How to remove the front sight block
« on: September 21, 2006, 12:02:11 AM »
A while back I posted how I removed the FSB on two of my SKS rifles to repair bubbas handiwork. I do not have a press so I used a gear puller, part of a flaring tool and a piece of aluminum. First I used a hammer and apunch to drive out the two pins that hold the FSB in place. The flaring tool was placed around the FSB between the bayonet lug and the front sight.  The gear puller is hooked onto the flaring tool and the block of aluminum placed between the muzzle and the end of the shaft of the gear puller to protect the crown.  The screw on the gear puller is then tightened.  Here are some pictures of how I did it.

Bravo! I have been looking for a method to remove the FSB using ordinary tools and will keep this in a file. Now....post some pics of your method to reinstall it.

I just lightly oiled the outside of the barrel and inside of the FSB.  I then aligned it best I could and used a hammer and hard wood block to tap it back on.  It is MUCH easier to put back on the take off.  After I had it the proper distance from the muzzle I used two large adjustable wrenches (one on the gas block and one on the FSB) to rotate the FSB on the barrel so that it was straight and not canted.  Finally once everything was how I wanted it I replaced the pins.  One hole did not quite line up with the slot in the barrel and I had to drill it out slightly to get the second pin back in.

Good deal. I have converted one of my 3 Norincos into a dedicated deer rifle. I have drilled and tapped the receiver and bolted on a Chaote mount, a 3-9x50 scope, shell deflector, and now feel comfortable with removing the FSB (temporarily) to streamline the rifle. I am also removing the front sling loop, that piece of metal hanging from the side of the barrel does not help accuracy. Now if I can only get some plans to bed the stock............. Thanks alot pal.

Please?????????? Good information here for all to know. Thanks.
A block of brass would also work if you dont have aluminum in the shop.

Anything softer then steel would work. The main idea is to protect the crown of the barrel from the hardened steel of the shaft of the gear puller.

I have already begun by removing the pins. I have to borrow a puller, but have all the other components. I am also wrapping the crown with duct tape to further protect it, and will remove it as the FSB assembly comes loose.

I use the "2x4" method.  First, I punch the pins.  Then, I put the rifle muzzle down on a thick piece of carpet.

Then, I take a long 2x4, and longwise, strike the base of the GB from the top.  I don't swing it down, but rather "punch" down, as if I was setting a post in a hole.  Usually takes about 4 or 5 times to come off.

Does that make sense?

A BIG brass mallet works wonders as well. I could'nt wait to borrow the gear puller, padded the crown real well, and 3 sharp raps to the bayo lug with the brass mallet took it right off with no marks or damage.

This is great info, but I cant even get the pins out.

I know what you mean, I had a hell of time getting mine drifted out as well. I didnt have a drift small enough and had to cut the end of small drill bit off and grind it smooth to get the pins out. I got them out and cleaned up the barrel and touched it up with some cold blue. I aslo commited the collectors cardinal sin and cut off the sling loop, Dremeled it smooth and blued it as well. I have my eye on a SIMS De-resonator, wonder if it is worth the $12.99.

Is there any other implement besides the flaring tool that would work the same?

The gear puller I had would not grab onto the sight block alone.  Anything that will fit around the sight block that is sturdy should work.  I'm a plumber so I already had the flaring tool.
