Here is one for you I need some help on,

I MAY be getting a DSA FAL receiver from a Falfiles member that has been ban or cutoff sawed in half by his son-WTF!!!!!! ANy way I am thinking it could be rewelded back to gether using the dust cover as an alignment tool of sorts and a lower receiver to also help in acting as a 'jig. I do not know the gap or what is needed heat treat wise to get it going again.

Can you guys give me your input and opinion on this. I figure I can use it as a receiver for a 'truck gun' i am getting pieces together for.
