I've got a front sight tool that goes on my key ring, that way I never forget to bring it with me.Been using M 16 type rifles since 1966 and never had a sight tool until I picked up an AR tool kit at a gun show and it had two front sight tools,one four prong and one five prong, can never remember to take them with me to the range and still end up using a bullet tip. I can still use my iron sights but my eyes sure aren't as good as they used to be!
