I really like what I have read about the 6.8 SPC round. Had a AR platform in my hands a few weeks ago that someone had built in 6.8 SPC. He wanted $800 for it and was going to buy it. Had a DPMS lower and cannot remember what the upper was but decided against it at the last minute. I would rather have the whole kit be DPMS, Bushmaster, etc.
As for the Remington Bolt Action Sniper Rifle, I would love to have one in .338 Lapua. The video seemed to show some serious recoil for the shooter. Looked like he was getting rocked back pretty good.
