I am wanting to make a stock like this without losing an arm and a leg. I know alot of people will say they are worth it just do it. But right now I just do not have the cash.
anyone have a how to they would share?

Yeah, it is easy and simple too.
A company called Mako used to make an AR15 pistol grip/stock adapter for the Mossberg 500 and Remington 870 shotguns. You can find them on Ebay still. I used the mossy 500 version.
You can cut the grip and butt off an M1A stock, drill a hole and dremel a "C" shaped cut into the stock. Fill the cut with epoxy to make a perfect fit and mate up the adapter. You'll need a longer bolt and a nut to secure the adapter to the M14 stock. After it all sets, it is quite solid. Then you can mount whatever AR15 furniture you like.
A few things to note with this project: if you're serious about trying it, jump on the Mako adapter as soon as you find one. They are discontinued.
Unless you counter sink the nut on the inside of the stock, you have to take care to make sure the bolt won't hit it on its rearward travel.
The M14 action sits slightly off-center in the stock (right side is thicker than the left - for the now non-existant selector switch). You need to drill the hole off center to compensate.
Take care to mount the adapter such that the trigger guard can still pivot out for breaking the gun down. Alternatively, you can modify the adapter a bit as well.
It is super easy and it all becomes apparent as soon as you have the parts in your hands.
