 Draco canted sight DIY fix - possible?

I have a SBR Draco that has a canted front sight. Although it can be zeroed with the sight post at almost full deflection to the right this is clearly isn't the way it should be installed.. The canted sight is driving me to avoid shooting the rifle.

Has anyone on the board driven out the 2 pins and realigned the sight? Since it is a SBR repair/replace options are limited. I would really like to fix this annoyance myself. Any guidance would be appreciated.
thanks

I did mine; pretty easy. Knocked out pins, soaked in Kroil over night, heated FSB with a propane torch, and wack straight with a 2lb lead hammer on a 2x12.

OK, I'm getting ready to do this. Are the pins driven (right = ejection port side) from left to right or right to left?
The info on the Internet for gas blocks and/or sight posts seems to be contradictory.
Thanks.

They are straight pins that are pressed fit. Usally one side will look more "peened" so I always knock on the cleaner looking side of the pin. Don't forget to soak it overnight.

Is the sight misaligned or the barrel trunnion ?

Sorry that I couldn't post any images, my camera couldn't do it justice.

I finally got around to the fix this weekend. It went very well. I bought a length of 1/8" drill rod at Fastenal along with a new (read very sharp) 1/8" twist drill.
The rod was cut into 1/2" pins and heat treated using a method described in a you tube video. I hung the pins by a magnet over some oil in a cup. I turned the propane torch on the pins until the pieces fell into the oil.

I drove the old pins out, straightened the sight/gas block into alignment, on a drill press re-drilled the number 31 holes in the sight block and barrel to a 1/8" diameter . Drove in the new pins and test fired the Draco. It is good to go.


One note, I replaced the upper cover with a Texas Weapon System rail and peep sight. Sighting through the peep and the former rear sight block really brought home how far to the left the front sight was canted. The peep sight helped a great deal in aligning the front sight to be closer to longitudinally true.

Another note, I had tried to buy a laser bore sight (in the chamber version) to help make everything line up, I waited more than a month for delivery. I gave up and went ahead without that added tool. If possible I would recommend using some type of bore sight tool during the process...just to be sure.
