The product works, and work OK in a 5.56 chambered AR-15, better (but not perfect) in a .308 chambered AR-10 or a 300 blackout chambered AR-15, and probably would work great in a big bore rifle. Do NOT slam it home in the above mentioned firearms as it may get stuck.

Buy 10. Someone on the range is gonna need one.

What do you want? They're orange and sick in a chamber.

Great light great price and speedy delivery

What can you say about a chamber flag. It does the job it's designed to do.

...When they say "rifle", they mean it. It will *not* fit in a pistol. Very good for ARs and bolt-action rifles. I only use these at the range so that people *KNOW* it's unloaded. Very hefty little things. You won't question whether it's unloaded or not, as it will take up the entire chamber.

These are just plastic pieces that show your chamber is clear. If you go to any range when other people are there you should have one in. Its proper edicate/manners. One thing though, I ordered "new" but was clearly used. Dirty and covered in carbon and even had bolt markings from someone closing bolt on it. No big deal as its just plastic but annoying.

Good to have for visible safety with others around.

I like the fact that it was thicker than I thought it would be
