Roll-pin slippage on Dboys AK74U.

[Lakonian]

So I picked up a beautiful Dboys AK74U, RK01S. Everything is pretty amazing on it, except for ONE really annoying (among few others) issue-Pin slippage.

Areas include: Top cover "pivot pin", sight pivot pin, and lastly mag catch pin.

Some suggestions were cover the pins in glue (didn't work), cover the ends with glue from a hot glue gun (works but looks like shit, and is very temporary), and spray the pins in Krylon, and the paint will shim the pins properly...

Before I go out and buy the Kry, I'd like to know if there are any other PERMANENT fixes... If you can help, please post

Much appreciated.
Cheers.

Take a large pair of pliers, and sqeeze about 1/8" from one end of the pin. It will make seration marks that will tighten on the body when you insert them.

Worked to make a center pin for an M16 metal body out of a nail.

flare one end of the pin...either by squeezing it (you don't want to crush it...just change the shape/dimension)...or by flaring it.

You can flare a pin by whacking it with a hammer onto a solid piece of metal....(the tail of a vice works well, another hammer head, or even the solid part of a big pair of pliers). If you heat up one end really hot and then let it cool slowly...it'll soften the metal and it'll "mushroom" easier. You can reheat it after and quick quench it in a glass of water to harden the metal.

Those are permanent fixes.

You can also make a new pin out of a finishing nail...if you need to file it down a bit to get it to fit, file it into a taper so it's a jam fit. I just did that today to make a new pin for a MP5 mag. Tempering the nail also makes it easy to work with.

In a pinch...you can use epoxy. Rough up the pin so the epoxy will adhere...put a glob on one end and really let it harden up. Then file/sand it back down so it's a jam fit.

If the hole is plastic...you can fill it with a pin head of epoxy and let it harden up. Before it's really hard...you can drill/file it out a little so it's a jam fit with the pin. Not really the best solution...but it'll do when you're in a bind.

If the pins are roll pins (i.e. not solid pins) you can try to wedge a finish nail in the hole and give it a whack with a hammer...that should flare the end of the pin easily (might get the nail stuck in the hole...so don't whack it too hard).

Best of luck,

Thanks alot guys!

Tys, you're extremely useful !

And I had my terminology a bit wrong, they're solid pins.. So, I guess they're not roll pins?
