Funny, I believe he's having the pro shop do it. This man is a great customer but I told him he had to raise the front sight, get a taller one, I lost out. I'm not in any way boning on my customer, I'm just wanting to make sure I'm not completely crazy. I even test fired a carbine today and imagined the front sight being taller while shooting, my POI when down just like I thought it should.
