ASG CZ Scorpion EVO 3 A1 2020 Revision

The real steel Scorpion EVO 3 A1 has developed a massive following on the US Civilian tactical scene thanks to its combination of low cost and superb quality, riding the wave of the pistol calibre carbine trend which took the US by storm and resulted in many of the AR-9 platforms we all know and love today. The Scorpion EVO was originally designed for Law Enforcement and Military use as a Submachine Gun, and it currently serves with the Czech, Ukrainian and Canadian armed forces in both battlefield roles and law enforcement applications. 

The ASG Scorpion EVO is one of the most realistic electric Airsoft replicas available, boasting a uniquely designed gearbox with a “bolt stop” function, meaning when the magazine runs dry the SMG stops firing, requiring a swift reload and hitting the bolt release exactly like the real thing to get shooting again. The polymers used on ASG’s EVO are the same stuff the real thing is made from and are rock solid with a flat finish with a slight texture, indicative of fibre reinforcement. 

Starting at the front of the AEG we can find our Scorpion EVO birdcage style flash hider, matching the real EVO perfectly. This flash hider is constructed from aluminium with a satin gunmetal finish, and adds some nice visual interest to the EVO to give it a more realistic look. Beneath the flash hider is the barrel collar which holds the handguard on, and 18mm CCW male threading at the tip of the aluminium outer barrel. Obviously, everyone wants a tracer unit on their EVO for CQB domination, and this is easily done using the ASG Scorpion EVO Thread Adapter. 

The handguard is constructed from the same fantastic polymers used on the real CZ Scorpion EVO and is equipped with 20mm Picatinny rails at the 3, 6, 9 and 12 o'clock positions, providing a mounting point any 20mm Picatinny accessories you wish to add, including tactical flashlights, foregrips and other fancy do-dads. The upper 20mm Picatinny rail mates seamlessly with the receiver rail to allow optical sights of practically any length to be mounted, including red dot sight and magnifier combos, meaning even though the Scorpion EVO is a super compact platform you still have plenty of space to mount your mission essentials. The charging handle can be swapped to mount on either side, but is mounted on the left side as the EVO comes from the factory. Swapping the handle over is a simple affair, only requiring that the handguard is removed and the handle and its spring be swapped into the channel on the right side of the handguard. 

To access the battery compartment of the Scorpion EVO you will need to unscrew the flash hider and the barrel collar beneath, after which you can remove the handguard to access the battery compartment. The compartment is located inside the upper receiver and can fit a 7.4V 1300mAh LiPo stick battery with a Deans connector. The battery can be a bit of a fiddle to install but allows the EVO to keep its compact side folding stock setup and realistic shape and size. 

The receiver proudly displays its brand pedigree on the left side, with embossed trademarks reading “CZ Scorpion EVO 3 A1” which matches the real EVO perfectly. The controls of the EVO are all ambidextrous, with the magazine release taking the form of a paddle which is accessible with the trigger finger for both left and right-handed shooters and has a textured surface to make it easier to actuate during wet conditions. The bolt release catch is positioned on the left side and is also well within reach of the trigger finger, allowing for a fast reload despite the added complexity of this realistic operating method. 

The magazine well of the Scorpion EVO includes a slight flare on either side to help guide your magazine into the gun, minimising precise movements you need to carry out in the heat of battle and preventing a fumbled reload at a critical moment. The magazine catch is ambidextrous, with paddle style releases on either side, well within reach of the trigger finger. The benefit of the EVO's low profile paddle style mag release is that it is far more conformal to the shape of the weapon itself than other paddles found on AK and AR36 rifles which reduces the chances of snagging on equipment and causing the magazine to be dropped inadvertently. 

The fire selector has 4 positions with each mode indicated using a colour-coded dot pictogram. The modes available are safe, semi-automatic, 3-round burst and fully automatic, just like the real thing. The inclusion of the burst mode is one of the many things which makes the EVO stand out, as very few AEGs have a 4-position selector and burst mode without giving up full automatic in exchange. 

The EVO’s grip is an ergonomic design with linear texture on the front and rear to keep the SMG firmly in your hand during energetic sprints, and also has a palm rest at the bottom for added security. On either side, you will see a CZ logo roundel as you would find on the real Scorpion EVO. The grip is a slightly steeper angle than the average M4/AR15 grip but is very comfortable in combination with the EVO’s side folding retractable stock. 

The stock folding button is located on the left side, in the same spot as it is on similar folding stocked platforms such as the AR36 and folding stocked AK variants. The EVO stock folds to the right side and locks in place firmly, leaving you with a solid package with no wobble whatsoever, no matter how you choose to run the EVO in game. The stock is also adjustable for length of pull using the low profile adjustment lever at the toe of the stock and can be set up in one of any of the 5 positions of adjustment. This makes the EVO stock a step up from AR36 and AK folding stocks, allowing you to adjust the length to suit your loadout and body type. 

From a performance standpoint, we all should know by now, this is one of the best out of the box AEGs on the planet, and is still holding its own years after the first model was released with the latest versions boasting compatibility with Version 2 & 3 gearsets so if you want even more from your EVO it can take upgrades when needed. The inner barrel is a tightbore 6.03mm example, giving you awesome accuracy potential and slightly raised FPS which allows for higher power with reduced stress on the gearbox internals. The EVO also has ASG’s MOSFET pre-wired which will ensure the gearbox completes a full cycle with each trigger pull to prolong the life of the internals, and will automatically shut off if the voltage of your battery gets low enough to risk discharging it which is great for modern LiPo batteries. If you want a few more details on how this generation of EVO differs from previous models, check the Special Instructions section below.

So, if you demand a perfect hybrid of realism and performance with advanced features such as bolt stop and 3-round burst mode, the ASG Scorpion EVO would be the perfect thing. With a fantastic reputation for quality and performance married with an ultra slick modern design built from the same materials as the real thing, you cannot ask for much better straight out of the box than the ASG EVO!

Special Instructions

The sling loop on the handguard of the CZ Scorpion EVO 3 A1 2020 Revision has a tendency to fall out when the handguard is removed for battery installation. This allows it to be swapped to either side but can result in the sling point being lost if you aren't careful. 

EVO 2020 Revision Features

Performance Upgrades

Parts have been tweaked and tolerances improved to allow the replica to perform better.

Deans Battery Connector Upgrade

Revised steel cylinder

The weapon now includes a revised steel cylinder to improve the overall performance with a better air seal.

Cupped / Flanged Piston Head

ASG's latest piston head is included to improve performance and is cushioned to reduce impact on the gearbox.

2020 Revision Notes

This version of the Evo features slight tolerance changes to improve performance, as well as replacing the mini-tamiya battery connector with a higher quality deans connector.

2018 Revision Notes

Please note that the new cylinder set is compatible with other 3rd party Version 2 and Version 3 (M4/AK/G36) gearbox. All 2018 Revision specification parts are 100% inter-compatible with previous revisions.

Suppressor Attachment

To attach a suppressor you must purchase an 18mm to 14mm adaptor which are sold separately.

Battery Insertion

To insert the battery first unscrew the flash hider and barrel collar after which the hand guard can be removed. Please ensure that you hold the charging handle as it is spring ejected, as well as the forward sling mount point. When refitting the hand guard ensure the charging handle is placed in first, with the short end going in first.
