Unless that's just the the lower they're referring to. Given the weight reduction, I was assuming it was both.

It is just the lower. I have the alluminium and the steel lower for my 553, the difference in weight is noticeable. I dont think it would really be possible, engineering wise to use a non steel upper on this design.

I also agree that it wouldn't be possible to have a stamped aluminum upper of the same dimensions. It's likely just a case of their marketing people not being clear. The do have the steel lower version shown as well without the AL in the description. It's odd that they don't show the 550 and 551 with the same AL option as those are the versions that were recently imported.

Okay, that makes sense. I believe SIG 551A1 was fully aluminum, so I wasn't sure if that was the case with this (only, obviously, WAY better quality).

The KAC SLICK that was part of he SCAR trials was little more than a Sig 552 with a monolithic aluminum receiver. God I still want one.

You're in luck. JDI is importing a batch of 552's and you can buy an aluminum receiver off of their website.

No, the 551A1 was a steel upper. Only the 522 had an aluminum upper.

Me too man. So beautiful.

Hard pass for me on a new import with JDI markings. The 552 operating system is inferior to that of the 553. It’s a neat reference piece for an advanced collector looking to fill an iterational gap. I’m fortunate to own one of the Sigarms import marked 552s that came out of NC ALE. The markings are what make it most interesting to me:
“SG 552-2 SP Commando “.

I bought mine before any contemporary Swiss 55x imports were even thought possible. If I did not already own the 552 and if given the choice today, I would choose the 553 no contest.

I'm not a fan of the aluminum lower. I have 551-LB #49 and wish it came with a steel lower as it is front heavy and some extra weight in the back towards the receiver would help. This is with the stock attached as well.

I assume you have a JDI one then. I think the SIG imported 551s had steel lowers as mine does. I think the alloy one was good for the 553 but I can see how a 551LB or 550 would be pretty muzzle heavy..

Yup JDI import 49/51 and agreed on the 553. I might be getting a 553-LB and I'm thinking about just going with a steel lower for it as well.
