I can't get past the fact that they are plastic. (Magpul)
Have you looked at Yankee Hill Machine?

I'm thinking about getting the QDS sights. I saw some with a Spikes Tactical logo on them. They would look great with my lower!
I am also leaning towards the Bushnell holo for my build.
If you want to get a cheaper red dot that still works good, try a Vortex Strikefire. I have had one for about 9 months and it works great! It has always held zero and it is still on its original batteries thanks to the auto-off feature. The dot very bright and the optic is easy to see through. Looks pretty good, too.
4 moa red or green dot with night vision mode, flip up lens caps, and 1/2 moa adjustments. It also comes with a 2x doubler! I think I paid $150 for it. Chicken feed when talking about optics.
