Stack-On is one of the oldest gun safe manufacturers in the USA and have had a wild ride over the last 12 years. Starting in 2014 they were still headquartered in and producing safes in Illinois, they then were acquired by Cannon and moved to Henderson, Nevada for a better business environment and no state taxes and eventually moved all manufacturing to Mexico and China for cheaper labor costs and low tariffs. So to answer the original question, is Stack-On made in USA? No, they are not and are made in Mexico and China. Just because something is not made in USA doesn’t necessarily mean it is not good quality, however when it comes to Stack-On, the safes actually aren’t that good. Let’s go over what features are good and what features are bad when it comes to Stack-On Gun Safes.
Lock
Stack-On primarily exclusively uses the standard Chinese solenoid lock found on Sports Afield, Winchester TS, and nearly every other low end imported gun safe from China. This is a very low quality lock that comes with a key override so that you can still get into the safe when the lock inevitably fails. It is nearly impossible to swap the lock out to a UL Rated lock due to the footprint and mounting style the Solenoid lock requires. I would highly recommend staying as far away from these locks as possible.
Security
Stack-On safes are not high security by any means and only are tested for CA DOJ firearm safety device. This is the lowest security rating possible and is required when safes are thinner than 12 gauge. Stack-On makes nearly all of their gun safes 14 gauge with the cheapest ones being 16 gauge. This is a steel thickness that is thin even for a pistol box and you are likely to end up with dents just from scratching or lightly hitting the safe. Saws can cut through this like butter and I strongly recommend purchasing a gun safe with a minimum of 12 gauge steel and a UL RSC Burglary Rating. You won’t find that from Stack-On safes.
Fire Rating
Stack-On does not test their fire ratings from an independent laboratory like Cannon. Because 90% of their products are imported from China, they just list it as factory tested but the safes never actually were tested in a fire so it is impossible to know their true rating. This is dangerous and I would not recommend Stack-On to survive in the standard house fire.
The Bottom Line
Is Stack-On made in USA? No, they are not. Are they still good quality even though they are made in Mexico and China? I would also say no. The steel is thin, lock is crap, fire rating is unreliable and there are just so many better options available from American Security, Liberty, Rhino, Remington and Stealth. The bottom line here is I would avoid a cheap Stack-On gun safe and go with a better brand.
