Had so much potential - Falke CS 4x20mm Ballistic Reticle Prismatic Red Dot Sight

I had seen this before, and kicked it around a lot, but held off because of its Chinese origin/price ratio. It came up for sale on Dvor for ~$150 and I bit the bullet. I had relatively low expectations, but when it arrived and I got it mounted,, I was impressed with initial build quality and clarity. There was 1 fatal flaw in the design that I had failed to notice before mounting. There is NO locking lug in the base of the mount to prevent forward/backward movement between picatinny slots. There is only the screw/bolt that makes the QD system work and it properly fit on any rifle I tried it on. There was no side to side movement, but there was front/back movement between all platforms tried. This little guy had so much potential, but an optic that moves constantly isn't good for ANYTHING. I returned it.

-optic is designed by Germany, made in China and supposedly inspected again in Germany(according to a website I had found about Falke optics.
