Both the Barnard S or the P are great value for the dollar.I built on the S in a Shehane Tracker Indian Paint laminate.The "taper" on the S to the tang differs a little (higher,less taper) than a Rem 700 and remains "proud" in a 700 standard inlet.
You can hang a Jewell Trigger off the S if you're seeking BR type tigger break.
They are strong three lug action ,but the shorter throw gives a little harder lift to bolt over a 2 lug.Some BResters might find this disconcerting,but on a 21lb F Class build,it disturbs the rifle in the bags less than a typical LV weight.
They are good to go IMHO .
