GSG 522

The German Sport Guns GSG 522 is a great replica of the famous Heckler & Koch MP5. The MP5 has been around for a long time and still looks modern….it started in 1966! The MP5 has been used in SWAT teams in the USA and special military forces all over the world and come in all kinds of variations and caliber sizes.  They’ve also been in lots of movies because it’s one of the coolest looking sub machine guns ever created.

Here are the current options for the GSG 522

  GSG 522 Carbine  GSG 522 Carbine RS GSG 522 SD
 gsg 522  gsg 522 retractable stock  gsg 522 sd
 GSG 522 PK   GSG 522 P   GSG 522 SD RS
 gsg-522-PK-Version  gsg-522-P-Version  gsg-522-SD-RS

Sure everyone would love to own one and shoot one…however HK stopped making the civilian versions of the MP5 in the 1980’s which means to get a real HK select-fire 9mm MP5 will cost around $15,000-25,000. You also have to get some paper work filled with the ATF since it’s full auto. Even the quality replicas are over $1,500 – $2,500 (learn more about the original MP5).  Not to mention shooting 9mm rapid fire with a 25 round clip would get expensive fast. Each magazine you shoot would cost you at least $6-$8…shooting three magazines at the range would set you back at least $20.

Luckily several gun manufacture have been releasing great looking and great shooting replica machine guns (and handguns) chambered in .22 LR. There are a few reasons for this, first the .22 LR version are much cheaper then the full .223 or 9mm version. And secondly the .22 LR is much cheaper too shoot. .22 LR cost around $.05 to shoot verses $.50 plus for a .223 or 9mm at $.30.


Several of the top gun manufactures have created AR15 .22LR replicas and a couple have created a MP5 replica. Umarex makes a MP5 version that starts at $500 and is a great weapon. It has more metal parts then the GSG version but cost a lot more. But you’re not here because you want to know about those guns, you want to know more about the GSG 522.

Back in 2008 GSG started selling the 552 in a few different versions and it has been a very popular .22. There are the 522, 522 SD, and the MP5K and slight variations of each with different stocks, barrel lengths and accessories.

There is the 522 Carbine RS above with what looks like a sweet suppressor screwed on the end… unfortunately the sweet looking suppressor is fake due to a lot of reasons that include cost and regulations. The suppressor is just for looks on this version and they do offer a 522 without the suppressor if you like the look of that better. However in the USA if your rifle has stock the barrel has to be at least 16 inches long…so you can get the 522 without the suppressor and a shorter barrel, but it doesn’t come with a stock (you can illegally add on later if you want).

(GSG 522 P Version – short barrel without  a stock)

The magazines that come with it are very sturdy and like several of the high end replica .22 rifles the magazines are the same size as the real 9mm MP5 magazine so it adds to the realism and makes it great for military practice. Another nice perk of the realistic mags is that they’ll fit in all your gear.

They have magazines available in 3 different physical sizes and 5 different round capacities for various state laws.

There is a 22, 15, 10, 2 and a 110 drum round magazine! If you can find a 110 round drum they run around $90. Check them out here.

Shooting the rifle is a lot of fun, I was chewing through the cheap Winchester brick without too many issues. Once I figured out how the sites worked it was very accurate with the open sites and I plan on getting a red dot in the next few days and will do a full range report soon.

The trigger is smooth and light enough to keep it accurate.

It was fun shooting this at the range everyone can appreciate the look of the H&K MP5

GSG 522 Suppressors

The carbine and SD version have a mock suppressor on the barrel. The 522 P and 522 PK models have a threaded end and you can easily mount a suppressor on the P and PK models with an adapter. Unfortunately the carbine and SD models will require the barrel to be cut if you wanted to add a suppressor. So, if you want to add a silencer to your GSG 522 you’ll want to purchase the P or PK models.

 GSG 522 Accessories

Good news, there are a ton of accessories that fit these guns. There are all kinds of rails, tactical handguards, grips, bi-pods, SD conversion kits, over 6 different stocks, slings, flash hiders, silence adapters, different silencers, flip up sights and lots more. It’s a ton of fun to browse through all the accessories.

I have this gsg 522 sd and I have nothing but trouble with the factory mag. Do y’all know of a better made mag orbs matel mag???


Greg Fellows May 29, 2013 at 6:13 pm

I have the GSG 522 SD and I seem to have lost the magazine retaining spring to it. does anyone know where I can find another one?


jesse March 22, 2014 at 5:17 pm

i have the gsg 522 carbine and i was woundering if i can get a shorter barrel for it havent dont much looking yet just trying to speed it up a little if anyone know where i can get a shorter barrel please let me know thanks


gadmin April 3, 2014 at 2:39 pm

They don’t make shorter barrels. Plus, making the barrel shorter would make it a SBR and would require a $200 form from the ATF.


Todd March 23, 2014 at 10:24 pm

I just bought the CSG-522 SD. I’m looking for a tactical rail. One like in the picture above. I want the lower rail to mount a laser and flashlight, forgrip. If you know any Web sites that sell this let me know.


gadmin April 3, 2014 at 2:40 pm is the only one I know of. He modifies each rail to fit.


Chris June 19, 2014 at 11:47 am

Does anyone know of a replacement picatinny that is metal instead of the plastic? The plastic rail warps when you try to tighten down any sort of optic. I’ve heard there is a metal rail available for it but i haven’t been able to find it.



Fish July 2, 2014 at 1:53 pm

just installed this and seems, solid, nice and snug. Haven’t had a chance to test yet.


Fish July 7, 2014 at 12:24 pm

Just a quick follow-up:

When you remove the screws holding down the stock weaver rail on your GSG, DO NOT REINSERT THEM until you cut them down. If you reinsert the screws as-is, they will protrude into the upper receiver and block the cocking tube, making it impossible to pull the charging handle back.


Chris July 7, 2014 at 1:10 pm

So essentially pulling off the stock plastic rail and replacing it with the clamp on rail… let me know how it works, not ideal, but might be an option…


Fish August 13, 2014 at 11:41 am

Yes, it’s worked out fine. 300 rounds through without issue.
I recommend checking the screws for tightness occasionally, but I haven’t had an issue with them yet.


Pitt June 30, 2014 at 10:32 pm

I’ve been unable to determine how/where the shrouds attach.
Is it possible to thread the barrel, open up the end of the fake suppressor and then screw a can onto the threaded barrel and have it extend out the end of the fake shroud.
Is the only difference between the lightweight and other model just that the receiver is plastic/ polymer. ??
Does that create any issues other than clamping a sight rail to a plastic top??
Can u polish up the triggers some?
Collapsible stock solid when it’s out and locked in?


Pitt June 30, 2014 at 10:57 pm

Also which seem to be more popular after handling?
The lightweight with tapered forearm and skinny shroud?
The regular weight with large round ribbed forearm and large diameter shroud?
Retractable stock or fixed stock?
I’ll be buying sight unseen thru a dealer and I’ve never handled one so your input is VERY much appreciated.


gadmin July 7, 2014 at 12:32 pm

The most popular is the lightweight standard model with the tapered front. Probably because it’s the cheapest. It’s hard to find one with the retractable stock on it already. You can buy the retractable stock at just about anytime. However the retractable stocks are only imported from Germany a couple/few times per year and dealers seem to run out randomly throughout the year…so if it’s hard to find a retract stock now you’ll probably be able to find them in a few months….they’re probably sold out and waiting until the next shipment comes in.

I own a gsg 522 sd and I’ve ordered a few rails for it and none of them will fit the mounting holes never line up any suggestions?


Travis December 18, 2014 at 9:36 am

Are you talking about the front foregrip rails? I think the one from ultimate arms fits.
Or you can take the one the guy at rrages spends 2 hours modifying to fit…not cheap because of his time and the cost of the rail but it fits and looks awesome. his website >


Ben lash December 24, 2014 at 10:51 pm

Well I just listened to this forum and it was a mistake with the following

The second more aggressive 522 tactical rail is this for sale right now at Amazon. The Ultimate Arms Gear Tactical Aluminum 3 Tri Weaver Picatinny Rail. I’m not sure why this thing is so cheap but it’s a super deal right now for under $40.

God I wish I could attach pictures.. It will not fit. It won’t fit on the gun nor will it take a mag pul atg mag pul grip..


Jeff January 8, 2015 at 10:26 pm

I have a rather simple question nhere and I hope someone can give me a simple answer.

I just bought a GSG 522 SD RT and was wanting to set it up like that lovely GSG Catbinne pictured above with the Tactical Tri-Rail Handguard with the Grip and Laser. I have purchased the genuine MP5 Conversion Kit for the proper front Sight, Charging Handle and reciever cover but have yet to attempt to remove the original parts to do the conversion and wish to do the all the exchanges at the same time. My question is this: will the larger Faux Suppressor of the GSG 522 SD RT insert and lock safely without having to buy some sort of adapter or will I need to get the Faux Suppressor for the GSG 522 Carbine?

I have contacted ATI numerouss times via Email and by filling out the form on their Website but they do not send any replies. Any help from a GSG Guru would be greatly appreciated!

SGT. AJ Harman


Travis January 9, 2015 at 5:45 pm

Jeff, I honestly don’t know. I think it will fit because the faux suppressor is out in front. I’d say give it a shot 😉


bailey February 11, 2015 at 12:56 am

I was wondering if the 110 round drum compatible with the m4 22lr ATI AR 15 style rifle?


Travis February 11, 2015 at 7:40 am

Nope, the GSG 522 drum ONLY fits the GSG 522 rifles and GSG 522 pistol versions.
