Description
The Mag Safety Block is designed to be inserted into an AR15-patterned mag well to show a rifle’s status. It was designed to provide an extra level of safety while conducting CQB training, during competition matches, or while transporting the rifle. This training aid helps the students get a realistic rep while dry practicing and gives instructors a visual aid to know a rifle’s status from a distance.
- “CLEAR” Markings are visible through the ejection port door while the port door is open.
- The MagBlock holds the bolt to the rear locked position as well as prevents the bolt from being seated forward while inserted.
- GLOW GREEN & GLOW BLUE color shows inert mags.
* Note: Please ensure all rifles are unloaded and clear before the mag block is inserted. VEIL Solutions & Flatline Fiber Co does not take responsibility for improper use.*
Our gear is proudly manufactured in-house by our team. Because each order is made with care and attention to quality, orders typically ship within **5–7 business days**.

IT FRIGGIN GLOWS IN THE DARK.
Neat 3d printed mag block, feels sturdy while not being heavy. Says clear through the dust cover- the block pushes up on the hold open so the bolt can’t be dropped on it. 5 stars yo

I love this chamber flag more than any others I have used. It corrects a lot of the downsides to other clear chamber indicators such as preventing the bolt from being forward and also nothing being stuck in a hot chamber to break off during matches or training. I did take mine and color filled the CLEAR lettering with paint to make it stand out even more since some RO’s thought it was a mag in the gun while on the rack at matches.
