Magpul is branching out more into precision rifles. Now they are coming out with a stock chassis for Remington 700 short action rifles. The stock is very similar to their SGA shotgun stock. It looks like it uses the same length of pull spacers and cheek risers.
It is unclear what magazine they will be using or the price of the stock but I am sure we will find out at SHOT SHOW 2015 next week.
You can see the stock below and it appears that it is a 3D printed prototype.
