I am an avid pistol and competition clays shooter, however I felt I needed to find out what the AR hype was all about. Had my AR-15 for about 2 weeks now and have put about 2,000 rounds through it. I'm an avid fan of iron sights and have the new Magpul MBUS PRO 2 and love them. However, my dominate eye is weak and hard to pickup front sight. I alway paint my iron sights on my over/under and pistols. Has anyone every painted their Iron Sight posts or do they have drop in posts I can screw in to replace OEM post on the front sight?? Thanks for any assistance guys! Really excited to be a beginner again and learn all about this amazing weapons system!
