If you want the classic MP5 look then you'll want to get this great GSG 522 retractable stock. While the GSG 522 looks great with the original fixed position stock, the 522 collapsible stock gives it a more tactical look and offers a more compact foot print for the gun. This is a high quality all metal retractable stock from the GSG factory.
GSG does sell a version of the GSG 522 rifles with the retractable stock already installed...however these are hard to find for whatever reason. The good news is that they sell the GSG 522 collapsible stock to retailers like us at a great price and that means we can sell them at an incredible low price for a perfect fitting retractable stock for GSG 522. Most stocks are $75+ for just about any gun, but you can get this baby for under $60.
This is a all metal collapsible stock from GSG made for the GSG 522 and GSG 5. It has 4 positions and will not slide off the gun if you over extend it (some of the cheaper plastic airsoft stocks will slide off the gun if you extend it too far).
With the collapsible stock on your GSG 522 you can fit it in a backpack or much shorter bag.
Installation is incredibly easy and takes about 30 seconds.
Simply remove the screw on the current stock and pull the stock off. Insert the new GSG 5 retractable stock on and it will line up perfectly with the screw hole. Simply insert the same screw and tighten down.
Does this GSG stock fit the Umarex H&K MP5?
No, this is a factory made GSG 522 retractable stock for the GSG 522 only. It does not fit the Umarex version.
Does this GSG 522 retractable stock cover the ejection port?
Noway! This stock is perfectly made for all of the GSG 522 guns and the GSG 5 and only improves the gun.
Does this GSG 522 retractable stock have a metal endcap?
Yes, this is the latest version that is all metal.
