Bull Craft Industries AR-15 / M4 Empty Rifle Chamber Block
Make cold-range safety easy to see with the Bull Craft Industries AR-15 / M4 Empty Rifle Chamber Block. Designed for .223/5.56 AR-15 and M4-style rifles, this block provides quick visual confirmation that the rifle has been rendered safe — making life easier for shooters and RSOs when the range goes cold.
Made from high-heat-resistant material, it is designed to handle freshly fired rifles and long days at the range without warping or melting.
The block installs through the magazine well with the bolt locked to the rear, creating an obvious visual indicator that the rifle has been cleared. Its extended bottom also acts as a support base, allowing the rifle to sit upright when installed.
The standard version is dyed black, but the material takes paint well if you want a brighter, high-visibility color. Undyed grey is available by request for easier custom painting.
