I bought some online from Weltool, about $14.00 each, delivered in about one week and work fine. I have 2 of the railmaster 301, I screwed them directly to my AR pic rails instead of using the plastic adapter, very good units for the price. **Q: Does the light have a strobe function?** A: Unfortunately, this product does not have a strobe mode. **Q: What material is the body made out of? I seen a video on youtube, stating they were aluminum but the older ones were polymer?** A: They are all aluminum bodied, except for the remote pressure switch which is polymer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid and accurate *by J***L on October 31, 2025* This laser/light combo is everything you want in a rifle setup.

Very dependable. ### ⭐⭐⭐⭐ Incredible value for the price *by T***T on March 8, 2022* I now own 3 of these, all of which have been purchased for different prices. The price seems to fluctuate quite a bit on these an I'm not sure why. Even at the highest price I paid for one of these, it's still worth the money. I was toying with the concept of having not just a light but a laser also for some time and decided to give one of these CMR-301s a try. One of my biggest regrets is having waited so many years before trying a laser. I was told so many times that lasers were silly and that it will slow you down. After shooting a couple of practice sessions and a competition with this light/laser combo, I have found my results to be the opposite of what I was told my whole life. All of us running lights and lasers, basically for our first time, all found it to be faster. Just shoulder the rifle like you normally would, but instead of looking through an optic, just use the laser instead. I also found this to be a huge help when engaging multiple steel plates from the same position. Even though I could easily see the steel plates when illuminated with the white light, once I look through my red dot sight, it was really hard to make out the targets. Once you start firing, you will be surprised at how much smoke is in the air because this isn't something you see during the day time. The more you fire from that same position, the worse it gets and the harder it is to see through your optic. But using the laser without looking through the red dot made it so much easier to make out the targets in that smoke and engage the plates at 100 yards. Easier translated to faster. The light output is decent. It says 1000 lumens, and it very well could be that, but it is more of a flood light rather than a spot light. I only engaged steel plates out to 100 yards, but I'm not sure how much more throw this would have beyond that. But it was plenty of light to still identify and effectively hit the 2/3 IPSC plates at 100 yards. The laser is green, which is what I prefer. I have a light and laser I run on a different rifle, both of which were quite a bit more expensive than this Crimson Trace, but the red laser was more difficult to see even though it's rated at the same output (5MW). At night, the CMR-301 laser is plenty visible and I could see it illuminate on a mountain range that was well beyond our 100 yard target. Keep in mind that these are not really daylight visible due to FDA restrictions so you will need to zero this laser in low light conditions. The mounting system is plastic and was a concern of some reviews I read. I have not experienced an issue yet with either the MLOK mounting plate or the Picatinny mounting plate. Both lock down extremely well and I have not yet lost the zero on the lasers. It's important to note that the underside of the CMR-301 is shaped to fit the octagonal shape that many handguards have. So on something like a CZ Scorpion Evo Micro with an HBI handguard, even though the handguard sides are M-LOK, because of that octagonal shape to the underside of the CMR-301, I could not get the M-LOK mount to work on the tall and flat surface of the HBI handguard. On flat surfaces like that handguard has, you will need a picatinny section to go into the M-LOK slots and it should hopefully mount that way. I don't see this being an issue for most M-LOK AR handguards since they usually have that octagonal shape. The battery is rechargeable and I absolutely love that CT decided to do this. I am tired of feeding my lights disposable lithium batteries. So far I have no had any issues with these lights killing the batteries when not in use. I had looked at some other light/laser combos and this was an issue with some of those units killing batteries in a matter of days. I like that CT also gives you the option to select if you want the light by itself, laser by itself, both, or off. I just run both but it's nice they gave that option. I do appreciate that the back of the light laser has a push button so that you are not required to use the pressure switch. On one of my rifles, the rail space is limited so rather than using the switch, I just activate the light/laser with my thumb. CT was smart and also designed this to have momentary (you just hold the pressure switch or keep pressure on the push button), or constant on by clicked the push button or by tapping the pressure switch. If you have the pressure switch installed, you can still use the push button. That was also clever so that if the pressure switch malfunctions, you have a backup way to still activate the light. The biggest thing I wish they could improve on is the switch itself. The light/laser combo has both MLOK and Picatinny mounting options, but the switch is only picatinny. I prefer running the light/laser at 12 O'clock, but this isn't possible on something like MY CZ Scorpion Evo Micro. Instead, I mounted the light/laser combo on the side of the handguard (I chose 3 O'clock). I didn't like the switch on the sides of the handguard because they are M-LOK and would first require a section of M-LOK compatible picatinny. This makes the switch sit too far out from the handguard surface and makes it uncomfortable and awkward to activate the switch. I ended up putting the switch at 12 O'clock, but it is quite the reach on a tall handguard like the HBI handguard I have. It's really hard to beat this light/laser combination especially for the price. Hopefully they hold up over time and extended use but so far, I have been very happy with them. ## Frequently Bought Together - Crimson Trace CMR-301 FDE Railmaster with Green Laser, Adjustable 1000 Lumen LED Flashlight and Rechargeable Battery for Shooting, Competition and Range - Guardtier CGM909 Pressure Switch Cable Guides Compatible with M-LOK System, Flashlight Laser Wire Management Clips 8 Pack - Black - Crimson Trace CMR-301 Railmaster Pro with Green Laser, Adjustable 1000 Lumen LED Flashlight and Rechargeable Battery for Shooting, Competition and Range --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/342017194-cmr-301-fde-railmaster-with-green-laser-adjustable-1000-lumen](https://www.desertcart.hr/products/342017194-cmr-301-fde-railmaster-with-green-laser-adjustable-1000-lumen) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
