DoubleStar “Mortar Plate” is a minimalistic AR-15 stock, which clamps on the rear of the buffer tube (receiver extension). It is compatible both with mil-spec and commercial buffer tubes. The “Mortar Plate” is machined from a billet 7075-T6 aluminum and is black anodized. The only adjustment you can make is to increase the length of pull by adding recoil pads. Mortar plate also features five (!) QD sling swivel mounting points. The overall length of this stock is 2″.

The stock features a Picatinny rail section on the bottom portion for mounting a monopod. The latter is a somewhat arguable feature to have on such a compact and lightweight stock. I mean lack of any significant adjustability, small size and light weight make me think it is better to have this stock on an SBR or light weight build rather than on a DMR style gun, but then you have a monopod mounting option. Anyway, maybe there is a demand for it. If you can think about a situation where it can be handy, please let us know in the comments.

The DoubleStar “Mortar Plate” is made in the USA and has an MSRP of $64.99.

In case if you are curious what a real mortar plate is, here is a drawing of US M30 mortar, where you can see the base plate. It allows to firmly mount the mortar on the ground and absorb/transfer the recoil.
