RPK Receiver choices

[medicmike]

Hey all,
Recently hopped over from the FAL Files. Just received a pretty clean RPK kit and will need to decide on what receiver to use. It came with a set of dies to punch the bulges to clear the larger trunion. Would be happy to go with an 80% (bentmetal or other) or just buy a complete reciver. Anybody put one of these together?

It came with a set of dies to punch the bulges to clear the larger trunion.

huh? who made the punch & die?

i really doubt it would work, trying to stretch the steel, without having a full die set and press that hits home.

i would be interested in seeing pics of the punch and die.

a friend of mine built up his bulges separately. after cutting slots into the receiver sides, he tig welded the bulges onto the receiver and dressed the welds down. a lot of work, but it looked very nice.

at this point in time, using a vepr receiver and fixing the rear angle cut is one option.

The punch and die appear to be home made, haven't attempted to use them on a scrap piece yet to see how well they work if I get time I will give it a shot today or tomorrow. How about the option of milling off the bulges on the trunion?

Ok here are some pics of the punch and die hope these work.

Guess these will only work for punching a flat. I suppose the punch could be milled to fit inside a bent receiver.

All I see is the dreaded red x.

As a side note I dont think milling the bulges off would be a good idea the thickness under the bulges is already in excess of .035 under the thickness of a standard trunion.

The pics are showing up for me when I view the thread. Here are links to the pics, hope these work.

All I get from those is Forbidden you are not authorized to access.

Centerfire Systems is selling Romak 3 kits, and state that receivers will be available. Would these work for the RPK?

I think they are too long and cut for a big ass mag.

Trying a different photo host, here are links to the pics again.

Just remember that the RPK trunion is a few thousanths narrower than a standard AK and the receivers tend to squeeze in and deform a bit wihen assembled.
