THE IMAGE ABOVE IS A PAID ADVERTISEMENT Started by grinding down the right side. Layering into it with a stone cutting disk. Then got it closer and smoother with a grinding tip, and finished with some fine sand paper. 
Did the inside of the rear ring, starting with a cutting drill tip, shaping the hole, and finishing with a small sanding tip to polish it off. 
Taped the inside of the rings in prep for painting. 
Three layers of black temp paint, then three more of tan camo paint 
Pulled the tape off after 30 min, and really had to kick my self off the project. I have a bad tendency to mess with paint way to soon. 
A few hours later, I was in the sink wet sanding with 900 grit paper. Just long nuf to smooth out the finish. 
Although I could have done one more layer, I was really happy with it as is, and didn't want to make this to long of a project. 
Drying everything off after, hit it with a heat gun for about 15 min on top of air drying. 
All back together, re greasing the DQ levers, and lock tight on the QD ends as well as the rings 
Lining everything up, and tighten it all down. All done!

So, after all that, I am having trouble finding the part where you tell us how much you decreased the weight.

Beyond what you did, I would bore a hole in the front ring, and then I would do a one inch slot in the channel between the rings, and then I would bore a half inch slot in the channel after the aft ring.
This thing is WAY overbuilt, and easily a 1/3 more weight than it needs to be. |

You need a mill. These mounts are definately on the heavy side and could use some milling. I think you could almost cut the mounts weight in half if you had a mill to do it with.

Very cool.
I second the ideas of another hole in the front ring, and the two channels in the base. I wish I had the skill and a mill to do something like this to mine. Very well done. |

Even if the weight difference doesn't end up being that great, that is some mad Dremel work!
An inspiration to all of us!  |

This thing is WAY overbuilt, and easily a 1/3 more weight than it needs to be. Because of this weak point in the mount from the factory cut, I really have no interest in milling out the center of the mount. Its very silly to me as to why they did the mount this way. 
Thanks for all the Dremel tool complements, lol . Here is a link to my write up on making my A2 front post low pro with the Dremel. http://www.ar15.com/forums/t_3_4/571980_A2_low_pro_gas_block_challenge__pics__installing_a_Troy_Alpha_11.html Sorry I don't have a before and after with the mount on the scale. Mine was acting up and did not give me a consistent reading, |
