Rear euro long (through rivets) trunnions are 4mm in diameter on AKM, AKS-74, or AK-74. Based on what I’ve read, it sounds like the best solution is to use 4.5 mm rivets if you can find the proper lengths and open all the holes up. You’re going to remove the barrel, right? We do not have any barrels yet. What size holes do the back trunnions have? You should get some 4.5mm rivets from Ak-builder and cut them to length to make short rivets for your project. The euro will not fit through a rivet channel on East German, Romy, Yugo, etc. In this case, a 030 rivet for 3/16 rivets is required. The rivets must be drilled into the channel. The crush side may be slightly undersized as a result of some increadsed expansion in the rivet channel. The inside of the machine will crush flat, according to my opinion. Short rivets, as opposed to long rivets, are likely to be fine, though you might want to go overboard in order to achieve the rounded head of a genuine round receiver. This rivet can be used with a 3/16 rivet. To drill the rivet channels, the drill must be in place. A 3/16 rivet will not fit a euro trunnion long rivet cavity without being drilled into it first. What AK’s have 4.5mm through rivets?Įxcept for PSL, I am unaware of any. A 5mm shank and a button buck from both sides are also possible options. Even if he protrudes slightly more than the shank, I still believe there is a chance of a foldover. A standard 3/16 rivet head is laegerier than a standard 4mm or 4.5mm rivet head. Typically, rivets should be ordered by the Lb, per M (1K), or by the letter. If you don’t have 29/32, you should use a 3/16 rivet (unless you’re looking for one). However, most AKs use rivets that are between 3/32 and 1/8 of an inch in diameter.ĪK’s are typically rivets with four and 4.5mm holes, but it can be difficult to fill them. There is no definitive answer to this question as the size of an AK rivet can vary depending on the specific model of AK that you have.
