The fix involves using a Dremel tool to carefully relieve the V-shaped bevel on the rear of the PMAG that contacts the bolt hold open device. This modification ensures the PMAG functions like a standard magazine without causing damage.

Is modifying PMAGs safe for my SCAR 16S?

Yes, the modification is safe and recommended. It does not negatively affect the magazine's function or reliability. The primary goal is to prevent costly damage to the rifle's internal components.

How do I test if my PMAG needs modification for my SCAR 16S?

Perform a simple test: insert a loaded magazine into your SCAR 16S and check if the bolt hold device is lifted. If it is, the PMAG requires modification to prevent potential damage to your rifle.
