The roller cam pin can work with direct impingement, but the gas key needs to be swapped. If the mil-spec gas key is not replaced, disassembly of the bolt carrier group will not be possible.

For large frame bolt carriers there is enough space to swap the cam pin without needing a modified gas key.
