The Airborne Arms Stinger CZ Scorpion Handguard is compatible with the Evo 3 Plus. Installing the handguard will require you to remove your barrel nut in order to slide off the OEM handguard. A barrel nut wrench/socket will be needed. I would recommend the Midwest Industries CZ Scorpion Pistol Barrel Nut Socket, which can be found by using the link below:

The Airborne Arms Stinger CZ Scorpion Handguard will work with the Scorpion 3 Plus Micro.
Yes. The Airborne Arms Stinger CZ Scorpion Handguard is designed specifically for the CZ Scorpion EVO S1. Keep in mind, the Handguard CANNOT be used on barrels with permanently attached muzzle devices (3 lug, ASR, Etc). Any muzzle device would need to be removed to install the trunnion clamp. A polymer charging handle is recommended to avoid metal on metal contact between the charging handle and handguard.
Unfortunately we do not currently carry barrels for the CZ Scorpion. As for handguards, it mostly comes down to preference and price. On my personal EVO, I use the Midwest industries Handguard because I like its simplicity and lightness. The Airborne Arms Stinger CZ Scorpion Handguard is unique because it uses a hexagonal shape to allow for a more ergonomic grip on the weapon. Strike Industries also has their own handguard that offers MLOK compatibility and includes a faux suppressor to improve the overall look of the pistol. It mostly comes down to the features, looks and price and only you can decide what you would like to use on your gun. Links to the Midwest and Strike Industries handguards can be found below.
