Thread: Bolt won't fully close - used to

I took my stock off to send the barrel away with receiver, timney trigger and rail still attached. Put it back together to try it out today but the bolt would only close halfway, with or without something in the chamber. Trigger still works in that position but I don't want to test a live round with the bolt half cocked. Any ideas on what the problem is? Gun's practically new, Rem Sendero.
