Warpaper posted their take on the Guns Modify Glock 17 RMR Slide 2015 Version which is an improvement of their 2014 version. Made primarily for the Tokyo Marui Glock 17 Gas Blowback Pistol (and compatible GBB pistols) they find the replica very detailed with luminous sight, neat markings and engravinbgs and can be installed easily.
