GHK Sig 553 (pre2019). 

Comes with 6 leak free mags, the folding stock and quad handguard pictured. Also upgraded internally with a maple leaf barrel and rubber. The mags themselves have tape wrapped baseplates as it's one of the points of failure with these mags (along with the couplers), and in this case one or two of them have split. Other than this, the gun is one of the most realistic I have owned, the finish is exceptional and it manages to go through around 3 mags of BBS on one fill, even in the colder months. I have always been astonished by how efficient it is. Unless mentioned this comes with no further attachments, it will also come with the stock SIG pistol grip, but the Hogue can be thrown in for the right offer.
