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!

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.

Very good
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.

Pressure switch
Pressure switch does not work properly. It does not seat correctly. If you push connection into device while clicking it it works but as soon as you release pressure it will not work. Seams the connection stem is too short. Device works break except for the damn switch. Seems to be a ln issue with manufacturing since I’ve seen a lot of bad switch reviews.

Not bad. Design could be improved
Unit overall, I'm buying another one of them. Pros: after being knocked around in a soft case, holds zero well. Design lends well to a top rail mounted placement. Duel mounting design 1913 or M-lock. Light has a great spill. Laser is closer to bore axis than other units. Button on rear center of unit. Rear lock out light, laser, or both switch. Cons: 1913 rail mounting system, plastic parts at this time are brittle and broke easy. (To crimson traces response for a fix, excellent and quick.) M-lock, much better. Light, no real hot spot. Remote switch is almost usless. Battery life and battery. Overall: I've got consistent hits 0-85yards with the laser in low light to dark. Light has a lot of power for size, but a bright flood. Good for CQB to 100 yards max! Broke plastic 1913 piece with only slight finger pressure. Crimson trace quicky replaced it. To install pic-rail mount, heat rail and plastic part with a hairdryer to very warm before attempting to tightening to inch pounds spec. Remote switch is, well, junk. It's hard to get to lock in place, even with replacement with updated o-ring. Center rear button works fine for either left or right shooting. Hope this helps.
