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.- Lance
