Here's a copy/paste from scout on how I installed an Arca Swiss plate, After this experiment on my .22LR, have since installed these on a few centerfires. Works GREAT!
Anyway, here's parts list & how to:
Parts:
1. Arca Swiss plate. Found
HERE on Amazon Need one, per stock.
2. Long shaft 1/4-20 tripod head screws. Found
HERE on Amazon Need one 2 pk. per stock.
3. Long shaft 1/4-20 T-nuts. Found
HERE on Amazon Need two per stock (comes in a 50 pk.)
OK, here's what the parts look like, assembled, but before install:

To recess T-nuts into stock, you need a 3/4" counterbore bit. Guys who've installed Atlas rails for their bipods are familiar with this bit.
After marking & drilling pilot holes from below, here's a pic of the counterbored holes, with T nuts installed:

You'll want to go easy with the bit, because you're shooting for the bottom of the threaded shaft to be just level with the bottom of the stock.
Here's a pic of the rear T-nut set to good depth, and the top T- nut in need of a tad more relief:

And, plate installed! Those screws can be tightened easily by hand, and snugged with a coin. Plenty of thread to hold the plate tight to the stock:
Best part is, you can remove this Arca Swiss plate in a matter of seconds! So, you don't have to have that thing hangin' under your stock, if ya don't need it...

OK, that was easy!
Now, onto the tripod /ballhead. I'm runnin' a Feisol carbon tripod, with the lower leg sections removed. Did that to save a bit of weight, but also for ease of use. The remaining legs are plenty tall to shoot from a high seated position (think dove stool height)
Ballhead is a Sirui K-10x, but here's the kicker. I swapped out the factory base clamp & installed a SWEET RRS QD throw lever.
FOUND HERE. This part REALLY makes the whole setup jive!

And, viola...a QD interface for any wood / fiberglass stock. All done for a couple bucks, and a bit of time:

Have only shot this a few times, but can already tell that this setup is ROCK solid! Based on this, I'm going to be retro-fitting my varmint rifles with QD plates and using this for both coyote calling, and woodchuck shooting. I'd imagine, it might be equally as useful for a PRS shooter?
That part is up to you. Like I said, just sharing what I came up with & hope it might offer something for the shooters here. That RRS QD clamp is badazz. I can lock the rifle into the tripod, or remove it, in a matter of seconds...
Good shooting!
