The MK1 Bullpup Chassis is made by MK Machining and allows you to shorten any Remington 700 pattern rifle by nearly a foot without cutting precious inches off of the barrel. There are several reasons this can be advantageous which include the ability to add a suppressor without the gun becoming unreasonably long, putting the weight further back toward the shoulder, making the gun easier to shoot unsupported and shortening the gun to be easier to store and carry.
