Warpaper purchased a brand new RMR replica red dot sight which comes with markings which they installed on a Tokyo Marui Glock that is kitted with the RMR kit. Looks like it's poorly made as the lens fell off after 10 shots. They get another RMR repluca made in Taiwan and the lens still are still on the sight even after 80 shots. The cons they find is that it doesn't have markings and red dot offset caused by the blowback action.

Looks like you have to spend more for a better RMR sight, say like, the real thing?
