WHY ARE WE GIVING AWAY A STOPBOX FOR FREE?

Yup. You read that right. We're giving our BEST SELLING product away for FREE, and here's why...

...WE WANT TO SHOOT 🔫 STRAIGHT WITH YOU -BUCKLE UP.

It's honestly very expensive 💸 to educate people on a product that's unique to the marketplace. Like shockingly 😱 expensive. The faster we go from introduction 👋 to lifetime customer 🫶 the less money Mark Zuckerberg gets to pocket off all of us. (That's not a joke!) So rather than tease you with a 10% off discount, then maybe a larger discount around the Holidays we're going to cut to the chase. Right here, right now. We'll give you a FREE StopBox when you purchase a Chamber Lock. That way you can secure your pistol with the same quick-access design as our Chamber Lock and we only have to pay for shipping once! It's truthfully that simple. Win-Win! 🙏

NO, THIS IS NOT 🚫 A SAFE.

We designed the Chamber Lock with this criteria: Instant, reliable access, in the dark and under stress, without the use of batteries or electronics.

✅ Also use as a Chamber Flag when ranges require it.

THE WHOLE ENCHILADA 🌯

The Chamber Lock is designed to prevent unintentional access while your firearm is at the ready. Our patented mechanical hand gesture code lock is instinctive to use in the dark and under stress.

  • VERY IMPRESSED

    ⭐⭐⭐⭐⭐

    Got the shotgun stopbox in yesterday and I think it’s great. I’m super impressed with how solid it feels, that rubber spacer was smart.
    I’m also impressed with how you can’t get the shells out of the top or bottom while it’s locked. Good product guys keep it up.

Love it.

I want another 12 guage chamber lock and an AR chamber lock. But, I can't afford it. Haha

These chamber locks are effin awesome. Do you have Kids? Family? Or just a busy household? These are fantastic and for you! The lock boxes are cool as well. YEA,They seem a bit jenky at first. Although! They do exactly what they're supposed to do, and thats a win win for advertising.
I must say it! I trust this analog chamber lock more than trigger guards. This set up over a digital, key or traditional combo entry is two thumbs up everytimee, it is as advertised. Got a 12 guage? Or and AR15? This is for you.

I wish stop box had a wider variety of boxes and chamber locks. Possibly even some trigger lock assemblies for pistols and smaller firearms. Sometimes, having a box on a table, is a bit too big. 5 out of 5 on both fronts. Thank you Stop Box.

Very Secure

Takes some practice but works well. I feel much better about having a loaded shotgun in my bedroom.
