I bought the very first red-dot sight I ever encountered.
An Aimpoint 1000.
I put it on my Mini-14 in a B-Square mount.
It lived on the never fired Bushmaster M-17S FuzzyGeff owned for a while.
It resided on Marv's first AR for a brief period as well.
It's still in service on The Lovely Harvey's 10/22.
I did not have the five hands needed to get a good picture of the dot...
Every once and a while I get asked why I say you should buy once, cry once: this is it. It's been around for about 23 years and it still works. The only other electronic item I still have from around this age is my boom-box that sits in the garage. I am not certain that it still works... Update: It's still a radio, the CD player is kaput. Dunno about the cassette players, they still spin but I don't have any tapes left to put in them.
