Excellent Value and Operation

Was looking for something that I could use to secure my nightstand piece (Canik TP9 Elite SC) and my wife’s 590 Cruiser that would make them easily accessible without being too difficult to get ready in a pinch in the dark. Enter StopboxUSA and the new shotgun lock and Stopbox. Great value and usability without breaking the bank. US company and that’s a huge plus. Very happy with both products. Shipped in 24 hours and was super easy to install and set up.

Safety for my pumpkin Mossberg

I thought it would be plasticky but it actually feels solid. Does what it was intended for and almost matched the orange furniture on my Halloween themed Mossberg. From now on this will be out of the safe, always be next to my bed and not worry about my child touching it.

Will address immediate needs; opportunities for improvements...

Received my AR-15 CL while I was out of state; finally had a chance try it out and set up for my platform. It took some work to understand where the block needed to be seated in the chamber area and to ensure the "lock" bar engaged the bolt carrier grove. I also worked to change the "code" to unlock/lock the CL; it is not fully intuitive how to remove the finger tabs and the first one went flying across the room. Got things take care of...
Now to where I think an improvement can come in. The AR-15 CL is hefty and seems to be well made; housing is made from aluminum (metal) and looks wonderful, this is the issue: that metal is slick. You need a firm grip on the device to engage the finger unlock combination; in the middle of the night when you hear that "bump in the night" I doubt your grip will be sufficient to disengage the device. I wrapped my CL in grip tape and it took care of that matter.
The next thing is that your chamber is left open to the environment; no way around this one as the CL must engage the bolt carrier area. I placed a glove over the open chamber.
Just my observations.
Overall, again this device is going to meet my needs at home; I have more "peace of mind" that my platform will not easily get used by someone not experienced in its operation.

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 .

Shot Gun Chamber Lock

While I was changing the combo, the thumb break (spring) got away from me. I was unable to locate same anywhere. I contacted Stop Box USA, they sent me three replacements in two days. Good to go, thanks again!
