I'd put one of the lower end Geissele 2 stage triggers in it.
308 is a little harder to light than .223.
I've had a couple AR10's, from 6.5 Creedmoor to 308 win. Have never had any issues with the triggers I suggested, or a CMC single stage, or Geissele SSAE, except the SSAE was too light for the 308 win recoil. On occasion I'd get unexpected double taps with that Armalite AR10T. Pulled that trigger out, and use it in my iron sight Noveske. The Geissele G2S would also work well in the AR10, which is what I'm assuming you mean by "lower end" model. Personally, it would come down to price:
1. RRA 2 stage varmint match: $93.95 (3.5 pound pull)
2. Larue MBT2S: $115.00 (4.5 pound pull)
3. Geissele G2S: $170.00 (4.5 pound pull)
Looking at those prices, and the lighter pull weight of the RRA, the choice is a "no brainer".
