Received my combo laser in the mail last week; so far not so good. The remote pressure switch does not work, contacted opticsplanet about the issue, still waiting to hear back from them. The combo laser itself works fine; it is very light, mounts low enough not to interfere with optics or BUIS. The only issue if you mount it on your top rail the green laser will not clear your front sight; I tried two different sights, Troy and Magpul, would not clear either of them. I wanted to keep as much weight close to my body as possible, had to reposition front sight to mount combo laser in front. The item itself seems sturdy and well built (except for the remote pressure switch), will update once issue resolved.
Pros: Light, Low Profile
Cons: Laser does not clear front sight, Remote pressure switch does not work
