Review: Solid and accurate - This laser/light combo is everything you want in a rifle setup. Laser is strong and white light is super bright. Easy mounting and set up. CT knocked it outta the park with this one. Highly recommend!
Review: Great product. Not compatible with Magpul MOE handguards - Really happy with this product once I did some tweaking. The product out of the box does not fit on a Magpul MOE handguards because the screws are to short and the contour of the housing is designed for a picitany rail even though it says it's compatible for both mlok and pic rail. I ended up doing a side mount because the top mount blocked my optic. Not because the CMR housing is big. It's actually very low profile, I'm just not running a riser on my red dot because of the more compact setup I'm running. With the side mount I had to purchase some significantly longer screws to get it to reach and that caused some extra pressure on the handguard. No big deal but the extra pressure pushing back caused the screws to come loose. Nothing a little lok tight can't fix. All in all the performance is amazing. The buttons have a nice tactile feel and click. The light is adjustable and remembers which light setting it was on last time you used it so you don't have to change it every time. The laser is very visible even in day light. I love this combo definitely worth the price. I have noticed the tan one fluctuates a lot in price so if you keep an eye on it you can get it for a a great deal.

## Questions & Answers

**Q: Is it waterproof?**
A: I have had mine out in some pretty good rain storms with no issues.

**Q: Does anyone know what type of battery it uses?**
A: It takes an 18350 with an integrated micro USB port for recharging. 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.

### ⭐⭐⭐⭐⭐ Very good
*by T***Y on March 28, 2024*

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.
