after last shot is fired, it locks back.

when you insert an empty mag and charge the handle, the bolt locks back.

but if I charge the cocking handle under control (very slowly) past the locking point when it's locked back already with empty mag, sometimes the bolt goes forward.

the make is VFC UMP
