For my two cents, this is a really good low price (CQB) optic. Look, it is for an AR-15 Rifle in Close Quarter Combat situations. Too many times folks are looking for a perfect sub $300 optic that does it all. Frankly, there is no weapon system that truly does it all. Same goes for the optic.
The description from Burris calls this a CQB optic in the description, sub-100 yards! I have one on the upper of my Windham AR-15 .223. It is a good optic for sub-100 and reliable also using the etched prism or when lighted. I don't have it on my .300 Blackout upper, I have a Leupold 3-9x44 on it.
If you want to spend upwards of $2200, then get a used Leupold Mark VI with an integral mount. I have one, but it is on my 1000 yard, 6.5 Creedmoor; Bergara B-14. I have spent a lifetime in Marine Corps and Law Enforcement. There is no one size fits all when it comes to weaponry. Truthfully, if you can shoot at all, flip up optics on an AR are the way to go for defense and fast target acquisition in a defensive posture, which is what CQB is.
I want to meet the guy who can get off five .223 rounds in a 20 inch barreled AR in 15 seconds, sub 2 moa, at 100 yards, regardless of the optic. Most can't do it with a bolt rifle.
The thing that Burris did was actually tactically sound given the Peter Principle. Battery dies at the worst possible moment, etched reticle, problem solved.
