I'm curious what the opinions are here on the PFOA forum. XCR, AK, FAL, SIG556, AR-piston, Kel-Tec, wait for the SCAR. What is your preference and why?

Also, what caliber would you prefer? I love what I've read about the 6.5 Grendel but I don't want to deal with a DI AR-15 and no other formats are offering 6.5 Grendel at the moment...that I know of.

(This thread is not intended to cause an argument that DI is good or bad so lets just make it a non-issue. DI AR-15's do not exist on this thread.)
