buy a better tool,
and I keep saying this but so far no one has used this suggestion, go shoot 3 mags out of it as fast as your range allows then use a tool. |

Whack it with a hammer. Not sure if you are serious or kidding, but I would avoid this route. You can also use a vice - block off the sight and push the adjusting block/cylinder. |

I have the heavy duty polytech tool that costs $40 and it is close to breaking. It isn't broke yet, but it is damaged. I did shoot a few mags fast and oiled it beforehand. It is stuck pretty good. |

It is not the windage drum that is stuck. It might be, I don't know but I didn't try as I didn't need to adjust it as it was dead on side to side windage. It is the actual sight pin that won't move up and down. It shoots high. |

I hated to mess with it as it was dead on, but I wanted to know and I was hoping maybe bringing it back and forth would free up the sight pin. I will just use more penetrating oil. I just hope it doesn't break my good tool. If it does I won't have anything else to adjust it with. |

Sounds like the finish has slightly welded the post in place. Try heat, and wiggle it both ways to see if you can free it up. I never have any trouble with the sight tool that is integrated in the cleaning kit.

I took my SAM7 to the range today and had the same problem. I could not move the elevation at all. Windage moved but couldn't budge the elevation. I broke my sight tool also trying to move it. I sprayed it with balistol and going to let it sit in the safe for a few days.

The sight post (pin) on my 104 is like yours. I have the heavy duty old Norinco tool also, I've had it for 20 years and never a problem. That 104 bent the heck out of it, I was shocked. I've adjusted many a sight over the years and was shocked when it bent

It is tight.
I used a small torch to heat it up, and many doses of penetrating oil. All I have done is break four tools, one cheapo, and three of the ones from the buttstock kits, and bend the heck of the heavy polytech tool. I'm getting kind of mad. This is bullshit for what should be a very nice AK. I wish I hadn't bought the damn thing now. |

OP - I have seen several posts about 107FR front sight post being stuck.
Actually mine had the same problem. Mine was not painted over stuck or some oil will loosen up stuck. I tried pliers and ended up marring the metals without turning the sight post any. Just not the right tool to use... Invest $30ish on a Magna-matic AK sight tool (made in USA). It is over-built & very well made. It moved my 107FR's sight post and the sight post was REALLY tight fit. |

Mine is stuck, too, on my 107FR. I need elevation adjustment, not windage, and I've already broken my front sight tool. Haven't been able to move it yet, so I'm still hitting about 8" low at 100 yards.

KVAR makes an AK elevation sight tool that fits over that top of the front sight post - It gives it enough leverage to break free any frozen sight. I had a SLR101S that was stuck like your - broke multiple regular sight tools - The KVAR tool took (part number AA1401) care of it in about 5 seconds.
Good luck |

This was my same experience with the 107FR years ago. Went through countless tools, even tried heating it, but no luck. Ended up sending it back to Arsenal to fix it because the FSB was horribly canted anyway. Got it back and it was canted the opposite way and post was still frozen. Got rid of it. Expected more out of a $1K AK.

Somewhere someone made a sight post adjustment tool from a GM brake caliper line end bolt, since the bolt was hollow down the center, it bolted the flex brake line to the caliper and brake fluid traveled thru it. Placing the homemade tool into a battery powered micro impact driver broke loose even the stubborn sight pins. The shock from the mini impact driver (looks like a cordless drill) just eventually broke it loose. Either the pin will break loose or just plain break. You might want to google search for it ...IIRC it was either here, AK files, or The AK forum. Hope this helps

Update.
Got the magna matic "unbreakable" tool today. That sight broke it within 15 seconds. That is one tight sight. It has been lubed with penetrating oil throughout the last week, and that sight didn't even budge it just cracked the tool yet again. It still works on normal rifles, but there is a deep crack all the way through and its lost most its strength. Another wrench on this rifle, and it would break apart.

Hey, if the rear sight is on the letter setting, its the battlesight setting which is the same as '3'. You will be high at 50 and way high at 100. Put the rear sight on '1' which should zero at 50 yds. You'll find it will be a much smaller adjustment if it needs adjusting at all. The 100 yd zero is roughly 1" low at 25, 0 at 50, +1 at 75 and 0 at 100. Once you do this the rear sight will be indexed (approximately) for the other ranges, so to shoot at 200 you put it on '2'.

I was waiting to see how yours did before I ordered one, guess I won't be now. I truly know how stuck that sight is, as mine is the same way. I've tried turning it with a pair of pliers and it still won't budge. I'm scared I'm going to mess it up if I keep trying different ways to turn it.

Here is some pics of the tool. The crack is hard to see but it is there on both sides. It flex outs when you are using it now and the crack shows more so. Too bad as it is nice tool. Yes it should likely be replaced. The packages says they will replace it if it breaks under normal use.

I will report back on mine when I get the magna tool in. Should be getting it this Saturday. My front sight is stuck also. What the heck is causing these sights to be that stuck that a well built tool or even pliars can't turn it?
I've tried needle nose pliars and it won't budge. |

I'm right there with you guys. I bought my SLR107FR (my first AK) on 3/31/14. Since I saw this thread, I've been propping the gun up and filling the front sight with WD-40 every day. I also ordered a Magna-matic AK sight tool as soon as it was mentioned here, which I'm still waiting on. Unfortunately, I've made three buys from Midway this month, and UPS delivered the first two to the local post office for delivery, which added FIVE DAYS to the original UPS estimated delivery date.
If my Magna-matic tool breaks, too, my sheet metal mechanic brain is telling me to make a home-made wrench by cutting a piece of 3/16" thick stainless steel to where it will just fit into the front site housing, and then drill three holes in a row slightly wider than the thickness of the front site post, and dremel them into a slot that will barely fit over the post. Or drill and dremel a slot into the end of a 3/8" bolt, slide the bolt down over the post, and use a 9/16" wrench to turn the bolt from above. My FSP isn't centered, so I'd have to grind down the outside of the bolt to a smaller diameter until it would fit. Where there's a will there's a way. |

Maybe grind the damn post flat, completely flush with the drum. Then push the drum out and replace with a new drum and post.
Sounds like a pretty frustrated boat to be in. |

My sgl21 front sight was the same welded in place by paint. Snapped the magna matic tool on the first turn. I ended up using a screw driver with a thick shank cutting off the top and cutting a groove in it.clamped a set of vice grips to it for extra leverage and finally got it to break free. Still use that tool to adjust all my ak sights. The magna matic tool is awesome to adjust windage but the elevation adjustment ears are just like all others cheap and flimsy.
