I have come to the conclusion that the Ammo is just bad, the ammo must have been old stock.Combined with a Polygonal barrel already running at a higher rate of pressure it has to be the ammo.I have torn this rifle down to bits and pieces this last week and can find nothing that looks as though it is malfunctioning. I have added some more photos but until my A-max ammo arrives I can not test it out.The only change I made is to add an H buffer and await the ammo.http://www.65grendel.com/forum/album.php?albumid=67
