SCAR is even worse then the XM8 for being a tupperware gun...
reference for that comment?
I like my guns to look like guns...not plastic toys...
So, did you pick up that M&P9 yet?
So if your into this thread you should get the Barrett 6.8, FN-SCAR, or HK-416 all of which cost well over $2,000 and out perfom the XM8.
Actually, the 6.8 uppers will fit and function with the AR lowers, even using the existing mags. So, for about $400 - $500 depending on length and manufacturer, you can get a 6.8 upper and use 1 lower for both 5.56 and 6.8.
Myself, I'm working to save and build an 18" rifle in 6.8. If the $$ happens to be there, I might build a 6.5 Grendel also. Now THAT'S a bada$$ round.
What's the best price you've seen for 6.5G complete uppers? I really want to get one, but I'll be a while saving yet.
