WILL NOT WORK CORRECTLY ON THE NEW ZENITH CLONE WITHOUT FILING THE FORWARD EARS ON THE SIGHT WELDMENT. IF YOU ARE NOT COMFORTABLE FILING ON YOUR FIREARM, PLEASE DO NOT ORDER. It has come to my attention that the screws shipped with the RMR and SRO are longer than normal, this is causing them to bottom out on the receiver and create an issue with the optic producing a gap at the front of the mount. Please use the mounting screws included with the mount. Will not fit the new PTR with welded pic rail without milling removal of the three rearmost lugs. Does not fit the Holosun 507K.

NO REAR SIGHT …… ADD YOUR OWN GLOCK REAR SIGHT

This specially designed rail attaches to the rear sight boss on the HK MP5 as well as most clones and variants. It is NOT designed to fit airsoft or GSG rimfire models. CNC machined from 7075 aluminum bar stock and hardcoat anodized with only a machine finish to show the exemplary quality of manufacture. I designed it for the Aimpoint micro line of optics but any small format sight will work fine. I added a provision in the rear to add a back up sight in case the optic fails. It utilizes a standard Glock rear sight dovetail and can be upgraded with the sight of your choice. Includes grade 8 mounting screw, US 3mm hex wrench, Loctite 242. and detailed instructions.
