Hi Guys, I am running a Colt M4 Le6920 currently with an EO Tech holographic sight. I am interested in shooting out to 300 yards or so at the most. I shoot for fun and competitively among friends. I would love to purchase a Trijicon Acog 3x or 4x but I do not have that kind of money right now. I am interested in the following sights, please let me know what you think or if you have a suggestion for me. I am looking for a fixed sight (i think). 1: Burris AR-536 :http://www.cheaperthandirt.com/product/2-BU300210 2: Burris AR-332 :http://www.cheaperthandirt.com/product/6-0924452 I am new to this and looking for input. Thank you.
