I have a post ban AKM that the brake was welded on back in the 1990's by KFS. I finally got the weld off but the FSB is stuck on. I also have the two pins and detent out. What could be holding the sight on? Are these sights held on some other way? I've looked for a NOS one but have had no luck. I looked at Polytech.com and aa-ok.com and they don't have any in stock. Thx

The detent is held by the cross pin. You need to push them out and reset (replace if necessary) the spring inside.

Are you pushing it off with a shop press?  The gas block and FSB require a great amount of pressure to move.

Your best bet is to use a Bulgarian AK-47 FSB.  I got mine from AK-Builder.

I got the detent, spring and both pins out but the FSB is stuck solid. Probably need a shop press to get the FSB off. I'll check with AK-Builder and see if he has the Chinese part or one that will fit. Thx

You will likely only find a Chinese FSB on gunbroker or the EE.  Here is the Bulgy AK-47 FSB that will fit on a Chinese barrel.  This is the gas block if you want to change that part as well.  If AK-builder doesn't have the parts, check APEX or Robert RTG.

Harbor Freight carries a 20 ton shop press that, like most Harbor Freight tools, is good enough for hobby use.  Coupons for 20-25% off are easy to find.

AK-builder has a barrel press kit that has several useful pieces to work on your gun.

Thx for the info. I got a dremel 80 piece kit make by drill master for only $9.00 and it did the job. Harbor Freight also has a 6 ton press that might work? If Curtis is taking new work maybe it would be good to let him do the work and maybe also do a bead blast and parkerize.
Edit: I ordered a 12 ton shop press from Harbor Freight after checking with a couple gunsmiths and local machine shops prices.  I don't think getting the FSB off will be a problem but getting it or another on on might be a different thing? aa-ok is out of bulgy FSB at present but I am on the waiting list when they are in stock. I've got the bug now and am looking at building a AK74 kit. I'll post back on this thread how things work out.
