Title: The Best Empty Chamber Flags
Review: I honestly didn’t know what to expect or have any grand expectations for these, but I needed at least one empty chamber flag that would work well and stay put. Many chamber flags are short, and unless you have some pressure on them, they fall out.This Chamber Flags solve that problem with there curved design. When inserted into the barrel of your gun, the curve applies some tension on the plastic flag and holds the flag in place. I swapped these out on all my riffles and shotguns and plan to buy some more. I drilled 1/4” holes in mine to add empty chamber indicators and the plastic took well to drilling through no problem, no signs of cracking or durability changes.Improvements could be keyring holes and offered in different colors and lengths.

Title: These pass the test of time
Review: I originally bought this type of bore flag because this is what came in the M1 I got from the CMP. Since then I’ve bought several other types, including the fabric ones that remind you to remove them before firing (good thing too, in case you forget and start firing BEFORE you remove it). Anyway, a trick I learned was to buy the rifle ones and cut them down to fit your pistols — saves money. Also, on a couple of my .22s I use just the fabric flags with the bolt closed on it. It doesn’t prove that there is nothing in the chamber, but it does show you’re trying to “indicate” an empty chamber.

Title: simply excellent
Review: it makes sense to have an ’empty chamber’ flag for the range or home.these are great.nice size flag.perfect for my needs.well priced.easy to bend extension that allows it to be used on just about anything and due to the extension they stay in place – rather than fall out like some of the shorter products.recommended.(i matched these up with the yellow ’empty chamber’ tags found here on amazon; they look great together)

Title: works as advertised, mostly.
Review: Easy to use and good value for the price. Only thing to note is it’s very rigid and has the square plastic piece located near the flag, this makes it hard to fit into a modern semiauto and the plastic piece wedges up against the extractor when you close the slide. I cut the plastic piece off and it closes better.

Title: Best Bang for the Buck Chamber Safety Flag on the market
Review: Best Bang for the Buck Chamber Safety Flag on the market that I could fine. They are functional and they fit all firearms I have seen to date, a great value for the $. As a Range Safety Officer trying to find a value added chamber safety flag solution for our range, I have purchased all the chamber safety flags available on Amazon and other sources. At ~$1.25 each they are a far greater value then the rest on the market. I wish they were closer to a $1 each because I’d like to make them economically available to all our range members. Certainly worth the price! My recommendation as the best value, highly functional, most versatile, won’t fall out when you move the firearm or be blown out by the wind. Chamber Checker

Title: Good simple empty chamber indicator
Review: I needed to trim the flag that sticks out the ejector port, to let the action close more fully, and the tip of the indicator show out the muzzle of a 4.5 in barrel. Would like the tip to be even longer, but this works.

Title: Great inexpensive safety device for piece of mind and courtesy to other shooters at the range.
Review: Work well in every firearm I’ve tried so far – Marlin 60 22LR, Saiga-12 shotgun, S&W 422 pistol, S&W k-frame revolvers, and Ruger Mini-30 rifle. I use them as a courtesy to other shooters at the range so that they can easily see that my chambers are empty when we head down range to change/inspect targets. I wish everyone would use them!They are also great for helping to teach new shooters the habit of clearing the chamber before setting a weapon down or handing it to another shooter.At the price, they are an absolute NO BRAINER to me!

Title: A most for all, some flexibility
Review: I think it’s better than the orange one. I would propose all U.S. firearm semi auto dales require this come in the box; It makes it all that much more safer.
