Guns & Gear Podcast Reviews the INFORCE ARC

When a show like Guns & Gear covers your product, you pay attention. Ryan Gresham, Chris Cerino, and Kevin "KJ" Jarnagin have built a reputation over hundreds of episodes for putting gear through genuine scrutiny rather than simply reading off spec sheets, and in Episode 631, the show's hosts spent a significant stretch of the conversation on the INFORCE ARC series. The verdict was that the ARC is a flat-out impressive weapon light that punches well above its price bracket.

Initial Thoughts

The review opened with an admission that INFORCE lights from years past were "okay" — solid enough, but not necessarily the first name that came to mind when shopping for a serious weapon-mounted light. The ARC series changed that picture entirely. "Their long gun weapon lights now are pretty hot," set the tone for the rest of the discussion, and the rest of the review backed that up point by point.

Hands-on time with the ARC 650-LR-M focused on four main themes: output and beam quality, scout-pattern compatibility, the dual-fuel power system, and build durability. These happen to be exactly the areas where the ARC was designed to earn its keep.

1,400 Lumens, 90,000 Candela — and a Practical Read on Both

The review walked listeners through the 1,400-lumen initial output and 90,000-candela peak beam intensity, but what stood out was the care taken to explain what those numbers actually mean in practical terms. High candela means a tightly focused hotspot. 90,000 candela tells you the ARC is pushing more of its light into the throw rather than scattering it as wide spill. This means the ARC has a genuinely useful compromise: enough throw to engage targets well past 200 yards, with spill lighting that keeps close-quarters awareness intact.

On range capability, INFORCE rates the 650 for a 600-meter beam distance. In the real world, this means usable illumination at roughly half the rated distance — the ARC held up squarely to that expectation, with clean target identification at 200 yards and solid illumination well beyond 300. For a 16-inch 5.56 AR, which was where it was mounted, that performance made good sense.

There was also talk of photonic barriers, something that often gets overlooked in weapon-light conversations. A high-output light can punch through tinted glass in daylight, making it useful for vehicle-based threats in ways that most light buyers don't think about until they need it.

Modular Compatibility

The ARC 650's compatibility with the Surefire Scout footprint and thread pattern came up repeatedly as one of the strongest reasons to choose it over comparably priced alternatives. Because the light uses the same threading and bosses as a SureFire Scout, any aftermarket head, tail cap, or pressure switch built for that platform drops right onto the ARC without modification. The ARC has been tested with various Scout-compatible parts, and every one of them threaded on and functioned without issue.

Scout compatibility means the ARC 650 can accept compatible heads from other manufacturers, giving users a path to a significantly extended range from the same body they already own. For buyers who want to future-proof their weapon light investment, that kind of interoperability is a meaningful differentiator.

The included 45-degree M-LOK mount was called out specifically as a welcome addition — not having to source it separately was a point in the ARC's favor from the moment it arrived.

Dual Fuel, Lockout, and Build Quality

The dual-fuel capability — 18650 rechargeable primary, with two CR123A batteries as a backup option — drew straightforward praise. The reviewer tended to carry a spare 18650 for extended use, but having the CR123A fallback in the field represents a meaningful safety net for anyone who can't guarantee reliable access to a charger. The included battery runs for approximately two hours and 45 minutes on high, which is a runtime the review compared favorably against other weapon lights in and above the ARC's price range.

The quarter-turn lockout mechanism received a solid mention as well. Rotating the head slightly disables the light entirely, preventing unintended activation during storage or transport. Combined with the recessed button design that resists accidental engagement, the ARC 650 manages its own safety without requiring anything from the user except knowing the system.

On durability, the review noted that the IPX8 waterproofing rating exceeded what some higher-priced name-brand competitors offer — a point that landed clearly in the value-per-dollar argument the ARC makes throughout the conversation.

The ARC 350-LR-M: Same Idea, Smaller Package

The show gave a brief but accurate read on the ARC 350-LR-M as well. It runs the same Scout-compatible architecture, the same industry-standard head and tail cap interface, and the same overall design philosophy as the 650, but in a shorter, lighter package powered by an 18350 rechargeable cell. The tradeoff is runtime and output: the 350 produces 1,200 lumens and 75,000 candela, with a rated runtime of 45 minutes on high and a beam distance of 529 meters. For shooters running a shorter barrel who need a tighter, more compact light, the 350 fills a real gap without sacrificing the modularity that defines the ARC line.

Final Thoughts

Guns & Gear isn't in the habit of handing out high scores as a courtesy. High praise from a panel that includes instructors who run low-light training courses and have strong opinions about weapon-light technique reflects genuine performance under evaluation. The review's only meaningful criticism was price, and even then, it was acknowledged that the ARC 650 sits in a reasonable middle ground between budget lights and premium name brands — and it was concluded that the Scout compatibility alone narrows that price gap considerably.

Both the ARC 350-LR-M and the ARC 650-LR-M are available at inforcelights.com, through Midway USA, and at select retailers nationwide. Episode 631 of Guns & Gear is available wherever you listen to podcasts.
