Air Venturi Rail Lock Spring Compressor

  • Attaches to Dovetail/Weaver/Picatinny Rails
  • Allows user to disassemble spring and gas piston guns for maintenance/repair
  • Lightweight
  • Works with just about any spring piston powered rifle or pistol
  • Portable and compact - Just 9" long
  • Precision Machined


Air Venturi continues to innovate with products designed with the end user in mind with the world's first portable spring compressor—the Air Venturi Rail Lock Spring Compressor.

Weighing in at only 1.5 lbs this spring compressor allows airgun smiths and tinkerers to disassemble their spring, or gas piston rifles anywhere they choose. The spring compressor mounts on any piston gun's scope rail, whether Dovetail, Weaver or Picatinny, and allows for the safe disassembly (relief of pre-load) of the gun, with no workbench setup needed. Never before has replacing broken springs, burned out piston seals or leaking gas rams been this simple! The Rail Lock Compressor is just one more example of Air Venturi's commitment to designing tools that reward airgunners who know their guns.

Things I liked: The metal. It's solid. Not aluminum. Feels like stainless steel. This thing is built like a tank. Handles the spring pressure with no issues.

Things I would have changed: 1) Instead of using an allen wrench to turn the axis, they should have used one of those attachments you see on many vices--a steel rod with a ball on each end. It frustrates me to have that allen wrench keep falling out when I'm finished with a turn and the L port of the wrench is facing down. 2) Would like for them to include some kind of flat disc that could fit over then end (would look like a T, and just fits over the end piece). It should be made of the same material, and have two to three attachments: 1/2"; 3/4"; and 1". 3) Price. I think $90 is too steep considering the issues I've had with it (not workmanship issues, but how it functions). Include those those changes and I would say it is worth it. Otherwise, I'd say its worth between $60 and $70. However, and I will add, if you use this twice, and know what you are doing, it will pay for itself considering, for example, that here in Germany an air rifle refurbishment is about 200 euros.

What others should know: 1) I am using this on my Diana 75, with no worries. However, I have to bear in mind some of the limitations of this device. Which leads me to 2) when turning, it tends to turn torque off of a straight axis. So you will have to use your hand to guide it true and keep it centered, or you may get a handful of decompressing spring. 3) And this leads to the next problem--the threads can be a bit sharp. They will not cut you per se, but when you have to guide the rod true using your bare hand, you may experience some pain. I just use a rag, or you can use a glove. In my case, I have to guide it or it will eventually turn down and to the right, and eventually may slip off. Ouch! 4) You may need a metal washer, or a coin of some kind to place on the end. The end piece is about the size of a pencil eraser head, so it might be too small to safely retain the compressed spring.
