Nope the A7's are all 3 locking lug, pretty sure that is one of the major differences between the T3's.
If anyone is curious as well I can't be more happy than the A7/SS in .300WSM I bought with a Burris 3x9x40 for 1100 out the door! It is a absolute tack driver and shoots ragged holes at 250 all day!
I'm in love with the quality of the action, the barrel and all the components other than the stock. It's not total tupperware, however I'd love to slap it in something nice. I phoned Bell & Carlson and they said they are in the process of making some new moulds for Sakos. The lady wasn't sure if they were making any for the A7 specifically though.
