This is the last phase of finishing a completed barreled receiver.

I begin with polishing that barrel pin with 400 grit paper to help it slide in smoothly. Sometimes these things get galled as they are pressed out. Let it spin in the drill press and hold paper against it.

Get muzzle end of barrel ready by removing the slant brake. Push in spring loaded retaining pin while turning brake clockwise to remove.

First you must align the rear sight housing on the barrel with the recess of the trunnion it mates to. I'm good at using the "eyeball it" method, works each time so far. Then the barrel gets tapped into the trunnion with a plastic mallet to get it started. I use a generous amount of RCBS case lube on the chamber end of the barrel and barrel pin. It does a terrific job of helping to slide things together.

We're back to the press to make it all happen. Muzzle end of barrel goes under the press ram, use two pennies to protect it.

The trunnion is supported by the edge of the presses cross bar. I use the two solid areas just behind the barrel pin. Then I press the barrel in until the rear sight housing is close to touching the cross bar of the press.

To finish the pressing, I move the trunnion up to this one solid area, and once again rest it on the cross member. Look through the barrel pin hole and stop pressing when the notch in barrel is in perfect alignment with hole.

Very informative series,thanks. I missed volume 1.I went back 6 pages but still I couldn't find it. When did you post it?

Just like removing the barrel pin, support the barrel where the rear sight housing is pinned on and trunnion edge so as not to have anything touching the rear sight housing, or rear sight block will be canted during the pressing. Get pin started in hole by tapping it in. Using just the press ram, push it in until ram is close to touching trunnion.

Use something made of hard steel about the size of the barrel pin and continue pressing until about a 1/16" of the pin is left protruding. I know one thing, this pin will now be a lot easier to remove in the future.

There's that barrel pin put back in just the way I found it. The barrel is now in, barrel pin is in and all the hard shop work is done. Give yourself a pat on the back!

This is the completed barreled receiver and the end of my series. Just find an AK-47 fieldstripping guide somewhere to put the rest of your goodies onto and into the rifle. All you'll need from here on out is a screw driver and maybe the needlenose pliers to get the fire control parts put in.

Thanks for your interest!

Hey, who jumped into the middle of these pictorials?

The first volume started out under newbie with newbie questions topic. LARifleman had some questions just as I was getting another build under way. So I released a series of pics as I was getting different stages done on the receiver. Remember, I'm just showing one way of doing it, there may be a few other ways depending on receiver being used and parts kit.

Who does a guy have to f*ck around here to get a tack? This whole series of threads should be tacked.

Send an IM to the moderator "mg34ss" and ask him to tack these.  I just sent him one.

My question is.....If the barrel pin holds  the barrel in, then it must fit through a notch in the top of the barrel breach.  Even if the barrel is pressed in a little canted...wouldn't the pin bring it back around when pressed in....in essence relocating the barrel to its factory original position?
