SLG Defense 07/02 FFL/SOT
Just to update, picked up the 553 today - thank you again to each of you for your insights. Grey/green with diopters. Sounds like the railed version is running about 3 months and the diopter 6 months. I learned that the diopters are less common on the 553 (outside of the US) given the ballistics of the short barrel - generally a red dot on the rail is good enough accuracy for the intended range.
Regardless I'm very pleased and impressed with the build quality and details. This is much more solid feeling than something like an AK and the trigger feels great too.
If I had to do it again, I might get the gray with black furniture but that's a relatively simple change. I'm very pleased with the diopters, especially if this is the only one I get. That being said, the trend to go purely railed / red dot makes a lot of sense too. I think if I had both I'd probably just grab the red dot one, hah.
A limited boutique 553SB run was available a few months ago mit diopters and rail.
No clue if any will end up on this side of the pond.
They will eventually reach for the low hanging fruit - imports.

A run of 551SB's with diopters and rails is going to be imported, so having the same on a 553 seems logical to me.
Was able to get the SG553 out on the range. On the 4-position gas valve, it would not cycle on 0.9. I needed to flip the valve to 1.2. I was shooting XM193.
I’ll get a picture up soon. I ended up mounting a Sig Romeo 5 (high mount) on a B&T rail and it lets you use both the red dot or diopters (through the bottom of the mount).
The gun ran great after fixing the gas issue. Trigger a little heavy on the take up but very clean breaks and could get 2-3 rounds off staying on target. The shells did remove a little paint outside the ejection port. Overall very solid and smooth feeling. A lot of fun.

Does anyone know how many rounds the recoil spring and gas valve last? Trying to figure out spare parts. Firing pin and Extractor spring?
