On pistols, I know many trainers who’ve had very good experiences with visible laser sights on pistols. The late Todd Green was a big fan, for example. Laser sights work well for target-focused shooting and shooting problems involving unusual shooting positions. They also reduce time to first shot, which is big from a defensive standpoint.

Do they make sense on a carbine?

Clearly, the answer is yes if one is using night vision devices. IR lasers are tops at night, if you’re hunting hogs or scum.

What about visible lasers? Visible lasers can be had for a lot less than IR ones. That much is obvious. Also, the nature of the laser means that a red dot or low power variable optic will make the most sense as the primary sight for most. If one had a gas mask on, the laser would be a much better choice as a primary sight.

This points to some of the use cases that might make lasers helpful. The laser will naturally make shots from nonstandard positions easier, because we don’t have to get all the way behind the gun to get a good sight picture. The laser can help.

We might also expect the laser to help on getting faster first shots, because we don’t have to get the rife all the way up before getting our initial shot off. I would love to test this in match conditions. And yes, this is a very gamer reason for a laser. Yeah, I’m a gamer.

Another thought for the laser is as a backup sighting device. We love backups. Normally, people mean ‘backup iron sights’. But iron sights are very different from a red dot or other optical sights. Lots of people have backup irons on their guns, but don’t practice with them. I’m pretty sure plenty of people don’t even zero them. Or, you could use a laser, which is going to give you a similar ‘colored dot in a tube’ as your red dot.

A brief word on sight models. As usual, there are some high end military type models available for quite a bit of coin. For experimentation purposes, I’m not going to be getting one of these. I’m going to start with a Crimson Trace Railmaster, which is a bit cheaper than a high-quality BUIS set. It’s not as durable as an ATPIAL, but it’s a lot cheaper. And it should let me evaluate the concept fine. Given my expected use cases, I’m not concerned about the relative lack of durability.
