To alleviate the short rail on my scar I also added a stubby VFG at the end of the rail + extend the stock a little.
Beats adding weight with an extended rail there for me.
Edit: If your 6940 weighs anything like my 6940P, it's heavy enough for a 5.56 gun!
whoops. Wrong thread....
Will,
I'll send you an upper receiver if you can disassemble that thing.

Thanx for the generous offer Ken. What upper receiver did you have in mind? The 6940 is a monolithic design, so it's all one piece. Unless I'm misunderstanding the issue/offer, which is likely as I'm no expert on AR platforms. If I added a new upper receiver, I'd need a new barrel and new rail system no?
My hope would be that the barrel in your monolithic upper is not of some crazy proprietary design and can be removed and recycled into a "new" upper of standard design and dimensions. You would then be able to decide on a rail design of your like and choosing. Perhaps a C4 Centurion or similar so as to retain the use of your folding front sight.
