I will cover the removal and installation of the rear trunnion into the new receiver.
Remove the torch cut rear section with buttstock from your bag of goodies. Grind off all four rivet heads completely without going all the way through the receiver shell. Now you can pry both sides of receiver away from the trunnion and pull it free. Now remove buttstock from trunnion if attached.

Now to prepare the rear trunnion, both rivets have to be removed. There's no way around this, so what I do is use a slightly undersized sharp drill bit and drill completly through the rivets using a press. Don't forget to center punch those rivets so the bit doesn't walk.

Now, what's left of the rivets can be punched through and out of the trunnion.

Slide that trunnion into your new receiver until the holes line up. Push one of those long rivets all the way in 'til the other end sticks out the other side of receiver.

This technique varies by builder, but I will show one way of pressing the rear rivets.
I place the receiver in a bench vise, with the rivet head supported by a dimpled out piece of angle iron on the one jaw. Tighten the vise 'til the straight end of the rivet shank almost flattens to the diameter of a rivet head. Now do the same thing with the second long rivet.

The end of the rivet that was almost flattened in the vise can now be given a somewhat button shape by taps of a hammer and punch around the edges.

Now that the front trunnion and rear trunnion are rivetted to the receiver, I will begin to cover the 5 trigger guard rivets tomorrow as I remove and replace during this live build as it unfolds as Volume III, The Trigger Guard.

Thank you Atreides. Are you a Dune fan perhaps?
Just passing on some knowledge, and showing what basic tools are needed to make life easier during the build. Problem is, you just can't stop doing only one build!  |

If you have the rear receiver piece from the kit you're working on, place new receiver perfectly beside it lining up the top hole you already have drilled. The bottom hole of torched receiver piece will show you where to drill that second hole. Drill it small just in case you're off a little.

so why not a shaped buck board on the straight end of th rivet when you push it in the vice? Wouldn't the rivet squish in to a button?
