1) has anyone here used the Diamondhead iron sights?
I am doing my wish list for my next build and just saw these in the LEO magazin Guns and Weapons. THought it was a neat concept just not sure of the practicle aspect.

2) Has anyone used the TMS Tactical 3x Magnifier Scope for Red Dot Sight?
I saw this and was wondering how it compares to a vortex or burris magnifier since those seem to be in the mid range for quality. I know it doesn't compare the the likes of Aimpoint and Eotech but not much does that I have seen on the many forums.
