So what we're looking at here is, if we put a CMMG .22 Ciener-type conversion set in a straight-pull Schmeisser SP-15 (with no gas, so not semi-auto), what is the difference in point of impact, of grouping capacity, and when we put it back to .223, will we have problems with extraction due to all the kak that the .22 set will deposit in the chamber and throat?

Let's find out!
