Well guys, I fitted my rear trunnion and after drilling the rivet holes I noticed that the hole was to close to where the large selector hole is. With the rivet in place I couldn't insert the selector. So I had to remove part of the selector that tensions on the receiver. When I compared the rear trunnion rivet holes with my other AK's the on I got with the AK-74 parts kit is longer.

Anyone else have this problem? Did I somehow get the wrong rear trunnion? I intend to try and work around this problem but I was just wondering if I was the only one with this problem.

This is normal. AK-74 uses a different trunion than a AKM. Ak-74"s trunion is a little bit longer. Here's a picture the AKM is on the right.

This is a 2nd type of trunion. The AK-74 kits from about a year/2 years ago had these trunions. K-Var sells them now as "RPK" trunions.

That is the same hole pattern the Krink side-folder trunions use BTW...

You learn something everyday... I guess if I build another AK-74 I'll be sure to use the AMD or AK47 trunnion. Just wish I had known about this before drilling the holes. Oh well.

I went ahead and ordered a regular Romanian AK rear trunnion from KVAR to use in my Tapco Flat build '74 because I don't want to fool with filling in the holes. I think I'm going to try and make my own flat to bend in my 555th jig also to see how that comes out. At least we have more options nowadays.
