This is a yet unnamed prototype stock for an ar15 inspired by the zenitco PKM stock.
The addition of a rear grip surface makes shooting a light machinegun from a bipod or tripod more ergonomic.
The stock mounts over a standard rifle buffer and is retained by the same standard 1/4-28" bolt as a standard stock.
The adjustable cheek riser needs two countersink M5 bolts 30mm in length overall, and matching nuts.
The rear portion of the stock is adjustable up and down and needs the same 30mm bolts and nuts, and at least two should be used.
The buttplate is held on with three countersink m5 bolts 20mm oal and matching nuts.
A milspec M4 Stock rubber slip over buttpad needs to be installed over the buttplate.
An ar15 grip attaches to the front stock half with the standard 1/4-28 bolt and washer.
There is a slot under the buffer tube in the front half for looping a sling around.
This stock is so far untested.
