Re: Brown Precision Stock
If its a std hunting style stock, classic design, it will only be a drop in for the factory rem bbls. You can inlet them, but if the bbl is larger as the #4 is, you will go through the glass cloth in the forarm area. If you do that its best to replace the cloth and bed the entire action and barrel. Wrap some tape around the barrel so you will end up with a floated barrel.
Brown Precision was my stock of choice 20 years ago.
