Great solution for saftey & accessibility

I don't have a long gun safe so I needed a way to secure my AR-15. The Chamber Lock was perfect. The AR is still accessibly but inoperable with the Chamber Lock securely in place. I had to change the combination to work better with my hand and if you watch the video it makes the process pretty simple. I did have to trouble shoot but the video even covered that. Just be very careful with the spings. I damaged one when reassembling and had to get a replacement. Samantha was great about sending several new spings. On that note prior to buying the lock I inquired about it fitment for my Daniel Defense DDM4 V7, since it was not listed on their site. Samantha was great about working with me until we determined it would fit. Great product and customer service.

It’s alright

I’m sure it works great for right side eject rifles. I have a left side eject and it still works it’s just really tight fitting. I would recommend it though even for lefties.

Chamber lock for the Ar-15

The lock works great, same concept as the stopbox, set your own code using your fingers. Construction is very sturdy and the lock is easy to use. Would definitely recommend to a friend.

Great Design!

This is a very well thought out product. It’s a very fast system yet also protects from unwanted hands. Highly recommend.

Too Small

Fits my conceal just fine, but my home protection pistol does not fit in the box so it’s ultimately useless
