What is the CHAMBER SAFE, INC. - Chamber Blocking Device, 223 Remington and Larger?

CHAMBER SAFE CHAMBER BLOCKING DEVICE

Bright orange chamber blocker fits in the ejection port and physically prevents chambering of a round to provide positive visual confirmation that the firearm is unloaded. Removes instantly by pulling the large, easy-to-grasp ring to clear the chamber and bring the weapon into operation. Use in any situation that requires fast, visual verification of firearm status—law enforcement, military, gun shops, as well as hunting, range, and competition applications. Fits semi- and full-auto rifles and carbines with an extractor enclosed within the bolt, including AR-15/M16/M4 and M14/M1A. Flexible, one-piece, molded polymer construction stands up to years of insertion and removal cycles. Tab on pull ring allows marking with individual weapon identification information. SPECS: Molded polymer, orange. Fits AR-15/M16, M14/M1A, and other semi- and full-auto rifles and carbines with extractor enclosed within the bolt. Should not be used on any firearm with an extractor that extends forward from the bolt.

Great product ! Highly recommended !

This came highly recommended by our Ranger Master. It is super easy to grab, easy to remove and install chamber flag, or empty chamber indicator device. It won’t break, even if you slam the bolt on it. It won’t cause any damage to the bolt or chamber. Great product !

Would you recommend this? Yes, I would recommend to a friend

The Best

Having a block that you can remove in a split second... None other provides this function! Simple and sets a safety standard in your whole house of rifles.

Easy to see and holds up well.

I have been using this device for several years now and I am still using the original one I was issued. They hold up to AR bolts being slammed on them no matter how hot or cold the chamber blocking device is. There have been no pieces flaking off into the bolt or chamber no matter how many times the device has been used either. These are mandatory devices for our patrol rifles because perfect muzzle discipline is not always possible inside a police station but I can tell at a glance that the weapon is not loaded and safe. Highly recommended.

I'm sold and I hope you are too.

Jeff Chudwin sent me some when they first came out and I've been an advocate of its worth ever since. I use them for all the long gun classes I teach including Patrol Rifle Instructor, Tactical Weapons Opeartor and the SWAT Academy. I encourage students to take this to their departments as a way to enhance the safety of their firearms training. The feedback I've gotten back from them is that not only do they work great on the range but also with field deployment.

Practical, easy to use.

I was issued my first Chambersafe by my Department when I was issued my patrol rifle(AR-15), and have incorporated them into all of the rifle classes I teach. When officers are switching cars in the parking lot or loading gear into a squad from a personal car, anyone nearby can see the Chambersafe and know the condition of the rifle, but to deploy with it is fast, simply rip it out, no other manipulation is required. Once the shooting line has been made cold, it is an excellent visual for instructors or safety officers since it actually inserts into the chamber, instead of the old rope trick that just indicates an empty magwell. The fact that it can be used on duty, off duty, training, and required no manipulation to deploy makes it a winner in my book.
