I was picking up my newest partner for my ARs, a Brand spankin new H&K USP .40 Compact LEM. Perfect carry weapon BTW. AndI have always been drooling over the rare weapons that Colt has let go of and put up for sale.  In addition to the 100% camo Pre-Ban Colt Prototype Camo AR15, Green Label, Blue Label, and new PreBan Colt CAR Tactical Carbine that only 100 were released. They have a Preban Colt with the LMG upper.  It is one of the baddest AR15s I have seen.  Basically looks like a SAW.  Has anyone seen these? Anyone have one?  What is a decent price for these?  They are asking around $2500 for it.
