AR-Stoner 6.5 Grendel barrel short chambered.

+1 so until now we still dont have any clear answer.
no second hand info from satern.
No answer for reamer use in Liberty Barrel & the hand lanp barrel (spartan barrel?).
since for some of us we just want to shoot it using factory ammo with out any modification

I'm pretty sure everyone can shoot factory ammo from hornady and wolf without issues. As we saw one example needed the chamber polished when shooting aa ammo.
