I have a Charles Daly 12ga 3" semi auto that apears to have a piece of free floating metal in the bolt group that is causing it to lock shut

. Occasionaly i can see it from the hole that the charging handle is in. Does anyone have any advice. Charles daly is out of business correct?

Can i still get it factory repaired anywhere?

Any advice or input will be helpful as am am nowere near being a gunsmith. Oh yea Is this a common problem?
