JTS MAR-12 rSS Build Kit

JTS MAR-12 rSS Build Kit

The JTS MAR-12 rSS Build Kit is an experimental hardware package designed specifically for compatible JTS 12-gauge platforms.

This is not a standard rSS installation. The JTS trigger geometry differs from a traditional setup, so proper fitting and modification of the JTS trigger is required for correct fit and function. A compatible Super Safety is required and is not included unless otherwise stated.

Kit Includes

• Rounded detent
• JTS bolt plug
• JTS lever sleeve
• JTS-specific lever
• Three-position trigger jig
• New buffer spacer — direct-fit design, tested for proper fit and function

Buffer Spacer

The included spacer is designed to work with the JTS buffer system to establish the required operating clearance and help prevent the lever from binding or jamming.

For best results, all mating and contact surfaces should be properly inspected and finished for smooth movement before use.

Important: This is an experimental builder's kit intended for experienced users. Proper fitment is critical. Professional installation is recommended if you are unfamiliar with the platform. Always verify compliance with applicable federal, state, and local laws before installation or use.
