| I just got done removing the donut from my WASR AK-47 and now the detent pin won't pop out, it is flush with the edge of the front sight. I didn't hammer it into place, I just depressed it with a flat bladed screw driver. |

Quoted:
There's probably some preservative in the hole. Squirt some penetrating oil in there. Let it work awhile. Use a tool small enough to enter the hole and push the plunger in slightly and release it. I'll run to Ace and get some, the muzzle, etc, had lots of old Cosmoline on them. |

Thats good advice I sprayed a good bit of WD-40 onto the detent pin and so far it isn't popping loose. Just sprayed it down again and will let is sit for a few hours. |

Hit it with a propane torch while pointed down and let the cosmoline run out. Just warm it up with a match or lighter. No torch but will try a butane lighter. I heated that darn thing for a good 15 min, got some brown goo to ooze out but the darn thing will not budge. I sprayed it down with WD-40 and will let it sit for a few hours. |

You may want to try a penetrating oil instead of WD 40. Kano Kroil or PB Blaster. I've had good luck with both. If worse comes to worse you may have to remove the FWD frontsight block pin and spray some oil in that way. I found an old, 15+ year old, can of PB Blaster, just sprayed the area so I will let it sit over night. |

This happened to me less than a week ago.I too tried some CLP,whacking the sight base with a rubber mallet and several other things.
What worked for me was heating it up with one of those little cheap pen torches and then quickly hitting it square in the middle with a prick punch. It popped right out. |

You may want to tap it lightly on the side of the front sight base with a brass or plastic mallet and see if it will move Did that too with a wooden mallet and plastic screwdriver handle. No joy.  Have you tried pressing it in slightly with a small pin punch like the one in the cleaning kit (if you have one) or a small screw driver that's small enough to fit in the hole? |

I have tried that several times, the pin acts as if it is in solid, NO movement whatsoever. |

You're going to have to drive out the pin that's keeping it in the site tower. If that doesn't loosen it up you can try and push it out or get oil in from the rear. Don't forget that once you drive that pin out there is nothing keeping it from flying across the room. Once you get it out clean out the hole with some break clean or the like and use a drill bit to clean the hole out before you put it back together. |

So I'll have to remove the site pin to facilitate freeing up the detent pin? I'll work on it when I get home from work Mon. |

I would, that way you can make sure the hole is clean so it doesn't stick again. |

OTOH, if you decide to drive the fsb pin out, I recommend covering the detent with a couple of layers of electrical tape. Having it stuck may be frustrating, trying to find it and the spring after they've launched across the room is worse.

I was thinking of using small strips of GI 100 MPH duct tape to keep the pin in place. |

It can be nearly impossible to drive out that pin. You can bend the barrel trying unless it's properly supported. I'd shoot it at least 50 rounds and see what happens. I've done everything I can, I'll wait until I can take a day off and go to my buddies range and put some rds through it. |

Did you try knocking the pin out from right to left as your looking down the muzzle? Mine came out fairly easy with the barrel supported on a 2 inch piece of wood, using a punch and a medium size hammer. http://i21.photobucket.com/albums/b259/skidman/pin.jpg I'll try this method. |

They are not taper pins like on an AR, they are straight pins that can be knocked out either way. When I threaded my SAR-1 and installed the detent pin I had to take it to a friends shop and use a mill to drill the pin out, it wouldn't move. I actually broke a punch trying to get it out. Most people have good luck but occasionally you get one that has to be drilled. I'd recommend using a drill press and not hand drilling it out. You need to make sure you drill the hole straight. |

Do this next.Don't try anything more with it till you've exhausted this possible fix. My 0.02 worth. +1 Always try the easiest "fix" first. It makes life less complicated and more pleasant.
