This guide details the installation of the Innovative Arms IA-SC9 integrally suppressed barrel and suppressor system for the CZ Scorpion EVO. It covers the basic steps of replacing the factory barrel and handguard with the IA-SC9 components. The video emphasizes the system's ability to reduce supersonic 9mm ammunition to subsonic velocities using a ported barrel design, as demonstrated by expert Tim from Military Arms Channel.

Quick Summary

The Innovative Arms IA-SC9 integrally suppressed CZ Scorpion EVO utilizes a 4.8-inch ported barrel to reduce standard 9mm supersonic ammunition to subsonic velocities, effectively eliminating the sonic crack. While muzzle decibel readings are low (121-127 dB), shooter's ear readings are higher (136-141 dB) due to action noise. The kit costs $725 plus a $200 NFA tax stamp.

Frequently Asked Questions

How does the Innovative Arms IA-SC9 make 9mm ammo subsonic?

The IA-SC9 uses a 4.8-inch ported barrel. These ports bleed off gas pressure, slowing supersonic 9mm rounds like 115gr and 124gr down to subsonic speeds before they enter the suppressor, eliminating the sonic crack.

What are the sound levels of the IA-SC9?

Muzzle readings are very low, around 121-127 dB. However, at the shooter's ear, levels are higher (136-141 dB) due to the CZ Scorpion's blowback action noise and 'port pop'.

What is the cost of the Innovative Arms IA-SC9?

The IA-SC9 suppressor and barrel kit costs $725. A complete firearm package is available for $1750. Both require a $200 NFA tax stamp.

Is the IA-SC9 compatible with standard 9mm ammunition?

Yes, a key feature of the IA-SC9 is its ability to slow down standard supersonic 9mm ammunition (115gr and 124gr) to subsonic velocities, meaning specialized subsonic ammo isn't strictly required for quiet operation.
