A perfect fit!

My family has a 12 gauge pump that we keep from defense. With my young kids starting to get curious, we were worried, but with the chamber lock, both of us adults can easily access it in an emergency, and we are confident that our kids will not be able to hurt themselves or others with it. A lock is no replacement for good training, but it's always good to have a backup.

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.
