The Magpul won't be in the same category frankly. It's not as customizable and any traditional stock even with a chassis system usually needs bedding to perform at an optimal unlike an aluminum chassis such a this. I know a bit about the development and there will be a lot of options coming after the initial release. They also took this chassis out for testing with a well known competition shooter in the practical rifle long range community who is helping them to further improve it. Is it perfect out of the gate? No... But it will only get better as they move towards production and get feedback from guys who shoot competitively and have employed dozens of different stock systems.
