The background for SIG SG552 SEALS comes from the limitations of standard M4/M16 rifles(which are standard assault rifles for US military forces) in range and accuracy. The Swiss made SG55 series are regarded as one of the most accurate assault rifles in the world, so no wonder that some firearm experts favor these rifles over the M4/M16 series.
SG552 is the latest model of the SG55 series. This shortened model is used by US Navy SEALS and it uses standard 5.56mm Nato round. When SEALs adapted MP5 they asked Heckler & Koch to remove the burst-function, because they didn't need it. SEALs asked SIG to remove burst-function as well as requesting material changes to SG552 to improve it's resistance to rust. In this Tokyo Marui's electric gun that particular special feature has been imitated with new dark-grey coating.
For the electric gun SG552 SEALS has 20mm mount on both sides of the handguard as well as see-through magazine, which now has realistic replica bullets. New muzzle (which is beneath the flash hider) can easily adapt silencer and it current standard for Tokyo Marui(for Pro silencers). SG552 has completely new battery type , which is slimmer so that it can be attached inside smaller handguard.
Chamber is, for the first time in electric gun history, made of metal (as it appears to us), which might improve the hop up mechanism and will definitely improve the durability. There will be less wobble unlike in earlier SG550 and SG551. Motor has been changed to EG1000, the best in Marui series.
The folding stock has been reinforced from inside to make it more durable, while butt plate has been added for improved hold.
Handguard cap has been introduced for the first time to improve the authentic look of the gun and the shape of the cocking lever has been changed as well.
Interestingly, SG552 will have additional accessory which is new type of quick magazine loader that has been molded in the shape of pistol magazine.
The changes appear to be cosmetic at first in SG552 SEALS, but closer inspection reveal new electric gun which has new electric gun design features that were first started in G36C and are now featured in all Tokyo Marui new electric guns.
