Sights are Tech Sights SKS. You can buy them online all over for about
$100 CAD. Optics Camp is one US company that ships to Canada. Side note:
you have to remove the takedown latch to install it. I just filed the nub off and removed it. If I ever want it back to factory I'll just drill a hole through it, slide it back into the receiver and press a roll pin into the hole and trim it to length. Back to original! You also must remove the factory rear sight and leaf spring so you can get a proper view to the front post as the Tech Sight sits quite low which is ideal.
Front post is a precision one. I think you have to buy a set of 7 of them now on
Amazon.ca for $50 free shipping! Totally worth it. They sell them individual in the USA for $7 but I could not find a company that ships to Canada aside from buying the pack of 7 different ones for $50. That's still a deal though!
The butt pad is called UTG Deluxe. They have 1" and 2". The 1" was perfect for me. I'm 5'9" and all #### and ribs and it was a huge improvement.
It was $20 shipped off Amazon.ca You have to remove the steel plate and spring hatch but it used the original screws. It's very well made, great grip and perfect LOP improvement.
I strongly recommend any/all SKS owners to study/learn/understand the trigger mechanism and do a home trigger job. It's about a 4 out of 10 difficulty on the white trash home gun tinkerer scale.
So basically $170 for front/rear sight and butt pad to get it where it needs to be from a $200 rifle and the free home trigger job with a bit of study and educating yourself
