Whoever turned me on to the Blitzkrieg front sight for my Benelli M4 (I think I saw it in the Beretta 1301 thread), great job.
I finally found the perfect replacement for my old dimming XS 24/7 Big Dot.
The diamond makes for a more precise daytime slug sight, the tritium is great for low light and my AVA mounted Surefire charges the Luminova with just a 2 or 3 second blast (like you would normally use a WML), the bright yellow/white diamond is also really easy to see while the Surefire is on full blast.
Here's a pic of the sight after about a 3 second blast from the AVA mounted Surefire P2X Fury.
