Need help picking M4 red/green dot

[2shotjoe]

Anything up to 9x that doesn't hurt the pocket much. I am unsure of all these brands and over priced products. I rather buy another gun if over 400+


I own these 2 scopes, should i just use these and find a high scope rings? Scope rings I have are super low profile.
