As above, the only off the shelf actions are CZ 527 and the addition of the Interarms Mini Mk X /Remington 799/ Zastava 85. All are different names for the same action. Available in 7.62x39 and cheap enough. Someday, maybe someone will do a Grendel on a old Sako Vixen action but I doubt it. The Howa mini action is conjecture and I'm ready to buy a Grendel from them if any are made. And yes, I push more pressure through those actions than an AR, kinda creeping up on a 6.5x55.
