551 mags are about $100.I have a 551A1 that I put a 556 lower on
so it could take AR mags.Pre-ban SIG mags
are hard to come by but not the AR ones.
The rifle is a little heavy,but I will take it over
an AR any day.Stock,and muzzle pinned,and your all set.
So I have one its a sig 556 xi. Believe they made them for a very short time 2014-2016 they had 300 black out, and 7.62x39 variants as well. They were phased out by the mcx's. It is probably one of the greatest rifles I have ever shot in my short lifetime, but then again im a huge fan of sig rifles so maybe it actually sucks. Its essentially an ak bolt/ gas system all built around a 556 cartridge. It is very heavy but it is very very very smooth. The trigger is smooth, the cycling is smooth, and its definitely a gun worthy of the space in your safe. They are fairly rare to come by. If you have the money to buy one and you find one I would say go for it.
I have a 516, it’s def heavy for an AR, but with a comp and a Gieselle trigger it shoots beautifully.
What I don’t like is Sig’s BS policy about selling proprietary spare parts. No other BCG will fit it, and they won’t sell you one alone, you have to buy a complete upper from them (unless they’ve changed that recently).
I believe the 516 has been discontinued as well now. Moving on to their lighter weight version DI M400 series.

If you can't find one, look at the Galil ACE. Same idea, different implementation. Available (maybe) online for around $1400, I think.
Mass Firearms had the SIG MCX for sale (out of stock currently) for $2089...
I wonder what an upper costs...?

Apples to oranges, I know... but, with pre-sale mods, why not?
