i have a troy fixed rear sight for my wife's rifle and mine wears daniel defense fixed rear sight.
i did use magul flippers, but i prefer the fixed rear sights with the A2FSB i have
magpul PRO's are the cheaper alternative to the Troy Battle sights
i dont do regular golf anymore. i kept losing money having to replace my clubs. so i switched over to disc golf instead. i find it less stressful, and a whoooooooooole lot cheaper (ish....)
