Looking for something for my old HyScore 820. Will the Beeman universal work? Their site says not for HyScore recoiless, although is seems to say for all Diana's.

I doubt it. My 75 isn't here at the moment but it seems that even with everything off, the barrel diameter would still be larger than the "Beeman" brakes which fit the HW rifles.

It'll be a few days before I could give you a definitive answer. Sorry 'bout that.

Then again the HW's I have are all a bit older. The newest being the R11 and that's a whole different matter.
