Trijicon MRO HD on co-witness riser mount and MRO HD 3x Magnifier on QD mount. Prefer to sell ONLY the magnifier for $500 if you want the optic you'll need to buy both starting at $2000 I don't have a lot of wiggle room so if you are buying only the magnifier I'm pretty firm on price, if you want both I'll have a bit more wiggle room on price. I'm open to trades of equal value.
