Confirm the status of an unloaded chamber with Hoppe's Empty Chamber Flag 5-Pack. Chamber flags are made of a non-marring, safety-orange polymer that won't hurt your firearm or finish and give you visual and physical indication of an unloaded chamber. The chamber flag is inserted into the chamber of your unloaded firearm, and features a large flag-like flat that sticks out and is easily identifiable. Attached to the flag portion is an extended fabric piece for increased visibility. The inserted side even doubles as an AR-15 non-marring polymer punch. Add that additional layer of safety with the Hoppe's Empty Chamber Flag 5-Pack.
