Scoping the FAL

Glad I saw this. I was about to order DSA para cover for myself. Now I'll make sure it's installed right. Thanks.

Old style US Optics SN-4 scope, 1-4 power, 308 BDC dial, circle dot reticle, low mounted in Leupold QD rings on DSA mount. Rear of mount has first lug milled down for clearance. Compact and handy.

Well, I've played withy 686+'s idea and this is the result of my proof-of-concept.
Within the context of having a non-removable red dot, I am pleased.


The issue of the screw head breaking through is real, you can see a couple spots where it just creases the scope rail side. I dunnno - why does this matter? It already has 10 exposed screws, perhaps just embrace it.

I went with 8mm M3x.5 and countersunk the v-neck flat head screws until 3 threads poked through. The original is around 4-4.5 threads, and I didn't want the screw to bottom out on the sight.

I used a 6mm solid pin to take the shear off the screws.

I made two mounting locations. If I were to do it again, I'd make the space between the two mounting points the same as the hole spacing, which would give 3 point. Don't know why I didn't think of that before.

I used the original base to align the holes, before machining off the rails. I installed the shear pin last. This meant that subtle alignment issues came into play as the stacking of tolerances winded up making the screw graze the side of its hole. Since I don't know the strength of the the screw holes in the scope itself, and didn't want to strip anything, I enlarged the holes from 1/8" to 3/16". If I were to do it again, I'd set the shear posts first, and then use them to set the screw hole positions.

Sorry, but my photo skills aren't good enough to get the dot in focus along with the front and rear sight.

It is a bottom 1/3 cowitness. Would be even closer on the taller Agy/Izzy sights.

kudos Mark......I see a niche in this market...kudos......

sorry to hijack ish but with removal of rat tail can the para scope mount be used on a fixed stock.

i am wondering if the change would be a benefit or deficit. with the change the rifle should work even if the stock is smashed or messed up. i heard the nut in the stock may rust, or the spring may rust.

i hate typing. what i mean is, field use taking buttstock tool out to fix the problem takes more time. vs popping open the action and replacing the spring and guide rod, in seconds.

does my thinking make sense. or have i reinvented the wheel over complicated life.

I consider the para return spring assembly to be less reliable than the standards stock. Not that either are unreliable, but stacking 3 springs on top of each other is more complicated than one spring. I think the one long spring is simpler and therefore at least theoretically more reliable. I have built a standard stock model using the para spring, as that allowed me to cut a wood stock short.

But the bolt carrier for the para is different than a standard so that the 3 springs and guide can run inside it. You cn remove the spring guide from a para top cover and use it on a standard, but you cannot use a standard bolt carrier in a para.
