    The actual M231 fires from the open bolt. Do
    you know if it uses the Atchisson type OB FCG or some specialized parts that do not drop in?

    DPMS used to make a M231 wire stock. I sold one a while back. They are discontinued but do come up every now and then.

    I wonder if there are any prints for the gas block out there. It would be simple to machine. The handguard looks like plastic so it would have to be molded or faked out of aluminum.

    I dont know about easy to machine, maybe with a CNC machine but using an conventional lathe..... the radius on the thread itself wouldnt be much fun.

    I had to do some research after reading your post, because the prototypes I saw at Aberdeen Play Ground in 1973 were closed bolt, but you are right the production gun was open bolt.

    It was designed to screw into the firing port mount of the Bradley Fighting Vehicle.

    There are repro handguards for sale on Gunbroker. The DPMS M231 stock is ok, but when the stock is retracted, the buffer tube sticks out farther than the stock. Original M231s used a tube & buffer shorter than a carbine buffer.

    For simplicity's sake I would just cut a square thread and hand finish it. Can't tell if it's tapered though.

    It would be great if you actually posted a link along with that price.

    you planning on using an ar15 buffer and spring? it doesn't look like the airsoft one will fit the spring. if you're using it for a .22 build it might work.

    also you might want to see if the threads are for an ar15 receivers. some airsoft parts won't just bolt on.

    keep us posted.
