Aimpoint Comp M2 with Wilcox mount

I really didn't need one of these, but it was a good deal so I grabbed it.  The bonus was it came with a pretty rare item that's not commonly found in Canada - the Wilcox mount.  It's rare, but then again, the demand for it is also pretty rare.  If you were building a Mk18 mod 0 clone, you might be looking for one of these, but other than that, there's probably not a lot of demand for one of these.

The Comp M2 is a 4 MOA dot with a 10,000 hour batter life (1 year of continuous use).

The PRO on top, and the Comp M2 below.  They look virtually identical.

Compared to the Aimpoint PRO, I'm not really sure why anyone would buy a brand new Comp M2 for full retail (though I think it's discontinued).  The PRO's MSRP is generally less than the Comp M2.  The PRO has a 2MOA dot versus the Comp M2's 4MOA dot.  The PRO comes with flip caps, as well as a QD mount that's adjustable for height with a removable spacer.  The battery life on the PRO is longer by two years of continuous use.  

I guess the only reason I picked this up was because it was pretty cheap.
