ChamberSnake for 10mm : 12-1/2″ (32cm) Extension

ChamberSnake is the ORIGINAL Chamber Safe Indicator (CSI). This durable, patented, nylon chamber blocker features a bright “Electricity Yellow” strip that extends out of your rifles muzzle to provide immediate visual confirmation that the firearm is positively unloaded and safe.

ChamberSnake designed to fit perfectly into the chamber of your 10mm (.400˝) firearm, allowing you to cycle and dry-fire your weapon. The 12-1/2″ (32cm) extension is long enough to protrude out of the end of the gun and flexible enough to bend so the gun can be holstered or stored in its case.

Use ChamberSnake in conjunction with your trigger lock to ensure that your gun is secure AND safely unloaded.

Perfect for your Heckler & Koch MP5/10, or any other Submachine gun that uses a 10mm cartridge.


Made of high quality 6/6 Nylon plastic

Positive visual safety confirmation of an empty chamber

Excellent abrasion resistance; Extremely durable

Resists fading from exposure to sunlight or elements
