The Evoke is a Remington 700 LA footprint, regardless of SA or LA cartridge. It should be compatible with any LA footprint stock/chassis out there. The difference between the factory SA and LA is just the location of the bolt stop, and a modified bottom metal assembly for either your LA or SA magazines. Not 100% sure on the factory bottom metal compatibility with all aftermarket stocks/chassis, so just be aware that it could require some tweaking if you need to use it. That and if you try and drop a SA evoke in a LA chassis with an integrated magwell/bottom metal, you will need to use modified magazines to feed a SA cartridge.
