The Mortar Plate was designed for those who need an entry-type stock for their rifles. Made to fit both the commercial and military spec receiver extension tubes, the Mortar Plate is machined from rock-solid billet aluminum then Type III hard coat anodized. The Mortar Plate offers a small section of picatinny rail on the base for mounting monopods. There are five Quick-Detach Sling Swivel pockets for a variety of sling and carry styles. To extend the length of pull, add the .5" or 1" Recoil Pad.
