Overview

The Redi-Catch MARS-L (Modular Ambidextrous Rifle Safety - Left) represents a significant ergonomic upgrade over standard AR-15 safety selectors, offering true ambidextrous operation with configurable throw angles. This safety selector allows shooters to choose between traditional 90-degree or short-throw 45-degree operation, dramatically improving weapon manipulation speed during transitions and ready positions.

The MARS-L features positive detent engagement at both 45 and 90-degree positions, ensuring crisp, tactile feedback that prevents accidental disengagement during dynamic movement. The ambidextrous design places controls on both sides of the lower receiver, allowing left-handed shooters to operate the safety naturally or giving right-handed shooters additional options for support-hand manipulation. The steel construction ensures durability under hard use while maintaining precise tolerances.

This safety selector has become increasingly popular in competition, defensive, and duty applications where speed and reliability are paramount. The short-throw option reduces the arc of movement required to transition from safe to fire, saving precious milliseconds during critical engagements. The modular design allows for different lever configurations to suit individual preferences and shooting styles.
