Starting to research a case to house both of our R8's.
Mine came with the Blaser foam inside a Pelican 1700, but only fits one rifle with 2 barrels.
I went on My Case Builder and made one for two rifles and two barrels.
I have to leave the bolts in the stock to make it fit, but it does fit.
I may try a Pelican 1720 case and see if I can get three barrels to fit.
