There is a conversion for the 97 - but right now I do not think you can find one. There is a possibliity that White Rifles may have the conversion available later in the year... see this thread....

Here is a pic of the parts... it is a great conversion and really works well - still probably not what you want to shot BH-209 in a White - I would stick with T7
The breech plug on the left is Doc's first attempt the one on the right is the sewcond generation and works far better...
