   First order received the CMR 301 pro had a defective switch. We had to drive the defective product to an githubja.com drop off point (waste of fuel and time) Second product arrived, box missing all acceories, instructions and too top it off it had a used Iprotec light. We were not allowed to get a replacement because githubja.com appears to have what one would consider a do over! Now they will only give me credit card until they receive the crappy product they sent me. Add insult to injury it will take two weeks to possibly send me a replacement, why I didn’t make the flipping mistake! If there were 0 stars I would have given it to githubja.com for the major screw up! Total garbage!

   Tape switch doesn’t work unless you push in really hard and hold it. Other then that it works well. The listing description is inaccurate compared to crimson trace Website. It does include a rechargeable battery and cord. It has picatinny and mlok rails. It is bright and the laser is great. Need to test it’s zero hold ability. Waiting on a replacement due to the bad switch connection. Once a replacement is received and I test its zero hold I will update the review.

   Update. I received a new unit. The switch works. However can not adjust it enough to obtain a zero. There is just not enough adjustability. No matter where I placed the unit on the handguard. You can also move your laser by taking your finger and pressing slightly on the exposed adjustment screws. I love the design and price buts it’s not even worthy of a pellet gun at this point. Poorly made

   This contraption has been worth every penny! I have been using this laser for the past couple of years and I love it. The key is to zero in using your sights for the best possible accuracy. After that it is set it and forget it. Wherever you point the laser is where the projectiles will strike. Magnificent!

   The light itself is quite bright and has a good amount of flood, similar to the Surefire Scout M300. The green laser is strong and easily visible in daylight inside of 50 yards. It’s pretty light weight and low profile enough to mount on the top rail in front of or behind your iron sights. If you use a red dot, you can see the unit on the rail but it does not obstruct your view of the dot or the target. I haven’t ran it long enough to verify the battery life but I played with it for 15-20 minutes in the dark, outside checking the pattern, spill and reach and it recharged within a few minutes. That leads me to believe the battery life should be as advertised. The switch is decent and works fine but it doesn’t mount to 1913 as securely as I would like. I used some cable management rail cover clips from Larue Tactical to secure the excess cable because CT doesn’t supply anything to secure the cable or the switch other than its built in 1913 railmount which is rather flimsy. The selector switch on the unit changes between light, laser and light and light only or off. It works fine but it is almost TOO easy to change. I am concerned that it may be easily bumped out of the position you want it in. The adjustments to zero the laser do not have detents or clicks. I can easily turn them with my fingernail. I haven’t used the light yet to find out how well it holds zero under various conditions so that may or may not be an issue. As for the mounts, they are absolute TRASH. The picatinny rail mount (1913) is probably what most people will use as I think this style light laser is best mounted at 12 o’clock on the forend. The gun I attempted to mount this on is a factory original, mil-spec, S&W, not some Chinese knock off or copy. The CT 1913 mount broke immediately while attempting to put it on the rail, EXACTLY as the instructions tell you to do. Whatever material they used on the mounts is very brittle and poorly designed/made in China. Just for comparison, I put the other included mount (MLOK) on a different rifle to see how it matched up to the rail and it seems pretty questionable in the way it fit into the slots. So, the light/laser unit seems like a very good design with good potential and initial performance but if you can’t even get it on your gun it is worthless. Now that I have experience with the mounts, I would never trust this unit on a serious purpose rifle. I noticed at least one other reviewer had pretty much the same experience with his. CT needs to provide a solid, repeatable, robust, low profile mount that can be used on multiple guns and stand up to hard use. Also, I would suggest they make those adjustments and controls a little more resistant to being bumped out of whack. It is a good design but it needs some tweaking and it needs a much better mounting system. I would suggest making them in the US. This experience is exactly why I keep going back to Surefire products. They are expensive but they are very well made in the US and they stand up to very hard use and just keep going. I really wanted to love this Crimson Trace product even though I knew going in the CMR 301 was made in China. I have been using their Laser Grips for years without a single problem.

   This thing is worth the money. I love it. Works great. Just know if you only have m-lock rail you will need a small length of pictinny rail for the pressure switch. Can’t beat the price.

   Powerful light, green laser, thin, light, and esthetically pleasant “pro” look.

   Full disclosure: I’m a (now) civilian with a few years military under my belt who now LARPs and trains and plunks with various platforms.

   I had some disposable income and figured why not buy a laser for me freedom musket… Saw a few options for up to $300 but then got this a a great price… Forgot on which holiday sale… And have no regrets about the purchase.
   Laser and light are string and bright.
   Manufacturing seems tough and sturdy.
   The pressure switch works without issue besides the ergonomics being a bit bulky
   The plastic mounting hardware is suspect But I’m not running 72 hour missions either.

   All in all… I’d say good to use recreationally and on a patrol rifle or truck gun.

   Would buy again. Dabiting 2nd purchase for another platform.
