its for a a2 20inch the wife gets what i want every year so any suggestions ? she always go to gun shop by her self and ask a zillon questions they expect her and answers all of them  maybe a ml2 ,gooseneck mount ,rail grabber

The M2 is a superior sight to the ML2.  The military required optical coatings may have something to do with it, or perhaps more careful assembly.  There are few reports of misshapen dots with the M2 (or original M) but lots with the ML2 (and earlier ML).

I also recommend the ARMS #39A2Plus mount rather than Aimpoint Forward Mount.

Will look like this when you're done:

Check with places like SWFA who are probably going to be much less expensive than a local gun shop.

Sounds good so far, but if your wife really gets you what you want ask for an ACOG or better yet a new flattop with an ACOG!  [:D]
