The laser cartridge works great and I would suggest buying that seperately. The target has a swith to set for exhisting light and is hard to set by trial and error. The black shroud you see on the center pic to the left of the target is used to place over the target and to shade the lens from light, doesn't fit the target properly and the holes for the switches are too small and hard to line up and keep in alignment as you move the target. Seriously , it is a useless joke. The item you see on the right is a cardboard light shroud I handmade and it works well. I reccommend the Laser cartridge but not the target that requires the usless light shroud that comes with it.

UPDATE: after leaving my original review, the seller contacted me and offered to ship me a replacement of the .45ACP version. The replacement worked perfectly. No issues at all. It looks like the original one I received may be an older version? It looks completely different. The one with the larger O rings is the replacement that works great. A+ customer service I bought both the 9mm and .45ACP versions of this laser. The 9mm version works great, no issues. Unfortunately, the .45ACP version' laser does not shoot straight. I mounted my 1911 in a vice and compared the laser to real ammo. The laser points slightly right.

I received the organizer promptly as ordered. As usual Magpul makes an excellent product. The foam appears quite durable. I was concerned it would be flimsy Styrofoam, and come apart quickly. I don't believe it will. This system is pure genius, once the manufacturing process gets up to speed the various blocks become available this give you endless configurations! The only issue is they sent the incorrect part as seen in the images by ngclab.com. Deal with Magpul directly for THIS product to ensure the proper item. I tried to make it work to no success. I contacted the CS, and Cory took care of me. Once he confirmed everything was messed up, he sent out the correct model. This one is correct and fits like a glove! I'm looking forward to years of service from this allowing me to reconfigure for various rifles! Bravo!

It was a little pricey but worth the cost. Very easy to use, lightweight, and I would have never gotten this bad boy while stalking without it.
