I’ve had a Ruger 10/22 Takedown that I bought not long after they started making them. The factory sights were sad to say the least and couldn’t be adjusted enough to correct the elevation. It shot 3 inches high at 25 yards with CCI standard velocity and worse than that with Mini mags. Never could get a scope I liked set up on it and that kinda defeated the purpose of the takedown anyway. It sat in the safe for a long time until recently when I ran across “Tech Sights” for a 10/22 that had good reviews, and a good price.
So, I ordered a set and got them installed. They seemed pretty nice and are made from aluminum. Took it to the range today and got them zeroed with less than 15 rounds shooting 3 shot groups. Now I can shoot 1 inch groups or better at 25 yards with irons, which is good for my old eyes and shaking hands. It has a second aperture that flips up that I’m thinking will work at 50 yards (the apertures are supposed to be for 50 and 100 yards but I can’t see that good at 100 any more.
I would recommend them if someone needs a sight upgrade. They look like the picture below:
