• The IASC9 integral suppressor is for the NEXUS G1 EVO and the CZ Scorpion EVO S1, S2, and 3 Plus. You can use it on the Scorpion Micro, However, the factory barrel is too short and you will not be able to send it in for the integral modification. You will need to order an aftermarket barrel as part of our kit when you order, or you may purchase one directly through the manufacturer. 
• This suppressor is offered in two sizes. The IASC9 (standard length) and the IASC9-K (micro size).
• The IA-SC9 is not a modular suppressor.
• Adding a stock to the integral firearm will make it a short-barreled rifle, and all NFA rules for SBR firearms will apply.  
• Not only is it BAD TO THE BONE but it’s smoking hot too! We recommend using gloves or the heat shield. The heat shield is available when you order or you can order it separately at this link.
• A specific HBI flat 6.84″ anodized handguard (complete kit) is required for fit and function. It is available when you order, or you can order it directly from the manufacturer at this link. *We are not affiliated with HBI in any form.
• The usable M-LOK interface points are limited. For the IASC9 8.2″ silencer, all lower M-LOK slots may be used, as well as one rearward slot on each side of the handguard where no silencer cups are present. For the IASC9-K (small) silencer, only the lower slots are available. When the heat shield is installed with the IASC9-K, the two side slots integrated into the heat shield also become available for use.
• This integral gives subsonic velocities with high-velocity ammunition.
• If you are supplying the barrel it must have at least a 4″ long for the IASC9-K (micro size) and 5″ long for the IASC9 (standard size).
• The integral is user-serviceable.
• A disassembly tool is included.
  
• Full auto rated
• The barrel of the CZ Scorpion 3 plus is difficult to remove. You may require a tool from HB Industries or you may opt to send your complete 3 Plus firearm to us for professional installation. 

THERE ARE TWO DIFFERENT SIZE MODELS OF THIS SILENCER.

The IASC9 integral suppressor is for the NEXUS G1 EVO and the CZ Scorpion EVO S1, S2, and 3 Plus and is offered in two sizes.

The difference between the two sizes are length, heat and a 2DB sound difference. The “K” size will be shorter, hotter and 2 DB louder than the standard size. 

Cleaning and Maintenance Instructions for the Integral IASC9 and IASC9-K Suppressor

1. Cleaning Frequency
   • The Integral suppressor requires minimal maintenance.
   • Clean at least every 500 rounds and/or when you can shake the firearm and hear unburnt powder, lead, or debris moving inside (similar to a sand-like sound).
2. Cleaning the Core
   • The core is made of 17-4 PH stainless steel.
   • You may use any gun cleaner of your choice on the core.
3. Cleaning the Cups
   • The cups are made of Type 3 hardcoat anodized 6061 aluminum.
   • Only use a non-ammonia-based cleaner to avoid damage.
4. Reassembly After Cleaning
   • Apply a light coat of dielectric grease where the cups contact each other, as well as on the core and barrel threads.
   • Use the provided tool to tighten the suppressor against the barrel shoulder.
   • No torque specifications are required—when the suppressor shoulders against the barrel, proper bore alignment and cup sealing will be achieved.
