Well, I just picked up an AR in 300 Blackout from one of the guys I work with. It's a flat top, keymod build, so I gotta put an optic and some MBUS on it. After watching a ton of video reviews, the Sig Sauer Romeo 5 is looking like a winner. I'm sure several of you guys own this little red dot. What's the good, bad and ugly about it? Is it worth the scratch? (140 bucks shipped on Amazon) Or is there another out there that's just as good (or better) for less cash? Remember...I'm a poor ol' broke cop without a lot of moolah, so please don't recommend Aimpoint or EOTech or the like. I just can not afford them.
