UPC 605930624717.\u003c\/p\u003e\u003cp\u003eThe GM is the flagship of the 515 series: the same duty-ready package as the HS515CM, with the 7075 aluminium housing replaced by titanium. That gets the complete optic down to 3.74 oz (106 g) while raising, not lowering, the strength of the body — which is the trade weight-conscious rifle builders are usually looking for. Rotating protective lens caps with a kill flash guard the glass, Solar Failsafe backs up the side-tray CR2032 for up to 50,000 hours with Shake Awake, and the unit is rated IP68 and IPX8.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe aluminium version is the \u003ca href=\"\/products\/holosun-hs515cm-red-dot-sight-multi-reticle-system-solar-qd-hs515cm\"\u003eHS515CM red dot sight\u003c\/a\u003e, with matching optics, QD mount and lens caps at lower cost.
