I'm not sure if this will be relevant to the Alphahawk's page or not, but I think there are two variants. The difference is in the front sight.

So, this is a picture from Blasterhub. It shows a three-part sight - a short vertical post at the absolute front, a ring just behind, and a much larger vertical post a few inches behind the ring. 

And this is the one in my house. It is completely missing the the large rear vertical post.

At first I thought mine could have simply been broken. But it is very clearly molded with a smooth surface in that location. So then I thought maybe the Blasterhub version was just a prototype, but then I saw another one on eBay that looks identical (all three sight components). 

I thought this might be useful information for the blaster's official page, whenever those get updated. 

Personally, I wish mine had that third component. The ring and front post are too close together, and too far forward on the blaster to be useful on their own. I ended up slapping my Deluxe Stormtrooper Blaster's sight onto the Alphahawk's tactical rail - a major improvement. Now I'm consistently grouping five Alphastrike rounds onto a letter-sized piece of paper at a range of about 16'.
