Question: what is the difference between pre ban and post ban ar 15's?
Answer: If your SAW was built into a whole SAW, or in a complete kit form, before Sept. 13, 1994 (The Date), you are the lucky owner of a pre-ban receiver. If the gun was built after this date, or if the receiver was without all of the parts to make a SAW as of The Date, then it is post-ban.
