Things are coming along. I bought a
Magpul Rail Light Mount, as it can accommodate a range of flashlight sizes. I realize I can get something with an integral rail mount, but I’ll actually get more use out of this as a non-gun flashlight.
I ended up getting a Streamlight ProTac HL-X. I was able to remove the pocket clip and mount it in the Magpul mount.
I had originally intended to mount it on the topcover rail, offset to the right side, in front of the optic. But the mount hit the side of the topcover next to the rail. I would have had to do some surgery to make it work.
Before I tried that, I tried it on the small rail I have that attaches to the bayonet lug. I usually use this rail to attach a front grip, and the light mount fits and still just leaves room for a grip.
Mounted this way the light hangs off the left side of the gun, and the end of the light sticks out just a little farther than the end of the barrel. It also hangs out far enough that the shadow from a mounted suppressor really is not noticed at all. This is pointed at the floor. When it’s more than a few feet away you really don’t notice it.
The button at the rear of the light is easily accessible, but not really a natural reach when holding the gun. This might be a problem if I was all tacticool and busting down doors and stuff. But I expect I’ll just turn it on, wait for the timer to beep, and leave it on while I proceed to shoot steel and cardboard targets. When I’m done I’ll turn the light back off.
