The Laserspeed brand – established and used by the Chinese Dandong Xunlei Technology Co. company for its products since 2008 – is mostly known in Europe and north America for its consumer-oriented, budget-priced laser sights and tactical flashlights, some of which are sold at such a low price tag, they’ve become a staple of the MILSIM and Airsoft markets.

And yet, the Company is perfectly capable of manufacturing much higher-tier products, aimed specifically at a professional (MIL/LE/Govt.) clientele: that’s the case for the Laserspeed LS-FL5 multifunction laser sight, one of Laserspeed’s latest products, which we at GUNSweek.com were among the world’s first to try.

At a glance, the Laserspeed LS-FL5 is remarkably vanilla in terms of layout and design, being very similar to basically any other rifle laser out there. Standing in at 11 centimeters (4.33”) in length, 7,7 centimeters (3.03”) in width and 3,7 centimeters (1.46”) in height, the LS-FL5 is also pretty much on the large side if compared to other similar products marketed internationally by competitors such as Sightmark.

And yet, compared to its most direct competitors on the commercial market, the Laserspeed LS-FL5 stands on a class of its own, with an 830 nm, 20 mw infrared laser and a 510 nm, 5 mw visible laser; that would make it an extremely powerful device already, but a more powerful, high-output 8 mw function has been launched in June 2023.

The Laserspeed LS-FL5 is built around a matte black, 6061-T6 aircraft-grade aluminum alloy body that weighs in at barely 298 grams (10.51 oz), making up partially for the relatively large size. The battery adds but a couple of grams to the overall weight: the LS-FL5 is powered by a single, rechargeable 18650 battery, which is not included in the package.

The device will operate on two commercial CR123A batteries in case of extreme emergency, but the manufacturing company urges users to avoid using CR123As on the LS-FL5, as the use of batteries for which a device is not certified may damage the electronics and is generally not recommended on any device.

The Laserspeed LS-FL5 can be installed on a Picatinny rail through an integral, machined interface that is tightened by a large-headed Hex screw. An easy and practical solution under the engineering and manufacturing point of view, which also has the advantage of allowing the device to maintain a low profile – particularly if installed above the bore axis of a rifle rather than to one side of the handguard – but with the classic drawbacks of requiring a Hex key for removal and posing the risk of stripping the screw in case of mishandling, particularly on the field.

A quick-detach bracket would definitely be an improvement, but with the battery compartment and its screw-on metal cap located on the rear of the device, you may not need to remove the LS-FL5 from your gun very often, if at all, once installed.

Also to the rear of the device is a protected connector that allows the use of the issued remote switch, with a 38 cm (approx. 15”) cable. The third and final element located at the rear of the body is the manual spot width adjustment dial for the IR illuminator.

The visibility is absolutely excellent for all sources. The visible green laser is extremely daylight-visible; in a bright, super-sunny summer day the maximum effective range may be slightly reduced, but not dramatically. The IR laser is extremely effective even when looked at through a less-than-top-notch IR vision device, and the illuminator is as bright as it can be, making the night world look like broad daylight with your usual shade of green or grey. For everything from night shooting competition to night hunting, down to law enforcement applications, the Laserspeed LS-FL5 is an extremely powerful and versatile tool.

All emitters are protected by a set of rubber caps that are secured to the body of the device so they can’t get lost. As an alternative to the remote switch, a built-in activation button is located on top of the device; two separate switches allow the user to navigate and select between different options of use.

The Laserspeed LS-FL5 multifunction laser device is IP68 certified from factory against dust, water, and moisture, it will remain operational at extreme temperatures (-20°C/+55°C, or -4 to 131°F) and has been tested in factory to withstand recoil up to 1,200 G – which is the recoil level of .50 BMG, or 12.7×99mm NATO, fired from a heavy machine-gun or a semi-automatic, short-recoil operated rifle such as the Barrett M82-A1.

This means that the Laserspeed LS-FL5 will not only withstand the recoil of standard military small arms and modern hunting, sport shooting and personal defense rifles – we tried it with 5.56×45mm, 7.62×51mm and 7.62×39mm platforms without as much as a hiccup – but will also resist the hard recoil of long-range, high-caliber rifles.
