Best Compact M-LOK Rifle Light – OLIGHT Odin Mini
The OLIGHT Odin Mini suits shoppers comparing compact weapon mounted lights for an M-LOK rail. Its listed peak output is 1,250 lumens with a 240-meter beam distance, and it comes with a magnetic remote pressure switch.
Best For: M-LOK rifle setups where a short light and included remote switch are priorities.
Pros:
- 4.55-inch listed light length keeps the setup compact.
- Included M-LOK mount uses a slide rail and mechanical lock.
- Magnetic USB charging and IPX8 water resistance.
Cons:
- Uses an OLIGHT customized battery.

The Odin Mini is a practical choice if its included mounting hardware matches your rail. Check the battery and mount requirements before choosing it over a more flexible setup.
Best Small Rail Light – OLIGHT PL-Mini 2
For buyers seeking small weapon mounted lights, the OLIGHT PL-Mini 2 offers up to 600 lumens and a 100-meter beam distance in a 2.56-ounce body. Its adjustable rail adapter helps position the light on compatible GL or 1913 Picatinny rails.

Cons:
- Built-in battery is not removable.

The PL-Mini 2 makes sense when a small footprint takes priority over maximum output. Confirm the rail fit on your specific setup before buying.
Best High-Output GL/1913 Light – OLIGHT PL-3R Valkyrie
The OLIGHT PL-3R Valkyrie is a higher-output pick among weapon mounted lights for GL and 1913 Picatinny rails. It delivers up to 1,500 lumens and 10,200 candela, with an adjustable mount and interchangeable rail inserts.

- At 3.19 inches long, it takes up more space than the PL-Mini 2.
Pick the PL-3R when output and mode selection outweigh the appeal of a smaller light. Its included rail options also make it worth considering if you use GL or 1913 hardware.
Wide-Beam Pick – Streamlight TLR-1 HL
For buyers comparing weapon mounted lights, the TLR-1 HL combines a 1,000-lumen wide beam with 20,000 candela and a rated 283-meter throw. Its rail-key kit covers several listed rail types, but check your firearm’s rail before ordering.
Best For: Buyers who want a wide, bright beam and a tool-free rail clamp.
Pros:
- Rated for 1.5 hours on high using two included CR123A batteries.
- Ambidextrous momentary and steady-on switch.
- Machined aluminum body with IPX7 waterproof rating.
Cons:
- Non-rechargeable model requires replacement batteries.

Choose this model when beam width and runtime matter more than a compact profile; its listed length is 3.39 inches.
Among weapon mounted lights here, the TLR-7 HL-X offers a rechargeable option with 1,000 lumens, 22,000 candela, and a rated 297-meter beam distance. Use Streamlight’s fit guide to confirm compatibility before buying.

This is the stronger match if rechargeability and rated reach are priorities, provided its shorter high-mode runtime meets your needs.

Among weapon mounted lights for rifles, the HL-X Pro stands out for its included M-LOK mount and Jack-Cap controls. Its 1,000-lumen, 50,000-candela beam is rated to reach 447 meters while retaining useful peripheral illumination.

The HL-X Pro is the practical pick here if the included mounting hardware and Jack-Cap control options matter as much as beam reach.
Best Picatinny-Rail Pick – Streamlight ProTac Rail Mount HL-X
The ProTac Rail Mount HL-X is a straightforward choice among weapon mounted lights for compatible MIL-STD-1913 Picatinny rails. It pairs a 1,000-lumen, 50,000-candela beam rated to 447 meters with both remote and tail-cap switches.
Best For: Picatinny-equipped long guns whose owners want included switch options and programmable modes.
Pros:

Best Lighter-Weight Option – Streamlight ProTac Rail Mount 2
If weight matters more than maximum output, the 4.96-ounce ProTac Rail Mount 2 is worth comparing with larger weapon mounted lights. Its 625-lumen, 22,000-candela beam has a stated reach of 297 meters, and its integrated mount fits standard 1913 Picatinny rails.

Pros:
- Weighs 4.96 ounces according to the supplied specifications.

This is the more compact-output trade-off of the three: less stated beam reach, but lower listed weight and versatile included controls.
How We Picked These Weapon Mounted Lights
This selection covers pistol and rifle lights from OLIGHT and Streamlight in a range of sizes and power configurations. We organized the choices around practical shopping questions: which rail or mounting system they fit, how accessible the controls are, whether the light uses rechargeable or replaceable power, and how much space it takes up. Published lumen figures provide context, but they do not tell you everything about usable beam distance or runtime. Check the manufacturer’s current specifications for those details before buying.
Quick Comparison: Start with Your Platform
For a pistol, begin with the OLIGHT PL-Mini 2 or PL-3R Valkyrie, or Streamlight’s TLR-1 HL, TLR-7 HL-X, and TLR-7 X. The smaller models may suit setups where front-end bulk matters, while larger models may be worth considering if you have room for them. Confirm rail fit and holster support for your exact pistol and light combination.
For a rifle with M-LOK mounting space, look at the OLIGHT Odin S and Odin Mini. Streamlight’s ProTac Rail Mount HL-X Pro, HL-X, and Rail Mount 2 are other rifle-oriented options. Compare mounting hardware and switch arrangements rather than assuming every package includes the same accessories.
Key Buying Factors for Weapon Mounted Lights
Mount and Fit
Identify your rail before comparing output. Pistol lights may use different keys or mounting positions for GL-style and 1913 Picatinny rails. Rifle lights may require a compatible M-LOK or rail mount. Check that the light clears nearby components and can be securely installed according to the manufacturer’s instructions.
Controls and Beam
Make sure you can operate the switch without changing your normal grip. On rifles, consider whether you prefer controls on the light or a compatible remote switch. Compare beam reach and spill for your likely environment; a high lumen rating alone does not guarantee the beam pattern you want.
Power, Runtime, and Accessories
Rechargeable batteries can reduce recurring battery purchases, while replaceable batteries may be simpler to swap when charging is unavailable. Verify accepted battery types, stated runtime at each output level, charging requirements, and any restrictions on mixing components. For pistols, check holster compatibility before purchase; a holster made for the firearm alone may not accommodate an attached light.
Who Should Buy Which Weapon Mounted Lights?
Choose a compact pistol light if you prioritize a smaller setup and can find a holster that fits it. Consider a larger pistol light if its size works with your firearm and you want to compare broader beam and control options. Rifle owners should shortlist models that match their available mounting space, then choose based on switch placement and power preferences. Whatever you choose, verify compatibility and safe installation with the firearm and light manufacturers’ instructions.
