SKS Modifications & Additions of Open and Aperture sights

Very nice!

Can you show some pics of what the sight picture looks like and more pics of your invention please?
 
A very professional looking job. ;) well done.

I got it done in my garage with a small piece of 1/8" steel plate, a drill press, zipcut and a welder. Cut the open sight off the rear sight leaf and weld the new piece in place. I went with a fillet weld for strength. Aperture size is 3/16". Some of the front sight hood was in my FOV so I cut it down much like an AK. I chucked the front sight up in the drill press and used a file and emery cloth to turn it down to about .050" or so from IIRC .069" as it came from the factory. Reblue the parts and you're off to the races.
 
Regarding galvanic dissimiliar metal reation using aluminium on steel, yep could happen. Both metals are treated/painted and this could also create a capacitive reaction as well. However this will happen with any accessory you put on your rifle so I wouldn't really worry about it. I like the rear mid sight "ghost ring" too but I tried the Williams version and the apeture that far down didn't do anything for me but it would be good for close up snap shooting. The rear disk on the my setup uses the target apeture (or you could put in the larger holes as well). I have switched back to the standard rear notch sight and am finding a have to us a scope now anyways for vision correction issues. The mounting plate is a weaver convert a mount but I have seen people use bed rail for that too. I'd like to see someone put an enfield style ladder sight on the SKS but it would be tricky especially to keep it foldable for battle sight operation.
 
Fat Tony,
The aperture is the same size as an A2 large aperture, with it mounted further forward it shrunk the FOV to about the same dia. as the front sight hood appears when sighting down the rifle. I intended it as a do-all for trying to be accurate (snicker), plinking and trying to go fast (like driving an old truck on a racecourse meant for cars) and it did those things pretty well. As beermaker said, the sight radius is still short. A peep mounted near the rear of the action will work best. I pondered some ideas for such but couldn't think of much that was free and available to me on a saturday evening. I also wanted to retain the original sight for its looks and range graduations. Its almost stock, but smarter than your average bear ;)
As for steel on aluminum corrosion, ever pull the aluminum crossmembers out of the steel frame of a Kenworth C5 chassis after decades of use in the oil patch? :D Ain't much left where the two parts meet. The aluminum by far gets the worst of it.
 
Please feel free to post what you have done with your open or aperture sights in this thread. It will be nice to have all of the ideas in one place.


This is a simple aperture sight that can be built with hand tools. It has both elevation and windage adjustment. The sight is 1-1/2" x 1/2" x 1/8" and there is about 3/8" of travel in the slots. The upper slot is twice as wide as the lower slot. The lower slot is a snug fit on the 6x40 screw. The holes in the dust cover are 6x40 thread and 1/2" apart. The lower hole needs to be on center with the retaining pin hole.



Here is one way of adding a high quality aperture sight that will not effect your regular cleaning and maintenance. (Like a Tech-Sight would) This will probable require some machine work but it could be done with hand tools by a skilled craftsman. The dust cover is drilled and taped in the same way as above. A piece of aluminium shaft with the correct diameter for the radius on your sight is all you need to get started. The rest is self evident from the photos. Just make sure that the mount is low enough. Just about any Redfield or Williams sight could be used. This one I got many years ago on Ebay.

That trigger stop looks great. Almost like it was supposed to be there. It's a mod I have been wanting to do, but have been holding off because I am reluctant to drill. I have been avoiding the permanent modifications. That might just change my mind.
 
It toying with the idea for a while then decided it's a $250 gun, why not lol

I also stripped the factory stock and re shaped it to fit my hand better then finished it in OD green.

I have a nice sling that needs to be installed, waiting on mags and tech sights before I post a pic ;)
 
I actually made that out if a sling quick disconnect stud pin, threaded the trigger ring then threaded the stud fitted it and rounded the end for a nice smooth contact area. Red lock tite and tightened it up

It makes such a huge difference in the length of pull follow up shots are so much faster, I will be stoning the contact points and polishing it to lighten trigger pull this week
 
I found an extra spike bayonet that I cut. This just happens to fit a bi-pod that I use occasionally. No change in recoil but a lot less bolt slap.

Very nice.

Whats up with your bayonet? Did you just take the blade off and leave the rest there, or did you add something to it?

With the hole you drilled in the gas tube, do you notice any difference in recoil?
 
This is a peep off a Lee Enfield #4 "L" sight. Cut a slot in the cover and brazed the sight in place. Zeroed the rifle with the front sight. the 1/4" x 20 bolt is threaded in place. Keeps the cover solid.
