Hi, found this thread through a google search. I had just made a thread on FalFiles dealing with this exact subject, showing a simple, cheap, easy solution I found. Total cost to me was about 6 or 7 bucks (not including the light itself). Oh, and I took it to the range and the light and mount held up just fine.
So, I am going to repost my thread from there, here (if that's okay). Keep in mind I have the StG-58 style handguards, but I am certain that the standard handguards can be worked with as well with some slight modifications to my approach... maybe?? I dunno, I'll have to try it out on another set of handguards...
Anyway, here it is - 6-7 dollar flashlight rail mount for StG-58 style FAL -
(original posting on FalFiles begins)
So, I'm out at Wally World and I come across one of those scope rail mounts for a Remington 700, on sale for 5 bucks. The package looks like the following, and has two rails and 4 little screws (one rail has already been taken out):
Now, I remember I have one of these at the house:
So I'm thinking 'Gee, that rail would mount my flashlight, but I wonder if I can mount the rail to my FAL?' So, I call the house and have Friday make some measurements, and then I grab a tape measure from two aisles away and measure as best I could through the package... looks like one of the rails is an exact match!
So I buy the rail for the 5 bucks, run to the hardware store and pick up a couple of tiny machine screws (#4) that are a wee bit longer than the ones in the package, and also some nuts and some washers. Total cost there was about a dollar or so.
Back at the compound, I mount the rail putting the screws through the two vent holes at the front end of the handguard (this is an StG58 style handguard). Here's inside:
And here's the outside showing the rail:
And here's the light attached:
As you can see, it is placed in the perfect position for thumb activiation of the switch:
