Failure to eject/ bolt stuck

[Klem]

Good morning Klem,

This is all new to me. When you say stuck in the chamber being normal do you mean to just tap it out or is the case really stuck normally? It just seems to me that anytime a case needs mortared out, something is wrong. Maybe to problem is greater with more straight walled cases like the Grendel???

Thank you

Not peculiar to just the Grendel - peculiar to the AR. I've used an Adams Arms piston in 223 with the gas set to OFF. The spent case is stuck in the chamber and requires a decent pull on the charge handle to get it moving. I've even see someone put the butt on the ground and use the heel of their boot on the charge handle but that's overkill and not something I would advise. Usually you can get it out by hand but needs more strength than usual.
