Anyone tried one of these? Diamond Series Milled Receiver.

Thanks

Oh forgot tomention they are avail from SOCOM Mfg.  

Thinking about one for an M4 project.

Gotta agree with Troy, but need to add that they are sweet!  I have not built one myself, but have handled a few.  They are one fine piece of work and rock solid.

Yea, I was considering the weight issue and I'm glad my suppositions were confirmed.  I suppose I could get one for my varminter and build the M4 from the BM lower...HMMMM

Other things about the Blue Diamond SOCCOM lowers that make them less than ideal for your project:

1)they have a few semi-sharp/pointy corners on them.  Not the best for rolling in the mud and grime with.

2) The receiver is extra thick in several places and this means that the hammer pin does not come all the way to the outside of the receiver, so that if it walks you can't just jab it back into place with your finger as the pin ends are recessed.

3)the front takedown pin ears are also oversized and I had to grind mine down just a tiny bit to get the end of the Armalite free float tube to clear them.

My copy is from the first 100 run so these issues may have been changed on newer receivers.

The quality on these receivers is very high.

I did my first build on one of the Socom receivers.  It was very easy and the receiver is excellent.  It comes with two set screws to adjust the trigger so that any AR trigger works well in it.  It has an adjustment screw to tighten to fit of the lower to the upper. In a couple of places it uses set screws for springs and the bolt catch pin.  The only thing I had to do on mine was fit the bolt catch to the reciever as it was too tight and did not always hold open the bolt on the last round.  I plan on using the reciever as an action shooting rifle (such as 3 gun matches etc).
