In this Airsoft Spotlight, we will look at the Action Sport Games (ASG) Česká Zbrojovka (CZ) Scorpion Evo 3 A1 Airsoft Gun. We will also briefly review the history of ASG, CZ, and the lineage behind the CZ Scorpion. ActionSportGames is one of the top names in manufacturing replica firearms and airsoft accessories, including airsoft guns, airguns, Co2 guns, and replica firearms. They specialize in 1:1 scale replica guns and accessories licensed by numerous real firearm companies.
ASG was founded in April 2003 as a merger of the two largest Danish distributors of Airsoft Guns and accessories, Pedersen & Grobelnik A/S (founded 1992) and Vestergaard ApS (founded 1960), and they are currently based out of Humlebæk, Denmark. Česká Zbrojovka (CZ) is an old company that was established in 1936 out of a small town called Strakonice in the Czech Republic. Besides their extremely popular and well-known pistols, one of their more notable military weapons was the Škorpion vz. 61, which is what the new Scorpion Evo 3 A1 is loosely related to.
Above is a Škorpion variant, the Vz. 61 is chambered in 7.25x17mm (.32 ACP). Other variants have different model numbers chambered in calibers, like 9x17 (.380 Auto), 9x18 Makarov, and 9x19mm (9mm Luger). The gun is straight blowback (versus delayed blowback) and fires from a closed bolt. It is an awesome submachine gun. It is iconic and has been seen in the news and in numerous movies.
ASG has produced a faithful replica of the real CZ Scorpion Evo. The material they use to construct the body is like the actual Scorpion Evo. It is made of a nylon fiber-reinforced polymer, identical in all dimensions, and very close in weight. The technological advances in this gun are almost never ending. This is pushing the envelope for the quality and technology of an Airsoft Gun.
The gun features a 3-position stock fully adjustable for the length of pull (LOP). Speaking of LOP, the gun has a 12" LOP with the stock fully collapsed. With the stock in the fully extended position, the LOP is 14.06". This range should fit almost every shooter with and without bulky tactical vests.
The stock is also side folding and possibly one of the strongest folding stocks I have ever seen on an Airsoft Gun. The stock latch and mounting hardware are super burly. This has to do with it being made like the real stock on the real Scorpion Evo. With the stock folded, it makes for a super compact Personal Defense Weapon (PDW). While folded, the gun measures a MERE 17" Overall Length (OAL)! With the stock deployed and collapsed, the OAL is 24.75". I would take the suppressor off if we were going for a compact size. I replaced it with the ASG Metal Muzzle Brake.
I chose to run a HERA Arms HFG on this gun as the styling matches the lines of the Scorpion Evo beautifully. The gun also fits extremely securely on the rail and features a storage compartment at the bottom of the grip. They are also highly affordable.
I chose the ASG Super Xenon Weaponlight for this gun due to its compact size and bright output. The light uses two CR123A batteries, and the on-and-off switch's paddle design is intuitive when using the HERA Arms grip.
I used the suppressor most of the time and used the ASG Threaded Suppressor Adapter. This converts from the gun's 18mm threads to standard 14mm counterclockwise (CCW) threads. I attached the MadBull Licensed Gemtech Blackside. I could cover the longer inner barrel I opted to install.
To our surprise, the gun came with a 208mm 6.03mm polished brass tight bore barrel. However, we love to tinker with stuff and can't leave good enough alone. We opted to install an extended Fox Custom 363mm 6.02mm Stainless Steel tight bore barrel, which greatly increases barrel length for better accuracy and velocity. A 363mm long barrel is about the most I use with the stock cylinder volume, considering it is ported.
The hop-up unit is a lovely design. The adjustment for the hop-up is very positive, has satisfying clicks, and will not move unintentionally. The polymer feels extremely beefy, isn't soft, and is easily deformed when inserted into magazines. If you notice the shorter feed tube, this is made to work in combination with its magazines and feeds every round in the magazine. It is nice that you will not waste the last 4 to 5 rounds typical in M4 variants, especially when your magazines are 75 rounds. You can also see the 6.03mm brass factory tight bore barrel.
I prefer the Lancer Tactical Mini Red Dot sight for this gun. I chose this sight due to its low profile, lightweight, and integrated mounting base. It is also the proper height for a lower 1/3 co-witness sight picture. This means that when you aim through the iron sights (properly sighted in irons and optic), the red dot will appear aligned with the irons and sit on the front sight post.
This is a lower 1/3 co-witness and is my preferred sight picture for M4 variants and any I can achieve. It allows iron sights to be deployed all the time and does not block the sights' dot.
The picture above is the typical sight picture you would see and use with the sight still mounted on the same lower 1/3 co-witness setup. This still allows an unobstructed view of the sights dot. The nice thing about electronic dot sights is that the dot can be anywhere in the window, and you should still be able to hit the target.
However, parallax can cause aiming errors at close distances with all red dot sights when the dot is not centered in the electronic dot sight. However, this is usually negligible and is approximately 2" with lower-end electronic dot sights. The further the distance, the less parallax there is, and most sights that claim they are parallax-free are only so at, on average, 50 yards+—enough gibberish. Let's look at the guts of this thing.
For starters, the ASG CZ Scorpion EVO 3 gearbox features a quick change spring guide that is accessible without removing the gearbox from the body. You can change springs by folding the stock out of the way and removing the spring guide. The cylinder window looks slightly different than normal.
This gearbox cannot crack in the front like a standard version 2 gearbox shell. This is an ingenious approach to keeping the gearbox front from breaking off. On a typical gearbox shell, the cylinder would fit into a window cutout into the gearbox shell, which has 90-degree angles. As some of you may be aware, 90-degree angles have a lot of stress when the two angles meet, and from the constant pounding of the piston, a stress fracture can develop and ultimately break the entire front section off.
Some people add a small radius to any 90-degree angle to combat this, reducing the substantial stress. ASG has taken about 1000000 steps further, and the cylinder is fully encased into the shell, with no 90-degree ports cut. Also, the safety is on the selector plate and keeps the trigger from moving back. This eliminated the standard safety latch in a gearbox, further reducing the unnecessary stuff inside.
The selector plate is an entirely different design, and instead of actuating a cut-off lever there are a series of micro switches which control the ASCU Electronic trigger system.
Inside, ASG uses an Airsoft Systems ASCU explicitly designed for the Scorpion Evo. This is a fully electronic trigger and an airsoft MOSFET. The trigger travel and response are unmatched. The gun has an electronic semi and 3 3-round bursts. There are no cut-off levers or mechanical devices to wear out. ASCU MOSFET Trigger System is available for standard version 2 gearboxes to retrofit.
The gear set is of really lovely quality and rides in steel bushings. They are arranged in an excellent inline configuration.
The sector gear has a nice and big sector gear clip. Sector gear clips help ensure reliable feeding by delaying the loading cycle of the tappet plate. They keep the tappet plate open a little bit longer to allow more time for the BB to pop up and into position for the nozzle to take it home. It has no adverse side effects relating to velocity as it is closed well before the piston is released.
The piston is comparable to an aftermarket upgraded piston. The teeth are boxed in and fully supported on the sides compared to a standard piston, where the teeth are only attached at the base. The 2nd tooth is removed for better engagement with the sector gear. The piston features four metal teeth, which is ideal for half-metal teeth since it is lighter and acts as a built-in fuse for the system.
Typically, on an all-metal tooth piston setup, it is possible to destroy everything, including the gears and the piston, should one of the piston teeth break off or just wear out. The half-metal tooth varieties have extra strength, which is needed when the piston is pulled fully to the rear and under a big load. It also features a ported piston head, which should be the standard. As the piston goes forward, the air enters the ports on the face and expands the o-ring even tighter to the cylinder to increase the seal. There is no unnecessary drag or vacuum when the piston is retracted for the next shot.

Overall the Action Sport Games CZ Scorpion Evo is fairly priced and is an awesome value for all the stuff you get in this gun. Below is a typical breakdown of how to get a gun to a comparable level.
$300-400 - Proline Gun
$100 - ASCU
$50 - Tightbore Barrel
$100 - Upgraded Gearbox shell
$10 - Sector Gear Clip
$25 - Upgraded Piston and Piston Head
$585 to $685 in total, depending on the gun. It's a gun that won't feed every last round in the magazine or stop firing when you are out of ammo, not dry fire, or have a virtually indestructible gearbox shell.
I cannot stress enough how affordable this gun is and how much of a value it is at under $400.
