Not on a Mini 14 but on my Bushmaster 16" M4 ORC I am using a Bushnell Elite 3200 1.5x4.5x32mm Fire Fly Rifle Scope. I use this scope for work also so wanted a large field of view and a reticle I could illuminate. The Fire Fly Reticle is not electronic but rather by shining a flashlight in the eye piece of the scope the crosshairs glow a soft green. I do not get GLARE from the Fire Fly Reticle in low light like I have experienced with Electronic Dot Sights.
On my Bushmaster 16" M4 ORC .223 wit hthe Bushnell on 4.5x I can get sub 1" groups from the bench at 100 yards, plus I have shot Coyotes out close to 300 yards with it so I see no need for more magnification. I also really like the large field of view on 1.5x for when things are close and personal.
Just relating what I use and what I use it for. Others opinions and uses may vary.
Good luck
Larry
