pistol that requires a tax stamp and Form 1 to convert, this firearm is transferred as a Title II NFA item, meaning the manufacturer has already handled the legal registration. This ensures the firearm is built to exacting specifications from the ground up, with no aftermarket modifications that could compromise reliability. The 8.5-inch barrel is chrome-lined for corrosion resistance and extended service life, a feature that matters for shooters who fire frequently or store their firearm in varied conditions.
The gas system on the SLR106-55PR is tuned specifically for the shorter barrel length. Arsenal uses a proprietary gas port size and piston design to ensure reliable cycling with standard 5.56 ammunition, including lower-pressure loads. This is a common pain point with AK-pattern rifles in 5.56, as many aftermarket barrels require adjustment or break-in. The factory configuration eliminates this guesswork, providing consistent ejection and bolt travel from the first round. The bolt carrier group is machined from a solid forging, with a nitrided finish that reduces friction and wear over thousands of rounds.
The folding stock is another practical feature for U.S. owners. It locks securely when extended and folds to the left side, reducing the overall length to roughly 24 inches for storage or transport. The polymer construction keeps weight down without sacrificing rigidity, and the cheek rest provides a consistent cheek weld for iron sight use. The stock latch is robust and easy to operate with the support hand, making the transition from folded to ready quick. For users who prefer a red dot or magnified optic, the receiver includes an integral side rail that accepts standard AK scope mounts, allowing for easy accessory attachment without drilling or tapping.
Magazine compatibility is a strong point for this model. The SLR106-55PR uses standard 5.56 NATO AK magazines, which are widely available from manufacturers like Arsenal, Circle 10, and KCI. These magazines are steel-reinforced and feature a polymer body that resists cracking. The magazine release is a standard AK lever, and the well is beveled for smooth insertion. While the rifle can also feed from .223 Remington magazines, we recommend using magazines specifically designed for the 5.56 cartridge to ensure reliable feeding with the shorter barrel’s gas system. The bolt hold-open feature is present when the magazine is empty, a convenience often missing on AK-pattern rifles.
The finish on the SLR106-55PR is a durable black phosphated coating that resists rust and wear. The barrel is button-rifled with a 1:7 twist rate, stabilizing both 55-grain and 62-grain projectiles effectively. The muzzle is threaded (commonly 1/2×28) for attaching suppressors or other muzzle devices, though we advise checking local laws regarding NFA items. The handguard is a standard AK-100 series polymer unit with a heat shield, providing a secure grip under rapid fire. Overall, this rifle is built to the same quality standards as Arsenal’s full-size rifles, with attention to headspace, bolt lug engagement, and feed ramp geometry.
Ideal Use Cases
The SLR106-55PR is well-suited for home defense due to its compact size and reliable cycling. The 5.56 NATO round offers effective terminal performance at close range with reduced risk of overpenetration compared to larger calibers. It can serve as a truck gun or ranch rifle for those who need a portable, hard-hitting option that fits in a backpack or behind a seat. For target shooters, it is a capable range gun for drills up to 100 yards, offering the familiar AK manual of arms. It is not intended for concealed carry or competition use, as its size and weight exceed typical handgun parameters, but it can be pressed into service for varmint hunting or property protection in rural settings.
Compatibility Notes
- Ammunition: Functions reliably with 5.56x45mm NATO and .223 Remington ammunition. We recommend using brass-cased, factory-loaded ammunition for best performance. Steel-cased ammunition may work but could increase wear on the extractor and chamber.
- Magazines: Uses standard 5.56 NATO AK magazines. Factory Arsenal Circle 10 magazines provide the best fit and reliability. Magazines from KCI and other reputable brands are compatible but may require minor fitting.
- Holsters: Not applicable; this is a rifle/pistol hybrid and is not designed for holster carry. It may fit in some compact rifle cases or padded bags.
- Accessories: The side rail accepts standard AK scope mounts (e.g., RS Regulate, Midwest Industries). The handguard can be replaced with aftermarket options that fit the AK-100 series pattern. Muzzle devices with 1/2×28 threading are compatible.
- Cleaning & Maintenance: Standard AK cleaning procedures apply. Use a bore brush and solvent for the chrome-lined barrel. Lubricate the gas piston and bolt carrier with a light oil.
Frequently Asked Questions

A: Yes, we ship to licensed FFL dealers in all states where NFA items are legal. This includes most states, but please verify local laws regarding SBR ownership. We will ship via a carrier that complies with all federal regulations, and the firearm will be transferred to you through your chosen FFL after ATF Form 4 approval.
Q: What is the FFL transfer process for this NFA item?
A: After purchase, you will need to select a receiving FFL dealer who is authorized to accept NFA transfers. You will complete an ATF Form 4 (or e-Form 4) with your FFL, submit fingerprints and a photo, and pay the $200 tax stamp. The transfer typically takes 6 to 12 months for approval.

Q: Is this firearm compatible with .223 Remington ammunition?
A: Yes, the SLR106-55PR is rated for .223 Remington and 5.56x45mm NATO ammunition.
