Update: Not comfortable with the Egging or the the way the Rivets needed to be formed to attempt covering the hole.
Suppose it would have been strong enough ?, many seem to "egg".
However , considering the physical properties of the Rivet steel is not going to change, to suit my screw up. It's going to react to squeezing/compression in a predictable way : ie, won't just "hang a right" when it sees the extra space !!.
That's my story anyway. Demilled and starting a "new" build.
Someone very experienced in AK Manufacturing suggested I check the position of the Rear Sight Base, in relation to the trunion. The Gap at the rear dust cover, that started this whole mess is close to the space seen, where the RSB doesn't fully contact the trunion.
Before I start the project thinking I should move the RSB back a few clicks.
How does one MOVE that RSB Pin though ??
Thanks again for all the comments/suggestions.
Oh, almost forgot, Sears essentially told me to shove it on the Vice.
So NO more Sears Purchases from me. "Normal Wear and Tear".
No mention of Catastrophic Metallurgical failure . Screw 'em.
