It could probably be done, but I wouldn't do it. There is only about .3" where you could thread it and still clear the gas regulator. Add in a thread relief cut at the back of the barrel thread, and/or in the attachment itself, and you're going to be down to a 1/4" or less of real thread engagement. However, the barrel is still .610" in the "skinny" portion, so you would be able to thread that 1/2-28, albeit the barel would be a bit longer.

After addressing this issue with my gunsmith, this is the solution we came up with. Although my 556xi is 7.62x39, I am going to have the barrel cut and threaded for 1/2x28, and then overbore the 1/2x28 5.56 QD mount to .30 cal. |

I don't want to wait for a 10" barrel assembly, and frankly, they will probably be asking too much for it anyway! A cut and re-thread only costs $100, whereas the new barrel will probably be priced around $300. |

update, my gunsmith starting working part time at the local shop I often visit. he said there was enough meat for a chop and shoulder ahead of the gas regulator.
However, the barrel would definitely be a little less than 10". Somewhere around 9.75 to 9.5 inches. Hard to be exact as the hider is still on. |

Sig released the guns first and accessories are next. They do have the 10" barrels but they are currently just on the pistol version until they catch up. |

Just buy the pistol version and SBR it would be the easier approach IMO, if an SBR is your first priority.

What is 41P? Disregard, looked it up. |

Mine is with my smith right now getting chopped. It is the 556xiR, so the barrel dimensions will be different.

Well form 1 came back in under 30 days...
Is Sig ever going to release conversion kits for this thing? I would rather buy factory chopped barrels, but am willing to chop the 5.56 barrel. However, if I can't get a 7.62x39 conversion kit, to go along with it, I might just get a refund on the stamp. Will give it a few months and see what happens. |
