Chamber-View Empty Chamber Indicators (ECIs) for shotguns, AR/AK-Type rifles and semi-auto pistols are available in a variety of colors and styles for special requests and customization. The Chamber-View ECIs can be tailored to an organizations preference with an expansive range of colors or can be made into a private label for firearm manufacturers, scholastic and youth programs, law enforcement training, new shooter programs, shooting preserves and ranges, hunting clubs and special events, programs and competitions.
Made of 100% silicone, the Chamber-View ECI provides instant recognition that a firearm is safe by indicating a fully open action to surrounding shooters, personnel and observers. Not only does it enhance the safety of the shooter by aiding against accidental closings of the action, the Chamber-View ECI also helps preserve firearm performance by preventing elements from contaminating the ejector port, magazine and barrel.
