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: Gets the job done

Things I would have changed: Allow nylon end fitting to rotate and be easily replaceable

What others should know: I used a 2" hose clamp to prevent the press from walking off end of the gun.

Things I liked: This compressor works great. I use it on my Diana 34 with no issues. It locks tight on the scope rail and adjusts very easy. It's also very compact and can be used on a desk or table top.

Things I would have changed: Nothing.

What others should know: At first it was a bit awkward trying to get it all lined up. After a couple of uses I was using it with no hiccups. I did have to use a very small thin piece of wood the size of a matchbox car between the end of the drive screw and the spring block. No big deal though.

Things I liked: The dovetail attachment doesn't slip while compressing/decompressing the gun's spring. I was worried that it wouldn't hold. The compact size is very nice.

Things I would have changed: The fast release button doesn't work on mine. Air Venturi ought to just skip that and simplify the design. They'd be able to offer it at a lower price that way. The spring compressor was also a bit rusty straight out of the box. They aren't deal breakers but... I think they could have dipped the thing in packing grease and put it in a plastic bag before it left the factory. Hence my four star rating.

What others should know: I used my spring compressor to replace the spring in my Hatsan Dominator. I needed a wooden block to do the procedure. Otherwise, it was a no go. I drilled a 3/8 inch hole in the wooden block to fit over the nylon end of the screw. Then, I cut a slot on the other side of the block to fit the tapered end of the end plug on the rifle. With that wooden block, the procedure went smoothly. I didn't have to "guide" the compressor's screw at all. It stayed in place but only with that wooden block.
