AK Mag Catch Pin Mushrooming?

[ambis]

Hello,

I just installed a new mag catch spring and pin. What do I do to stop it from drifting? Do I just press each side using a shop press until mushroomed?

That's how I do it. Can also use a punch and bucking bar

BB+ Anvil + Hammer. Done.

You gotta get ball bearings, toothpick, paperclip, hammer, and stapler.
Put a ball bearing on either side. Throw the paperclip, hammer, toothpick, stapler aside, you dont need those.
Then hit with hammer.

I use a ball peen hammer to flare it out, just back the other side on the anvil on my vise. If there isn't enough to flare out, then I hit it with a 5/32" or #22 slightly. That will give you something to flare. Messing with ball bearings are a hassle for me, a good old ball peen hammer can form a rivet head and it will flare the pin too.
