Barret XM107 other than price? Which differs by about $2500 They have all the same features, I think . . .
The M107 seems to have the long accessory rail across the top of the receiver & I'm not sure if the Norwegian demo gun does.
It seems that the XM107 is in high demand, but the NG Demo is also few and far between.
Why is it that the price differs so much?

And my most important question is . . . which one is better and why?

Thanks . . . db
