Tired of hearing that ringing sound every time you shoot your AEA air Rifle   🙁

+  Best design for eliminating ALL of the ping sound.

+  Small size takes up less air space inside the air reservoir.

+  CNC machined from a solid piece of durable 6061-T6 aluminum, then anodized.

+  Built to last forever.

+  No loss in power.

+  Won’t deform or break into pieces like plastic depingers do.


Easy to install:

Make sure your AEA airgun is not loaded. Degas your airgun. Remove the air reservoir tube. Install the hill airgun AEA depinger into the air reservoir tube just past the threads (see the above picture). Do not push the depinger far into the tube. *The o-ring end of the hill airgun depinger goes toward the gauge end of your airgun. Reassemble your airgun. Cock your airgun before filling with air.
