The dimpled face on the Phase 5 PMR gives a more positive press surface than a smooth button. Gray anodize is unique, not many parts in this color. Drop-in fitment with the standard catch spring. Doesnt accidentally drop mags during recoil but light enough to press easily.
dimpled face on the mag release button is the differentiator, your thumb grips even with wet hands. gray anodize is closer to titanium than dark gray. phase 5 quality across the line
phase 5 dimpled mag release button in gray anodize. dimples give the thumb actual purchase, more positive than a smooth button. install is the standard mag catch swap. gray pairs with the PMR mag catch on the other side
The PMR mag release is more textured than the standard which helps with cold or wet hands. The dimpled face is exactly what I wanted for grip. Gray anodizing matches my Phase 5 lower well. Only gripe is at this price I expected a spring or pin in the box.
