Crimson Trace CMR-301 FDE Railmaster with Green Laser, Adjustable 1000 Lumen LED Flashlight and Rechargeable Battery for Shooting, Competition and Range

Mounts easily -- easy to align -- provides good brightness out to 15 yards -- have not tested any further

Thing works extremely well, and considering it's under $250, it's pretty awesome. I used the Pick mount and tape switch. No issues at all firing 450+ rounds in under 4 hours during a carbine course.I would like to say something about a review mentioning a "vertical or horizontal offset". Every aiming laser, from a Harris ATPIAL to a no-name airsoft has an offset. The laser should be mounted parallel to the barrel so that the laser point and the point of impact are a known constant. Intersecting the POI with the laser at X distance is useless unless you are exclusively shooting from X distance, which is ridiculous. However, if you know your POI will always be 1" left and 2" down from your laser point, you now have something useful screwed to your blaster.

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.

Nice laser light unfortunately the plug-in control broke almost instantly. If they had an aftermarket control for it, it would probably be pretty decent.

Great laser/light for the price! I’ve always had good experiences with Crimson Trace. Push pad is great and easy to mount.

Product was broken upon delivery with the pressure switch not working, I ordered a replacement and they said it was delivered, I never received my replacement and never got a refund from the seller.

Fits perfectly and very high quality laser light combo. The only thing that doesn’t make it perfect is the color, I wish they could offer it in fde color, it’s bronze. But other than that very satisfied with this combo.

Great bright green laser light, powerful flashlight, and holds zero well. Only issues I had was the fluctuation of the price of this thing (seemed like a few times a day the price would change) and the green laser needs to be on the flashlight side of the box. Because rhe green laser is on the left side of the box, it is on the inside of my rifle, as I am right handed. When it gets time to shoot, I grip my hand guard with my left hand on my AR and my thumb gets in the way of the green laser. I have to adjust my hand or use a grip to prevent this. Not a dealbreaker, but it is something to think about.
