I think your right it looks like the stubs will be a b*tch to get out, until i noticed the weld holes.
when you say brazed in and welded ?
do you mean they brazed the reciever to the trunnion first and then spot weld in place or is/would it be possible to braze rather than weld?????
if so then we would have to drill out the trunnion holes (aka AK trunnion), then heat up the receiver to remove the brazed in stub sections??????????
