The SI JCOMP Gen2 is the classic Type 89 compensator re-engineered and updated for the 21st century. Due to end user feedback, the favorite features of the original are retained, but the J Comp now features increased muzzle rise compensation, and is available in .308/7.62x51mm. Now also compatible with Oppressor and FerFrans concussion reduction devices.

• 3 Chamber design greatly increases recoil management.
• Hybrid muzzle brake/compensator.
• Pre-drilled for pinning and welding.
