extra plenum made by Raw

I have one that was made long before RAW offered them for sale but it's almost exactly the same. It was made by a friend of a friend that works at Utah Airguns. There are a quite a few posts about it here on AGN. Yes, they do work and will increase velocity. If I remember correctly, I gained 35-40fps when using the .25, Varmint Knocker 32.8gr or Zan 33gr slugs without having to crank the hammer spring or regulator. I made other internal modifications too, so your results will differ, but I went from about 945fps to 980-985fps. It's a great accessory for a terrific airgun. You'll love it!
Have a great weekend!

I attached a photo. Even with a 700cc bottle, it Doesn't look out of place.
