Newman notified me that my Panthera is being shipped back tomorrow. I saw that there is finally a video discussing the Bull Barrel. It’s By Europe Airguns and so it’s in Spanish with subtitles. It gives a lot of good information about the Bull Barrel. In all honesty, it is the video that FX should have produced. It discusses the plenum insert and the loss in plenum space. Apparently the Plenum adapter has a hex inside it to aid in removal and installation. I’ve seen estimates that the Bull Barrel reduces the plenum space by 20-25%. That estimate is incorrect. This video explains the math and how it reduces the plenum size by 50%. I’ll reserve judgement until I get my rifle back and see how it shoots. If you’ve heard or seen the reports about FX sponsored shooters shooting their Pantheras/Dynamics with Bull Barrels and no shrouds, it’s because FX gave them access to an enlarged plenum. The stock shroud doesn’t fit with the extended plenum. Even with subtitles, this video is worth watching.
I wonder if the extended plenum was always part of the conversion kit.
