Parker Mountain Machine IDRS

Parker Mountain Machine’s new IDRS rear sight is now available as an option on their slide milling services for the RMR, RMRCC, SRO, and Deltapoint Pro optic cuts on the Sig P320, 365XL, and Glock 26/19/19x/17/34/43/43x/48. This cleverly integrated rear sight is secured via screws that come in from the existing holes on the sides of the optic and, as a bonus, it serves to hold the emitter window in place.

The IDRS option includes both the rear sight and a matching front sight for correct co-witness height. You can select this option when you select an optics cut from their Glock and Sig products pages at
