Ordered and received in 3 days. This has to be the nicest mount I have ever used on a Ruger pistol. No ugly rail, no need to by an additional mount to attach to the rail, sits low and looks like part of the gun and not and afterthought. $45 was well worth the price.

Nice looking.
My Lite came with a rail on top. I have yet to put a red dot on it though.

I'll eventually get one when I get a better red dot for my Mk IV 22/45. Right now, I'm using a Sig Romeo 5 and it's doing what it needs to do.

If you'd like to have a little more fun with that Mk IV usncorpsman, throw a Volquartsen Accurizing kit in with a Tandemkross Victory trigger. Perfection as far as I am concerned. The Mk IV 22/45 is the funnest gun I own (for now...planning a Mamba build one day) Everyone that has shot it giggles when they rip 10 rounds off. One day, I'll get a video of brass in the air.
