What kind/brand optics are you using if any at all. Please post your likes and dislikes about it.

I have a special run they did a couple years back called an "Eclipse".  5.5" barrel, came with solid black front sight and adjustable rear.  Put a HI-Viz fiber optic on the front.  Love the ease of switching colored pipes, especially helpful for indoors vs outdoors (green better indoors, red outdoors I've found).  I also bought a rail for the top and have played around with a $50 Sightmark red dot reflex site which was ok, wouldn't call it high end by any means.  Like the ability to play with changing reticles and the price was good.

I have the Eclipse as well.

 

I have a C-More Railway on a T/S mount. It works great. The only issue is getting used to acquiring the dot on the C-More, but that is more of a training issue than anything else. It's a great set up for steel (primary use) and for plinking.
