Anybody use the SI Defense upper receiver, barrel, parts?

They have about everything you need to put together an upper at a reasonalble price.  Just needed some input to convince me. Thanks!

survivalshop (member on here) has a couple of them, I think - I know he's got one for sure.  He'll be along pretty soon and chime in.  <thumbsup>

I got a SI Defence ,gen. II billet upper for one of my 308's & I like it .

Not sure if I have a use for there side rail on the upper ,but it is made well . They have a gen. III with out the side rail & it has a forward assist.

I would buy another . I just wish they had made the gen. III when I was looking for an upper , I would have bought it just because of the FA.

I am going to go with their lightest one they make.  Says it 15% lighter than the lightest DPMS.  I am going to try and build the lightes possible gun I can.  I am trying to figure what barrel I am going to use.  Maybe just stay with SI Defense barrel. It has sort of a M4 profile to it, and they have taken all material off except where it is needed, ie. the gas block point and where the threads are.  Anyone have any suggestions on something better?  I am also going with the DD 12 LITE  Handguard, as I also want the gas block covered. Scope and mount and no backup sites, as this is going to be my coyote gun at times when I don't want to shoot the AR15.  But, still going to try out the .50 Cal on coyote sometime. Thanks for any help or suggestion given.
