Barrel re-profile question

[wetidlerjr]

If you think the FSB will cause you angst, just chop the FSB down and use it without pulling it.

I agree and I've done that, too. Worked out great for me.

Thanks for the advice.

There are very few places you can ship a barrel and fsb and say, "drill holes through my barrel, pin this on and make sure it's perfectly straight".

And they'll probably tell you they'll try for a price but the result, ruined barrel, perfect job, or canted sight, is your problem and no refunds.

You haven't done much research. I'm not going to tell you where to go. Sounds like you are scared to dive in. Look at it this way.... If Colt can pull it off anybody can. It isn't rocket science.. Maybe give Marvin a call.

I said on the first page that I know of a shop, you can just PM me if you want an answer...

I believe OP wants a 20” even though it wasnt specified in this thread.

Emphasis mine. Only way to know is to ask.

As for OP, i believe it depends on lathe, though you could remove fsb, but keep profile under it same for reinstall of same fsb with new taper pins.

I'm sorry, yes, I'd like a 20 inch barrel.
