Hey nation, got an odd problem here with my TM7 and was hoping someone knows what to do.

I own a TechT MRT bolt for TM markers and the inner bore of the bolt seems to be too small for the bolt guide, and as I try to fire, the bolt will be stuck halfway in the breach usually until the third shot (on burst or auto, and semi if I pull the trigger quickly enough). Has anyone else had this problem? I switched back to the stock bolt (with some difficulty getting the techt one off) and the problem was gone. I'm unsure if my bolt is just defective or if this is normal until it can be broken in. I emailed techt after I noticed this but 3 weeks later they still haven't responded.
