For factory rifles, there's a reason Tikka and Bergara tend to be the most common recommendations. The Bergara HMR factory adjustable stock is honestly gtg for most shooters. It really doesn't need anything and I recommend people that go with that option to shoot it as is until they shoot the barrel out and then start upgrading. With the Tikkas, they're excellent rifles but I disagree with the recommendation of the Tac A1. It's a good chassis, but for less money, I could buy a standard T3x CTR and a KRG bravo and be able to use standard AICS pattern magazines.
If you wanted semi-custom, I'd recommend the Seekins Havak HIT or Bravo, depending on your budget. Or if you're wanting something a little more versatile i.e lighter, the hunter models are excellent lightweight rifles that are still capable of precision shooting. Too light to shoot PRS with but I'm guessing you're not going down that path with 308. You could but there's better calibers.
Beyond that, a lot of custom manufacturers offer preset packages to choose from which are cheaper than a full custom.
My choice personally though would be to buy a custom action that I liked the features of the best (Terminus, ARC, Zermatt etc), as all the popular actions have pre-fits available from multiple shops, and buy the chassis of my choice.
