Need to go thru a stock no 740-200 (BXA) that not releasing with the hold down nut tight. It is a piston type lock that works as long as the lock down nut is loose. Looking for an expanded parts diagram for help in tweeking before I mess it up. Any leads or links where to look? My email is qspot@tulsacoxmail.com if you have any info. Thanks in advance.
