[ARCHIVED THREAD] - Front sight Jig

Posted: 12/15/2010 7:44:18 AM EDT

I made up a cheap jig that works well.

I started off with an old A2 style scope adapter and mounted it to a piece of 1/4 steel that is like 2 feet long.

Then I figured about where the front sight should be and drilled out a small groove in the 1/4 plate.

Then I took a small hunk of aluminum and ground down the sides until it fit into my FSB but I kept the top flat so it would fit tight to the flat part of the FSB. I also drilled and tapped two holes on either side of the 1/4" hole in the middle to bolt it down to the plate.

Then I took an extra front sight and welded it to a 1/4" bolt and ground down the weld.

Then I slide the forearm cap and FSB on to the barrel and bolt it to an old A1 or A2 style upper and go for it.

I hope this helps someone.

This cost me maybe $20 in materials. They sell for like $150, if you were a gunsmith or planning on doing a bunch of barrels I could see spending the money, but I dont plan on building too many from scratch so this was a cheap alternative.
