Well, maybe not a blowtorch and I haven't had the need for pliers yet, but this is what I have to do sometimes to get a stubborn FSB off. In that jumbled mess of barrel vise blocks and C-clamps is a Colt LW barrel. A member sent it to me for FSB removal. I was able to get the relatively intact rear pin out with this setup, but the front pin is headed for the mill. This will be the second pin that I couldn't get out using conventional means.

Another member, h8mtv, sent me a Bushmaster superlight barrel a while ago with an identical problem and I was able to get the stubborn front FSB pin out using a Bridgeport mill. I'm hoping I can do the same with this one.

MAPP setup from Lowes. I was using very low heat, just enough to heat things up. It helped on the rear pin, but it was basically intact. The head of the front pin was mushroomed and the mushroomed head had been removed flush with the FSB. That makes it extremely hard to get a good hit on the pin.

Should you have that torch near all those volitale pertoleum products????

I've got it all under control. Here hold my beer and watch this.............................................



Operating a torch around volatile chemicals isn't an everyday occurence for me, but it is something I do quite often.

MAPP gas and Oxygen, this is some serious bench-top torch BTW, I gave up the idea of removing the FSB off my BM Superlight before I do severe damage to the pin head.

Have you ever tried a shop press? I beat the hell out of a FSB once with a much less elaborate set up and wished I used my FIL's 20 ton press ever since.

Those tapper pins are harder than wood pecker lips. I have removed a few FSB in my time, but never had to have one machined, nor used heat. They do not have solder, so there is nothing to soften. If you have a bridgeport and vice, it will provide a lot better platform to knock the pin out the way it went in. A rugged wooden bench like you have, still will give/flex a little, thus some of the force you need via a good punch and hamer is absorbed by the wood. The steel Bridgeport will give you much better results since more direct force goes where you need it opposed to dispersed force via wood/alum. combo.

This FSB came to me a bit beat up and to date, if the pin is intact and unmushroomed, I get it out with little or no damage to the FSB - nothing that can't easily be covered. The only two I haven't got out came ground flush with the FSB, and like I stated before that makes it extremely hard to get a good, solid hit on the pin. If you are hitting pin and FSB, you are losing almost all of the force needed to get the pin moving.

Thanks, Jack. I hit the bottom and the sides of the FSB with heat, hoping to heat the FSB up and not the pin, trying to develop the smallest clearance possible to get the pin moving. In this case, it didn't work on the front pin, but it did on the rear.

Your very welcome. Let me know how you make out with my suggestion with the set up on a steel surface. It is difficult to keep the drft pin in place since the tapper pin is round. I always used a pair of vice grips to hold the drift punch from slipping, after it got me once when hand held, ouch.

Excuse me, tapper pins round (at each end).

The owner wants it intact, if possible. I agree with you in a way, but a FSB that is mated with a barrel is hardly useless, even if it doesn't have the "coveted" and even more so useless bayonet lug.

Been there and done that today. I took a decent whack to one of my fingers with that sledge you see there. Some things are learned the hard way.

C'mon man, just whack it with that sledge a few more time. Beat it into submission! Who do you think the Police are going to believe.......

If it weren't for the fact that the owner requested the FSB intact for future use.................................................................................

Kinda sounds like the title of an S&M movie or something.

I will be attending an M16 armorers course in about 6 weeks or so. Supposedly we are going to completely disassemble and reassemble the entire rifles many, many times over two day's time. Are we going to have this much fun with front sight bases?

In the two stuck pins I have had the "pleasure" of dealing with, no amount of even the best penetrating fluid will help these. I have used Kroil, but I had none available to use now.

I too fought FSB pins on a Bushy superlite barrel. I bought the special punch for the pins from Brownells, but the pins were tougher.It broke after a dozen blows with a 4# hammer. Finally got them out after using my entire supply of cuss words.

I invented a few new ones today, after I whacked my finger with that sledge. It was a glancing blow but an eye opener, none the less.

I am in awe. That's some magnificent application of engineering to stubborn inanimate objects.

The only thing is, you can barely make out the barrel in all the blocks, clamps, and other medieval barrel torture devices. I'd think that would intimidate the pins out all by itself!

On my first build I got a barrel, and had to assemble it completely. Whew! That was a pain! When I got the FSB in position (after much creative cussing and threatening), I really wondered why all the parts that were supposed to come apart eventually had moly grease, but this part-which as I mentioned I had to assemble myself-didn't call for it. I have it figured out now: it's to keep Mongo and others of like talent busy.

(And I'll NEVER buy a bare barrel when I need a complete assembly EVER AGAIN.)
