Review: good product - durable and easy to use
Review: Excellent Product For A Good Price - My AR-15 came with a yellow chamber safety flag, which I used constantly, switching it to whatever semi-auto I happen to be using at the time. I've been wanting more but the yellow ones like I had are ridiculously expensive. Found a set of these orange Monstrum flags for a good price and now have one in every semi to demonstrate an empty chamber. They're functional, obvious and cost effective. I liked them so much, I bought a set for each person on my deer lease as a Christmas present.

### ⭐⭐⭐⭐⭐ Excellent Product For A Good Price

### ⭐⭐⭐⭐⭐ Simple and great
*by S***N on May 26, 2019*

These work great as designed for being a chamber indicator. Later I learned they have a flat head slot so adjusting scopes or minorly tightening things works great. Being able to attach a key ring and flag only increases visibility from range officials. They easily slide onto rails for ease of access when needed. I continue to enjoy using and promoting these. Fits well in all my AR platforms, most pistols, shotguns, and a couple of bolt guns. I will be back to get more when needed and definitely recomend them.
