Gentlemen, have a FNX for about a month and love it. Never used a reflex red dot but want to try one (inexpensively) on my FNX Tactical. If i like it i will upgrade but do not wasnt to spend 500 to learn. My questions are: 1.what would you buy with a 6moa dot. 2. What sight fits on the plates that come with the gun? I have found 2 inexpensive sights but theyou require me to buy or make another plate that is about $45. Thanks in advance for your help.
