I bought my dad a 6.5 Grendel upper to deer hunt with since his bad shoulder prevents him from accurately shooting a standard rifle. He is having issues with feeding on the initial charging of the rifle. The bolt never wants to go into battery after picking up the first round. Usually have to drop the mag and pull the bolt back again and let it seat itself over the round in the chamber. Upper was purchased complete and using 6.5 Grendel specific mags. Anyone have any idea what could be causing this?
