6.5 in an other platform

[VASCAR2]

You may be right, I agree the 300 Blackout is a very simple conversion since the bolt is the same as 223/5.56. I assumed a new bolt and barrel extension/barrel would have to be designed and mated to the long stroke operating system of the Tavor.
From a business perspective I have no idea if a 6.5 Grendel Tavor conversion is financially feasible. Strange I always want things that are not available but I would buy a 6.5 Grendel Tavor before buying a 9 MM Tavor.
