I was at a shop a couple days ago and saw or heard of these for the first time. The rifle appears to be pretty well built. I was making my rounds at the gun shops, and three out of five of them had these in stock. All were priced the same at $1199.
I think these should be $999 tops. $850 to $950 once the newness wears off.
SA seems to be claiming the M16 style bolt carrier group, the accu-tite tensioning system, and probably the M4 feed ramps, as upgrades or "innovations" that make the rifle better than the original A2 style rifles sold on the civilian market.
