The G&G SIG 550, Sig 552, and 553 are all top quality built.
Stamped steel receiver, all externals are top quality materials.
IMO, they are the best airsoft version of SIG rifles made.
I have the 550, and the 552. I also have a real steel Black Special. And I tell you, the airsoft is identical in detail, to the real steel.
They also perform excellent out of the box. And I have had no problems with either.
The G&G SIGs, I think, are the best line that G&G make. They are G&Gs top price point guns at US$400. And about CDN$900. in our market. But well worth it.
I would put them against any other top quality airsoft gun made, for build quality... in detail, materials, strength and durability.
