I have a Sig 556 SWAT that I'd like to improve upon. It came with a really inexpensive Red Dot from Sig, but even on it's brightest setting it's almost impossible to see in any outdoor condition short of night or heavy cloud cover.
I see lots of people happy with the Aimpoint / Eotech's in particular. So these are two brands that I've been reading up on, but am still open to ideas. The one thing I'm interested in possibly adding is a 3x magnifier that both brands offer. My reasoning being that I'd like to extend the useful range over what my naked eye can deliver. I like the idea that both offer mounts allowing you to rotate the magnifier out of the way and allow me to just use the red dot.
Any suggestion / advice on the brand (all are bloody pricey!), usefulness of the magnifier would be much appreciated.
