Re: AR-15 Run and Gun / 3 Gun sight sugestions
I ran an eotech for a couple of years shooting two gun matches, and then I tried a 3.5 ACOG for a few months. The last two years I've been running some HK Style Troys on my DPMS 3G1. I mounted the front sight on the gas block (extra sight radius), the rifle length gas system, and spikes Tungsten buffer make it easy to stay on target. I purchased a Burris Tac 30 a couple of months ago and at first it seemed like I was shooting slower at distance but the timer proved otherwise, even the splits and the close work was just as fast as my eotech times.
I will share some of the negative issues that I have encountered with the various sights that I have employed. The battery terminals on the eotech have broken (still works but the terminals are loose). The 3.5 ACOG works great, but slows you down when shooting in unconventional positions where you cannot shoot both eyes open such as the VTAC 9 Hole barricade or any slit in a barricade. Plus I felt like I really had to have a stable shooting platform (grip/stance) in order to manage the recoil/faster follow up shots with the fixed 3.5 magnification. Can’t complain about the iron sights, haven’t encountered any issues although I did install a tritium front sight just because I had one sitting in the safe. I haven’t shot enough matches with the Tac 30, but the first match that I ran both the iron gun and optic class I shaved my overall times with the optic by more than twenty seconds overall. The Tac 30 allowed me to experiment with a variable without breaking the bank.
For now I am going to stick primarily with the iron class, I figure if you can master irons it should only make you that much faster with a tradition red dot. Although those Troys cost all most as much as the Tac 30.
