I just have the chassis, i didn't get the stock. It has an attachment thread for an ar15 buffer tube. So you can put whatever ar15 style stock you want on there. Right now I'm running a magpul prs stock on there.
I have the LRP in 308 and a Ridge in 6.5 creedmoor. As others have said, the premier action is so much better.
I think for the barrel, the better trigger, and better action, the premier is worth it if you can swing the price difference.
