I have a monster sear I am not currently using- got it in this package...http://www.uzitalk.com/forums/showthread.php?77780-Thompsonesque-MAX-31&p=757692&highlight=#post757692 but need to get another extractor for the bolt.
You are welcome to borrow it for a month or two (I do want it back at some point so I can get the 'Thompsonesque' upper running)...let me know you address and I'll pop it in the mail.
If you need pics send me your phone #.
