I am offering a very rare YHM Mini M4 7.5" Upper 1 in 9" twist for use in California Legal Handguns for $350. It is a PTAC upper receiver, PTAC 1 in 9" twist barrel, mini 4" quad rails, forward aid and gas tube setup included. All that is required is a total BCG and charging handle. I do also sell the full bolt for $100 and $30 for the charging deal with if required. All that would be needed is a completed lower. Thank you for looking.

　　to meet in Sacramento or Folsom.
