This bolt had a problem - Sharps Rifle Company Xtreme Performance Bolt

The bolt did not work for it was not correctly manufactured. The ejector arm was not properly machined and thus did not allow the bolt to fully seat and lock into the breach. The bolt appears to otherwise be of good manufacturing. The bolt has been returned for replacement for I believe the bolt will be very good if correctly manufactured. I am a bit concerned that I have not been able to communicate with the manufacturer about the ejector problem for I would be content if they sent me a new ejector arm. I am also concerned that the company's QA inspection did not catch the flaw. I would give the part a higher rating if it had worked.
