The Arisaka Defense Story: Military Heritage Meets Engineering
Walter Fowler and William Roberson didn’t just stumble into the firearms industry—they grew up in it. Walt’s childhood moved between Air Force bases while Will followed his Army family from station to station.
Both their fathers served in Vietnam, and the military tradition runs even deeper. Will’s grandfather served on the USS Arkansas and USS Shangri-La during WWII, while an uncle fought with the legendary 442nd Regimental Combat Team.
As Japanese Americans, choosing the name Arisaka carried special meaning. They wanted to honor Arisaka Nariakira, one of Japan’s most respected weapons designers who revolutionized rifle design in the late 1800s.
The company operates on cultural principles that shaped both founders: perseverance, teamwork, harmony, and family. These aren’t just words on a mission statement—they guide every design decision and manufacturing process.
Every Arisaka product is designed, tested, and manufactured on their own CNC machines in the USA. This complete in-house control means they’re not dependent on contractors who might cut corners or miss quality issues.
Their design philosophy centers on eliminating unnecessary bulk while maximizing functionality. When you pick up an Arisaka weapon light body, the difference becomes immediately obvious—it’s lighter and more streamlined than anything else with Scout compatibility.
Understanding Arisaka’s Modular Advantage
SureFire established the Scout light pattern that became the industry standard. Their design uses standardized mounting lugs underneath with separate heads, bodies, and tailcaps that interchange.
The problem? SureFire’s bodies include integrated Picatinny rail clamps that add bulk exactly where you don’t want it. This creates clearance headaches around front sights and accessories.
Arisaka manufactures light bodies without the bulky Picatinny mounting interface. This dramatically reduces the profile while maintaining Scout mounting lug compatibility underneath for aftermarket mounts.
You get better front sight clearance when using Arisaka’s mounts on handguards with 45-degree mounting surfaces. You can also position lights closer to your handguard without interference.
Bodies work with SureFire heads, Malkoff heads, Modlite heads, and Arisaka’s offerings. Any Scout-pattern tailcap fits, including options from Unity Tactical and Modlite.
This means you’re not locked into proprietary ecosystems. Build exactly the light you need, then upgrade individual components as technology improves.
Arisaka Light Body Options: Choosing Your Platform
300 Series: Ultimate Lightweight Champion
The 300 Series body weighs just 0.5 oz—the lightest Scout-pattern body available. This Arisaka light body uses 6061-T651 aluminum with MIL-A-8625 Type III hard coat anodizing for durability.
Compatible heads include the Malkoff E1HTv2, producing 400 lumens with 18,000 candela. The SureFire KM1-E offers 250 lumens of white light plus 100mW infrared with a bezel twist.
Runtime reaches 45-60 minutes with a single CR123A battery. Single-cell lights can’t match two-cell alternatives for brightness, but the weight savings shine in competition and dynamic shooting.
For serious weapon lights applications, consider whether this output compromise works for your needs.
600 Series: Best Value Platform
The 600 Series accepts two CR123A disposable batteries or a single 16650 rechargeable cell—giving you true dual-fuel flexibility. Arisaka founder Will Roberson calls this “the best price/performance choice” in their entire lineup.
Compatible heads include Malkoff’s E2HTv3, delivering 1,000 lumens with 30,000 candela. The beam pattern features a perfectly round hotspot with a smooth spill transition that doesn’t create harsh edges.
The E2XTv3 bumps candela to 55,000 while maintaining 1,000 lumens for situations where you need extra throw distance. Runtime reaches 60 minutes on 16650 rechargeable or 30 minutes on two CR123As.
The 600 Series maintains full SureFire M600 compatibility with existing heads if you already own Scout accessories. This backward compatibility protects your investment when upgrading from traditional Scout lights.
18650 Series: Maximum Performance
The 18650 Series accepts single 18650 rechargeable batteries (3,500mAh) or two CR123As as backup. Compatible heads include Modlite’s PLHv2 (1,350 lumens, 54,000 candela) and OKW (680 lumens, 69,000 candela reaching 500+ meters).
Malkoff’s HTL outputs 800 lumens with 30,000 candela—Arisaka’s favorite beam pattern with a perfectly round hotspot. Runtime extends to 60-75 minutes depending on head choice.
Arisaka recommends the 18650 Series “for all uses unless you want a smaller/shorter light.”
18350 Series: Compact High-Output
The 18350 Series uses 18350 batteries (1,200mAh) instead of 18650 cells. This shorter package works perfectly on 10.5-inch and 11.5-inch barrel platforms.
Runtime drops to approximately 35 minutes versus 60-75 for 18650. You maintain head compatibility while cutting length and weight.
Malkoff Partnership: Fully Potted Excellence
Malkoff Devices specializes in fully potted LED assemblies. Their potting compound encapsulates electronics, protecting against shock and vibration that destroys standard lights.
The E1HTv2 (300 Series) outputs 400 lumens with 18,000 candela. The E2HTv2 (600 Series) delivers 800 lumens with 30,000 candela.
The E2XTv3 increases candela to 55,000 while maintaining 1,000 lumens. For the 18650 Series, the HTL outputs 800 lumens with 30,000 candela using either 18650 or CR123A batteries.
Modlite Compatibility: Premium Integration
The 18650 and 18350 Series work seamlessly with Modlite heads. These Arisaka weapon light configurations deliver exceptional performance.
Modlite’s PLHv2 produces 1,350 lumens with 54,000 candela—excellent balance between throw and spill. The OKW specializes in extreme throw with 680 lumens and 69,000 candela, though this creates tunnel vision at close range.
Both heads feature dual-fuel capability. Full output requires 18650 or 18350 batteries, while two CR123As provide reduced but functional backup power.
Patented Mount Solutions: Solving Real Problems
Inline Scout Mount: Lowest Profile Available
The Inline Scout Mount creates the tightest fit at just 0.20 inches above the mounting surface. This Arisaka light mount weighs 0.6 oz and measures 3.4 inches long.
The Inline excels on handguards with 45-degree M-LOK or KeyMod slots like Geissele MK8/MK16 and BCM MCMR. MAWL users benefit particularly—the mount tucks lights underneath without interference.
However, the Inline doesn’t work with ATPIAL-C, PEQ15, or DBAL-A3 lasers. These need the Side Scout Mount instead.
Offset Scout Mount: Versatile Workhorse
Arisaka’s founder calls the Offset his “favorite light mount” for strength and versatility. This mount positions lights at 1:30/10:30 or 4:30/6:30 clock positions with three lateral positions spanning 0.240 inches of adjustment.
The Offset measures 1.265 inches long and under 0.20 inches thick with tapered Torx screws that resist loosening. Most M-LOK and KeyMod handguards work perfectly, except Aero Precision Enhanced Gen 2 and standard SIG MPX/MCX Virtus handguards.
Side Scout Mount: Laser Integration Specialist
The Side Scout Mount positions lights directly below ATPIAL, PEQ15, and similar laser units. It also clears NGAL and Steiner DBAL QD levers.
Arisaka describes this as “the most durable mount we make” due to its secure attachment method. Choose the Side Mount when running laser/illuminator setups.
