I have a Swiss 552 handguard and a retainer that will allow it to work with the sig 556. I also have a gas block that has a folding front sight.
If your looking to create the 552 commando look then send me a message about this parts.

SOLD

If it's a proper Swiss 552 handguard, it won't work on the 556, regardless of what handguard retainer ring you have. Unless you have a ring I have never seen; anything is possible.

 

[Duck_Fan]

With the jmac custom retainer you can which is what I have.

I have the same JMAC retainer rings, and they allow you to use a cut-down 550 handguard on a 556. An actual Swiss 552 or 553 handguard will not work on a 556, regardless of the ring, because it is too short.

Also, who makes that gas block? I have only ever seen it once before, and it may have been in some other post of yours.

The jmac website says it will work with the 552 the only reason I am not using it is I need an 8 inch barrel and I have a 10. The gas block I have no idea the maker. I got everything in a bundle including the old school laser devices flashlight that went on the commando

Copy and paste from JMAC sight...
"In order to install on this on the above 556 rifles you will have to cut down an original 550 hand guard."

And I know this to be true.

Also, a barrel swap is not an easy job on these guns. I'd advise you to stick with the 10 inch.

Yeah I got my sbr paperwork and was all excited to make a 552 commando and to my disappointment when my barrel was too long and it didn't line up correctly. Didn't feel like going through more paperwork again to cut it more.

Get a 550 handguard, cut it down, and use that JMAC ring. Yo can have the look with your gun the way it is.

This is a P556 with cut-down 550 handguard and MFI ring.

I see the issue now. You have the Xi. I have very limited experience with the Xi, so I can't really advise you on a good course of action.

Your rifle is better looking and I think I'll take your advice and just find a 550 handguard and find somwonw to cut it down and fit it for mine. I wish I could have an actual sig lower but my job requires me to able to accept AR style mags.

 

[25129]

The Xi lower looks better than the Swiss STANAG lower anyway, in my opinion. Are you located in GA, by chance? I ask because I know a gun store that had an Xi factory SBR for the longest time. It finally sold, and an employee told me that someone in LE bought it.

UPDATE- After some people have been asking for price I had to do some research of the price and I think $225 for all three.

I have just the retainer ring without the handguard if anyone is looking to buy one hit me up.

Greetings, they have been sold. Keep looking you might be able to find some if you dig enough, or you can see if JMAC customs have any in stock.
