This valve key has been designed specifically for the removal and installation of the oversize release valve in WE M14 & G36 (G39) gas magazines, the larger diameter of this valve key provides a much better interface with the release valve which significantly reduces the risk of slipping which is the key cause of wear and damage.

Each valve key is fully machined from a solid bar of Grade 303 Stainless Steel with the back ground smooth for more comfortable use.
