I know very little about semi autos, just wondering could one rebarrel a 551 with any custom barrel or would you need the actual factory barrel. I know the original barrel has all sorts of exterior contours on it but would a custom barrel do it.

Re: Sig 551 rebarreling
Its not actually mine its a customers rifle. He just want something a bit longer. The only thing I need to know is, is there any difference in a barrel on a semi auto and a standard bolt action barrel, poting etc.

Re: Sig 551 rebarreling
These guys sell Sig 551-556 parts including longer barrels. Think its would be prohibitivly cost/labor intensive to start from a blank.

Also the SIG (Swiss made) barrels are suposedly much better and more accurate than the US made 556 ones.

Re: Sig 551 rebarreling
Unfortunately thats not really an option for me as Im not based in the USA and obtaining components such as this would be vertually impossible. A custom barrel is my only option and assuming its just a matter of chamber and fit, this is the way I must go.

Re: Sig 551 rebarreling
Dang I would assume it would be easier for you to get a 551 barrel than it would be for us here...cant you just hop a train under the chunnel and get one in Europe LOL.
I assume there must be some sort of import restrictions that make it not that easy?
Just specifying that I'm not a gunsmith but I was a machinist. Having said that and looking at the barrel I would say one could be turned down esp if you have the take off to use as a sample. Only area I would suggest looking at before attempting would be the gas block mating area to see if its ground or turned.
