Are the Grendelhunter.com uppers the type that Alexander Arms sells with the .136 bolt that is SAAMI spec? Or are they a type II non-SAAMI?

they are the .136 bolt. No saami specs on the bolt. But the standard for AA and really any saami spec chamber will be .136 bolt. But the chamber is not saami. Its the grendel 2 chamber which does away with the compound throat. Some reports say that with factory ammo the Grendel 2 chambers don't get nearly as much velocity. On the other hand many say that with the grendel 2 chamber and loading out further allowing more speed in handloads.
