even if there was a definitive answer, there is no mechanism for enforcement. considering how rare it is to be even be ask to provide a form 1 or 4 by some form of LE, the likelihood of domestic parts count becoming an issue borders on hitting the power ball.
922r is something that vendors, distributers, and manufactures need to be aware of but once that rifle/pistol is in circulation pretty much anything is game.
Thanks. I ordered a railed P553 yesterday. I've got the nicer Swiss-made stock from the 551 so I'm ready to go when the stamp gets approved.
For re-threading the barrel, is that a favor that was done for Mr. Vickers or can a lowly schlub like me send mine in too? A 5.56 can is my next purchase.
Also...any feedback on a proper optic for an SG553? Certainly an Aimpoint or Eotech works but my Q is more about what is typically equipped on SG553's for duty work. ( I'm not a fan of the 'branded' SigTac stuff that's like every other lower end optic made overseas.)

You should not need to re-thread the muzzle. The very first 553s imported had bare unthreaded muzzles, hence the requirement to have them threaded. All subsequent 553s imported into the US were threaded 1/2x28 from SwissArms, which simplifies find muzzle devices. Unless your 553 is one of the first imports with a plain unthreaded muzzle, you are good to go. If you want to re thread to 14x1M LH, as was standard on 552s and some 553s, it is not possible to go from 1/2x28 to 14x1M LH, as the latter has a thicker O.D.
As for optics, an aimpoint t1 is pretty much ideal on the 553.
Enjoy your new 553!

sweet, thanks. I did a bunch of image searching for Stgw 07 in Google and came up with Eotechs and Aimpoints almost exclusively. Guess it makes sense since it was released in 2008. Any idea if the T1 absolute cowitnesses with the Sig sight kit? I've got a cheap red dot on my 522 and does with the diopter kit.

I am looking at buying one of the diopter sight versions. I briefly handled a sig import 553p at a gun show and it did not seem to have the tritium inserts in the sights.
Does the M+M version have them? Are they still importing them?
Can any gunsmiths stateside retrofit the Sig imported version with tritium inserts?
maybe using this:

ToolTech should be able to do it. I'd be hesitant for the used set as there's no guarantee how long they are good for.
edit - I assumed these were the used barrels they also sell. The description shows these should be good for 12 years. Hmm..I'd like a pair of them. Wonder what the purpose of making it a flip-up if its in the hood? Or, does this allow the entire hood to fold flat?

No idea about the factory railed Swiss guns but my Swiss 551 with B&T mount will co-witness using a T1...when diopter is set to 100. It is pretty terrible trying to do it using the full circle apertures.
I have a cheap Wal-Mart red dot on my 522 and it cowitnesses the optional Sig diopter kit I put it on it and I agree you've got to have the 100yd V notch selected. Guess I should swap one of my Aimpoint Pro's on my 551...that will be a closer estimation of the P553. It will be here soon enough (week from tomorrow....Ground shipping and the holiday pushing it into another week, much to my frustration).

Woot had SigTac sights for $99 yesterday so I ordered one. Likely a stopgap I'll put on my 522.
