I looked at one a few years back when WalMart had some on their shelves. It had a neat looking design, and if I'm right, it was one of the lighter weight options. I ended up with a Daniel Defense that cost like $55 more in the end, and probably just because I over analyzed it all for a week before buying an that just happened to be where the wheel stopped spinning at. As for the UTG Pro, I have one in my bedroom floor I took off my cousin's gun. Its very solid, but its quite a bit heavier than most of the others. Check out the Midwest Industries drop in as well. Very lightweight, and like the newer UTG, it has the bridge over the top of the delta ring that bumps up against the pic rail on the upper. Also has quick detach sling points in it as well I think.
