I have one in .308 and damn do I love it. When I sighted it in with Federal Powershock 150gr's @ 100 yrds my best group was 1/2" and the worst was a little over 3/4". Everything else fell in between. Still need to tinker with reloads as I got it not long before hunting season and didn't have a lot of time. Last I shot it, I was grouping under 2" @ 200 yrds.
The trigger is absolutely beautiful. Crisp and light.
Right now it has a Limbsaver buttpad on it as I like a little more length of pull and the stock buttpad was definitely rock-like when it was cold. The rubber is less than 1/4" thick with plastic making up the rest. I also filled in the buttstock with spray-in insulation foam which makes it not sound so hollow when walking through brush. It seems to make it more solid too. I also have a Harris bipod installed. The only other thing I changed was the sling swivels as the stock set seemed to fit loosely in the studs and rattled constantly when being carried.
As for optics I have a Leupold VX-II 3-9x40 in a pair of Leupold Weaver QD rings. You are right that bases come with the rifle. I carried it around all last season moose hunting on foot and it being such a light rifle was great.
All in all I am very happy with the rifle and have no hesitation recommending the A7 or its cousin, the Tikka.
