AR15 + STOPBOX

My girlfriend bought me a stopbox for Christmas and I really liked the convenience and security of it, so when I seen the deal for the AR 15 chamber lock and a stopbox I couldn't pass up the offer. Recently got an AR 15 so boom jumped on it and the fact that it came with the extra stopbox was perfect because I wanted to get my girlfriend one for her gun. Really digging the purchase definitely recommend.

That's awesome Jose! We're very glad to hear that. :)

Works Perfect

I invested in this product to help keep my family safe for multiple reasons. I wanted something that could lock my AR with while keeping it in a concealed wall art cabinet and not have to worry if my kids found it. And then getting the StopBox as part of the AR 15 lock purchase, gives me the peace of mind that I can keep my handgun on our headboard for easy access.

That's awesome! Thanks for sharing a review, Jonathon.

Keeping curious hands safe.

What I expected/hoped for. The AR lock comes off in a second with very little practice, but is secure enough to prevent little hands from accessing it if they find it. Same for the box. Neither are a safe, but they aren't supposed to be, they are however fantastic at preventing little hands from causing a potentially tragic accident. My only complaint is the cost. 150 for the AR lock seems about 50 dollars more expensive than what I would consider a good deal. Thankfully I picked it up with the free Stop Box, which felt like a decent value. Overall very happy with the products, but I hope y'all plan on doing some things to provide these safety tools to folks that don't have the benefit of an income that allows for such costs.

Required Modification to Fit

The shotgun chamber lock did not fit my 12 ga. pump shotgun out of the box. I had to cut the rubber gasket (reduce the width) in order for the device to properly lock into place when inserted into the chamber. After doing that, it works as advertised.

However, I found the method to change the lock combination very tedious and felt like I had to come close to breaking the plastic pieces in order to remove them.

Overall I am glad I was able to make it work, but not sure if its function and quality of product justify the price. If the chamber lock had not come with a free stop box, I likely would have returned it.

Hey Daniel,

Thank you for your feedback! Our products are not going to fit every firearm perfectly due to variances by manufacturers, but I'm happy you were able to make it work!

Great concept, great product, excellent customer service

First, this is not a gun safe and Stopbox made it clear, they have been fully transparent. This is a retention device that allows you instant access, every time without any worries of malfunction due to battery issues. I educated myself on the product and reviewed lots of comments in different websites, I looked at all pro and cons before placing my order. I got both, chamber box and Stopbox, and I couldn’t be happier. I had a small issue with my shipment and Mr. Edwards from the stopbox took care of it in a timely manner, I was extremely impressed with their professionalism, another reason to make me feel more confident with the product.

I am sure the team is looking into a steel or aluminum version of the stopbox, I can’t wait for it. This is a great concept and you won’t be disappointed. Thank you Stopbox.
