Question: Will this still work if I have a six-shell holder mounted on my Remington 870?
Document: I bought this for my Mossberg 500 with top rail and 4 shell side holder, so this did not work for me but is a nice wall mounted lock box for a shotgun. Would have been nice if it would have worked.
My Mossberg 590 has a light mounted on slide forward and offset to the left. I installed the Loc-Box vertically and had no problems. (the Loc-box puts the right side of the gun toward the wall.)
very tight fit with a mossberg M590A1 with a heatshield and ghost ring sights. If you have a side saddle on your gun or if you have a light on the right side, its not gonna close and lock. It is not ambidextrous, it will only fit shotguns with the shell/ejector port on the right side, and you can't flip it 180degrees if you wanted too...
Mount the box and the heavy-duty rod to a vertical wall stud with long screws. To use, slip the gun barrel up around the rod with the stock positioned in the box. Close the box and lock. The gun absolutely can't go anywhere. Very safe. Of course, you'll still need to hide the key from the little ones.
waste of money. I can't use it for its intended purpose. what do I do with this piece of potmetal?
If an intruder breaks in, I can arm myself with my pistol, grab the key for the Loc-Box and unlock the real home defense weapon!
Great wall mount, very easy to install and secure. Now I have quick access to my Mossberg 5901 Combat pump. Zombies beware.
Knowing the zombie apocalypse could spring at any moment, I installed the Mossberg Lock Box near my headboard (Rem870HD with Houge Overmold and Elzetta Light setup).Very well made and mounts very easily.
This item is as advertised. It secures a single shotgun. I am using it for my Mossberg 500 with security 18.5 inch barrel. In order to install it you need to make sure you are over a stud. With the long screws in secures pretty well and would be difficult to remove, requiring tools.
Sometimes you want to have the security of a shotgun at the ready, but these days you can't just leave a firearm loaded and leaning against the wall or tucked away in your closet.This is the happy medium. My shotgun is locked up, so unauthorized hands can't tinker with it, and if I need it fast, I just use the key and unlock the lock.
Answer: yes
