Will this lock up with other calibers besides 223/556? IE a 6.5 G or 224 Valkarie? — 1 Answer

It should work for any AR15 barrel with a standard AR15 barrel extension, so 6.5 Grendel and 224 Valkyrie should be compatible assuming the barrel has the star pattern in the barrel extension. Calibers like 9mm where the barrel extension does not have the star grooves would not be compatible.
