I bought a 6.8 last week from AJI Sporting Goods in Phoenix. They have another XCR shipment coming in this week but I think they are all 5.56 and a 7.63X39 that is already spoken for. Give them a call at (480) 984-8616. Great guys, great prices.
I've only put about 50 rounds through it sighting in but I like it a lot. May have to start reloading if the military doesn't adopt this round, other wise have to get used to paying a buck a round! If Alex perfects the 6.5 it will possibly be cheaper to feed as Wolf Gold goes for about $12.95/box. I didn't think I had the time to wait for it considering the election results. By all reports the 6.8 and 6.5 are nearly the same out to 300 yards, then the 6.5 excels.
