Gsg-16 Upgrade Kit

[Kathleen Denson]

Thisitem is a set of genuine HK German factory push pins that will upgrade all your GSG-5 rifles or pistols to quick take-down push pins. This is one of the most common and desirable upgrades available for your GSG5 and a cheap, effective way to accessorize your GSG-5 rifles or pistols.

Please Note: The GSG5 will take the small hand guard or lower push pins without issue, but the large push pins require an easy modification by enlarging the opening through the buttstock to use the large push pin 9/32 or 7mm in diameter (takes only a few minutes). Our HK Genuine push pins come in black.

One issue is the plastic nubs sticking out the side of the handguard. Those are what the rail screws actually screw into. I would have preferred a slick sided handguard. I suppose if you do not want to ever use the rails you could shave those plastic nubs off.

The GSG-16 charging handle functions just like the MP5 but with an added bonus. You can now swap the handle to either side of the gun. You have to remove the top rail in order to access the screw that holds the charging handle in place. Once removed, you just swap the handle to the other side and reinstall the screw and top rail.

Taking a closer look at the GSG-16 top rail, there are iron sights and they are adjustable for elevation and windage. The only problem is that they sit extremely low so it will be difficult to cowitness a red dot. Another issue is that they are just made of polymer and are rather thin. They seem like they could be fragile and ATI send a spare set of screws and iron sights in case you break them.

At the rear of the GSG-16 is the strangest upgrade. The GSG-16 uses a collapsing stock. It is in the style of the H&K collapsing stock but has taken some liberties with artistic license. As you can see from the image below, the GSG-16 stock features a built-in spare magazine holder and a short Picatinny rail molded into the top of the stock.

On a serious side, I have a spare GSG-522 fixed stock that I picked up a couple years ago that I was planning on using for another project. It fits the GSG-16 perfectly and I prefer it over the collapsing stock.

The GSG-16 is a fun plinker. It has last round bolt hold open and you have to pull the charging handle to close the bolt. The GSG-16 also has a magazine safety so if the magazine is removed you cannot pull the trigger. It is compatible with all the GSG magazines like the drum mags and stick magazines. It is lightweight at just 5.84 lbs compared to its predecessor the GSG-522 at 6.6 lbs.

While the GSG-16 delivers everything I could want in a fun .22LR plinker the overall feel and finish of the housing leaves much to be desired. The entire gun is wrapped in plastic. Sure some of our most favorite guns are polymer like Glocks and CZ Scorpion Evo3. But the plastic used in the GSG-16 feels cheap and flimsy. I have felt airsoft guns that feel more robust than this. Not to say that the GSG-16 will break if you sneeze at it but the rails are hollow molded thin shells. They are held on to the housing with two small screws per rail. They flex a lot as does the housing. So do not expect rigidness for great accuracy.

The collapsing stock with integrated mag holder and Picatinny rail is pretty useless. Sure storing an extra mag is neat if you are going to ninja the mall but just like other magazine storing stocks, it is a gimmick. The old fixed stock is more solid and feels better to shoulder and shoot. The only real benefit I get from the collapsing stock is that it can fit into a smaller rifle bag.
