Vortex Defender XL (DPP Footprint) 5 MOA Red Dot (w/ MOS Plate, Low Pic Mount)
Vortex Defender XL 5 MOA red dot sight with the DeltaPoint Pro footprint. Has been used and was mounted on top of a rifle scope as well as on a Glock with the included MOS plate. It also has a low picatinny mount as well. Tiny bit of marring on the finish of the front "strike" surface which is textured for racking the slide off of a barricade or what have you (I tried it out, hence the marring).
The window on this optic is very clear and big. I really like it in all honesty. Just moving to a different optic cut. Uses CR2032 batteries and has all of the usual features including auto shut-off and night vision settings. MSRP new is $399.99
