Great optic for ar's - Vortex OPMOD SPARC II Red Dot Sight

My dept has the expensive Aimpoint PRO's and they're awesome. I debated on getting one for my AR but I just couldn't justify paying that much for a red dot when I could just use my irons. Buddy of mine swears by Vortex optics and recommended the SPARC II, so I decided to give it a try. I only bought the OPMOD version because it was $30 cheaper than the regular SPARC II, even though from what I read they're the exact same optic. Easy to install, the 2 MOA dot is nice and clear, perfect co-witness setup as well. Luckily mine was almost dead on from the factory at 50 yards. Highly recommend this for anyone not wanting to spend big money on an optic.
