Pro-Arms RMR Scope Mount Base for Elite Force / Umarex GLOCK 17/19 Pistols

"Solid build and construction. Good packaging too. Not sure about fitment of EF or TM Glocks, but for anyone wondering if this would fit on an WE G18c, it does not.

Will be returning because of my circumstance, but the product itself is fine.

"Works with the new Elite Force Glock 19x. Unscrew the OEM philip screw, remove the rear sight (takes a bit of effort to remove the rear sights and the iron sights on the 19x are plastic), slide in the RMR base-plate, and use the longer hex screw to secure the base-plate. However, this base plate will only work with Trijicon style RMRs.

"Update: It will work for EF glocks! undo the blow back screw and you can slide the dove tail sight all the way off. Pull the metal insert out, and this mount will fit right in. You can also mod TM style sights to work with EF as well!!
