I'm not sure if I need the taller height iron sight option. The current sights are AmeriGlo's and the front sight reads H3 LK while the rear sight reads H3LA

FN 510 MOS has a Red Dot on it. I also just put high sights because I wasn’t sure, in the past have ordered a holster from BPT that didnt work for me, so just wanted to specify here. Thank you
