Weltool TC59 Click-On Lock-Out TailCap
This Weltool TC59 is a 1-inch diameter click-on lock-out tailcap that is compatible with Surefire 6P, 9P,6PX, C2, C3, Z2, L5, M2, M3, M3T and other flashlights. It can replace Z41, Z58, Z59 tail covers. The Weltool TC59 can withstand 4A current.
The TC59 tailcap are all made of machined aluminum and hard-anodized.
I received my tailcap quickly and it appears to be well made. It fit on several older Surefire and Solarforce P60 type lights without a problem. The momentary and click on functions worked fine. It seems to be a functional item.
