American Range Systems makes bullet traps for shooting ranges. But their bullet traps are not just for ranges. They are used by manufacturers, importers and anyone who tests firearms. Their latest weapon testing system is this large Coffin sized container which is humorously named The Coffin.

The Coffin was developed after user feedback. One of the owner’s customer’s imported over 100k surplus firearms and before selling them he had them function tested by firing three rounds. Well one of these firearms had an obstruction in the barrel before they even tested them. I do not know why they did not inspect each firearm but I can understand the sheer number of firearms to get through that sometimes things slip past inspection. They fired this firearm and had a catastrophic failure. Luckily no one was hurt. Because of this incident American Range Systems developed an enclosed test firing rig, and the Coffin was born.

The Coffin is made of 1″ thick AR500 steel and according to the maker, it can contain a catastrophic failure even from a .50BMG. The handles that run along the side are merely for aesthetics and to give it more of a coffin look. The door has a bullet proof window the same thickness as the ones found on Humvees.

Inside the coffin is a rifle rest that is adjustable for all manner of firearms. The sled sits on rails and has springs to dampen the recoil.

The inlet to the bullet trap just holds the barrel and minimizes gasses backing into the gun chamber. However if the rifle you are using has a large muzzle brake, you can remove the foam insert.

The rear of the Coffin contains the bullet trap. You can open it to swap out the containers of medium once it has been shot too many times. One small issue is that since the firearms are held in relatively the same position every time, the bullets will impact the same spot over and over again. This will greatly reduce the lifespan of the bullet trap. On top of the coffin is a hepa filter but they recommend getting a coupler and venting out the gasses away.

Opposite end from the bullet trap is a small hole where you run parcord through the wall to pull the trigger of the firearm you are testing.

The Coffin is a bit pricey though at $20,000 and takes 12.5 weeks to build. But if you are in the business of testing firearms and need something to protect your employees this may be money well spent.
