After removing the magazine in double feed remedial action, what should be inserted next?

In the context of double feed remedial action, after successfully removing the magazine, the next step is to insert a new loaded magazine. This step is crucial to ensure that the firearm is ready to fire again once the issues causing the double feed have been resolved. A new loaded magazine ensures that the weapon is properly supplied with ammunition.

Using the same magazine after clearing or inserting an empty magazine does not address the need for the firearm to be combat-ready. If the original magazine was part of the problem (in the case of a double feed), simply replacing it with the same magazine could potentially lead to repeated malfunctions. Meanwhile, inserting an empty magazine would not help in preparing the weapon for further use, as there would be no ammunition available to fire.

Therefore, inserting a new loaded magazine is the best practice to ensure functionality and readiness immediately following the corrective measures taken during a double feed malfunction.
