My dad has one. They are pretty light but per my phone calls with SilencerCo they are a “hunting” suppressors and not intended for rapid fire or high volume.
They do have minimum barrel length / recommendation and I think the guy I spoke with said it can handle something like 6-7 shots per minute on 300 Win Mag which for his hunting purposes was fine.
I’d bet yours would be fine with enough barrel length. Did you try to call them?
