The TRYBE Defense AR-15 Fully Assembled Upper Receiver Type II w/ Dust Cover & Forward Assist may be able to replace the polymer upper on the Chiappa M4-22. However, I recommend contacting the manufacturer to confirm the compatibility of the upper receiver components with a Mil-Spec upper. If there are proprietary components that require the use of that polymer upper then it will not work.
