Stack-On Stack On 18 Gun Beveled Edge Cabinet, GCM-1918-DX is rated 4.2 out of 5 by 76.
Rated 4 out of 5 by from Pretty nice cabinet for the price. This is a pretty nice looking cabinet and pretty easy to setup. Just remember this is a cabinet not a safe, it'll keep kids out quick smash and grab burglars but anyone determined to get in it will. Depending on type of guns kept in it 18 maybe optimistic if you have alot of rifles with pistol grips and magwells.

Rated 5 out of 5 by from Great storage Way better than the old steel cabinets, no plastic single shelf but actual steel shelving with the option to set it up to your liking

Rated 4 out of 5 by from Fantastic size for the price I searched high and low for a good sized cabinet that wouldn't break the bank. This one fit perfectly as it it was large, light enough for a single averaged size able bodies male to move when empty, and is customizable on the interior. The key only fits one way, which is the biggest negative I could come up with. While it is listed for 18 guns, if you add any of the shelves you are immediately down to at most 8 which you can see in the manufactures picture right off the bat. Assembly was not difficult, and if you are limber enough you can install everything on your own, but I recommend a helper. It took myself about an hour from start to finish, and the only "gotcha" moment I had was the center partition. Its shaped like this when looking at it from above: ̅ |_ with the holes for bolts on top and bottom. This means if you use the upper left hole to connect to the the top shelf, you will have to use the right hole on the floor of the unit, and I recommend installed the center partition and top shelf first and then the rear barrel rests as you wont be able to get the center partition installed if the barrel rests are already in place. There are 4 shelves two for each side, and if you use all four then you will only be able to store 4 rifles (two to left and right in front of shelves) in total. Each shelf includes pre cut foam, but the bottom foam piece is not cut which you will need a razer/scissors for. The top shelf does not go all the way to the back and there is a gap, and this is OK as that means the safe can fit longer barreled rifles without having to undo everything. Just remember that if you push items on the top shelf back as they may fall. When empty and unbolted to wall/floor (which it is pre-drilled for and bolts included) the unit feels a little wobbly due to the two bottom bolts attaching the center partition. The shelves are sturdy, and will not have any issues holding weight. There is plenty of room inside for ammunition, pistols, gear, and can even fit a smaller safe inside. This unit is not water proof, fire rated, have dead bolts, but it is still very well recommended.

Rated 1 out of 5 by from HORRIBLE I cant upload the pictures of the gun cabinet which is sketchy so dont trust this store. I bought mine for a decent price (now on sale for $40 cheaper) and the left side was burnt to a crisp. I drove an hour to pick it up not including the drive back. Brand new in the box so I wasnt going to drive a 2 hour round trip to take it back. The local store said they would take it back and sell me the display model since that's all they have left......?

Right out of the box, the door fell off like it was not attached on the right side (left side is locking mechanism). Am I missing something? How do I attach the door?

Asked by: Tyler1
Hello! Sometimes things shift in transit and the door might slide out of place. There's a small hole at the top and bottom of the door that fit into spring-loaded pins at the top and bottom of the cabinet body. The door will go back into place when the holes and pins are lined up. We'd love it if you could send photos to us at If the unit's door is still not closing properly, please contact us right away at 702-331-8033.
