Previous way:

Unload and make clear.
Clamp in bench vise.
Using a torch, heat front sight block until you can push the pins through.
Push pins out.
Remove FSB.
Redrill holes to 1/8".
Put FSB back on in right alignment.
Cut off bits of 1/8" round stock to fit holes. Tap into place.
Check alignment again. If all of the tapping and drilling has caused it to be in the wrong place again, repeat from step 1.

Total time: several hours.

My way:

Unload and make clear.
Determine which way the sight block is canted.
Using a towel to protect the AK reciever, clamp reciever in bench vise.
Go and find the largest screwdriver you can.
Insert screwdriver crossways into front sight block.
Apply about 720 inch pounds of torque in the proper direction until you feel the sight break loose and move about a degree.
Check alignment again.

Total time: 10 minutes.

:cool:

I like things that are stunningly simple, cutting the Gordian Knot kind of thing.
But what of the pins? Are they still intact?

Only problem I can see is the potential for bending the barrel. Things look simple on paper.

Not to mention twisting the barrel.

Several hours? You got to be kidding or cannot chew gum and walk.

Takes me less that 1 1/2 hours to fix any Century problem on an AK

The barrel was not bent, and the pins are still intact.

actually for a slight cant ya can simply put the S-B against a firm non marring object and smack the bayo lug with a brass or padded hammer takes a couple seconds..

As for the screw driver pry bar method ...... I'll be glad to sell ya a NEW FSB when ya break yours, they are only cast steel and not hard to break or bend.

When tapping it ya want to put the firm object as close as possible to the base on the opposite side ya want the FSB to go, this is good for up to about 15 degreees of cant more than that ya gotta pull the pins but don't use heat thats bad the pins drift out very easily with the correct pin punch, use the same method of bracing then tapping to rotate it then generally no need to drill out the pin holes usually ya can re-install the original pins if ya use a dremel with a diamond burr bit to match only the groove in the barrel which will be very little metal removed, don't grind the holes where they go through the FSB and ya'll be fine...... that method for FSB can correction takes about 5-10 minutes. to get into a half hour ya'd have to be pressing off FSB then Gas block or something as it really just doesn't take that long to correct a canted sight.......

BTW Trying to get more than a few degrees corrected without removing the pins can easily result in a cracked FSB band, the part that holds it on the barrel it will crack quite easily

Total correction was 2.2 degrees.
