    That is an easy proble to cheek just load a few rounds long and see if your groups shrink, that said you should be able to get good accuracy at mag length
    Punctuation is for the weak....

      Who chambered your barrel? It sounds like you may have the "Grendel II" chamber.

        Wouldn't a .135" jump be a longer chamber? I thought the grendel 2 chambers were a tick short?

          Tack driver - the Geetoo is the long throat big mouth version, whereas the group buy Satern barrels were short.
          If it's true that we are here to help others, then what exactly are the others here for?

            Send me a email with your order number. Let me check into the problem. Have you tried to contact us about this? You shouldnt have to work that hard to get sub 1 MOA. Is this a Heavy or light Contour? Either way they are guaranteed to shoot .5 moa.

                    The upper has been shipped to PF for accuracy testing. Mark made it very clear that they stand behind their guarantee. He is going mount the setup in a sled and shoot mag length ammo for testing. They should have received it last week and I will update this thread when it's wrapped up.

                      Certain mags now available will let you load to 3.0 length

                        Awesome, looking forward to the update.
                        Hey I'm not a complete idiot I have parts missing. Though some times I wonder.

                            ASC Grendel mags load to 2.300 easily. Some a tad more. They run in regular old AR15 lowers. I'm running about a dozen of them with Grendel cases and 6.8. Plus they are very inexpensive.
