The 3D printed Mag Blok is a safety device to replace a chamber flag. Instead of inserting plastic into a hot chamber which can melt, the Mag Blok can be used on any AI AICS short action compatible DBM or chassis system to prevent the bolt from closing.

• Prevents bolt from closing

• Clearly visible in bright orange for range officers to clearly see the action is open and safe

Guaranteed compatibility with any AICS chassis mag well or DBM.

A custom logo can be placed in the Mag Block when you select the “Custom Logo” option. With this option, you can put your name, or send a DXF file containing the logo and a Mag Block will be made with your logo.
