Lefty compatible

I'm one of those weird left-handed people. Main question in buying was, could I use this on my lefty AR. Answer I got was, "It should".....well, it does. Recommend adjusting the combo as it can be a little less than smooth than advertised but I have it set where I can use either hand to disengage. Excited to have this as I have children in the house and feel that this is a better platform for home defense than my pistol but harder to secure and deploy. Problem solved.

Glad your Chamber Lock is working for you! We usually answer with 'should' as many firearms are easily modified or a variety that may not be compatible.

Mossberg Shockwave Home Defense

I have been configuring my mossberg shockwave as a home defense option for quite some time. One of the issues I have had with the shotgun platform is the lack of a drop safety which is easily solved by not chambering a round. However, I also wanted a way to secure my firearm for staging. The stopbox Chamberlock perfectly solves my problems. I feel that I am more comfortable leaving rounds in the tube and stored safely. Let’s pray I never need to unload a tube of minishells in my home!

Love It!!!

Love the Chamber Lock!! Would HIGHLY recommend including an extra spring in the box - Finally found mine after if sprung across the room while changing Finger Lock Code. Also Highly recommend watching the Instructional Video before dis-assembly. Thanks!!

More grease in the cogs!

My dad loves the box, and I am rock in the chamber luck... always quality material, my only suggestion is more lubricant between the plastic parts... I’ve had to use more lubricant to make everything smooth in the box, but once I did then everything is smooth.
