Well, the title about says it all.  I'm looking for a can which will fit an M1A and the only thing i see advertised which looks like it will work is the above stated item.  No where on their site is attachment method mentioned.  There is no link avail other than for mil/leo and that makes questions kind of tuff to get replied to.  If any of ya'll have any input suggestions I would truly appreicate them.  Thanks in advance for your time and consideration.
