I just got my rifle back today from teflon coating, but the bolt won't engage. I was told I'd probably have to adjust the sear engagement, but the Timney manual said the sear was preadjusted at the factory and shouldn't be adjusted. I presume I need to take it to a gunsmith. It was set perfectly before the gun was sent in, and my gut feeling is that the bolt wasn't properly reassembled. It also may be a quick fix. I'd appreciate any comments.
