IMO, Primary Arms makes some of the best bang for your buck optics out there. I have a few red dots from them, plus their 1-6x scope, and they have all been reliable, held zero, and performed much better that you would expect for the price point.

While I now know more, I'm no closer to an answer for what to purchase. I've been looking at a few RDS and scopes, pretty much decided the stuff under $100 won't last or even work decently. But I don't have the means to make multiple purchase of hundreds of dollars each to determine what works. So many pros and cons to consider.

Thanks for everyone's input on this subject.

It really depends on what type of shooting you will be participating in. Run and gun where time is key and a hit on a steel gong is a hit calls for red dot.

Shooting from the bench trying to make one ragged hole at 100 yards is scope.

Primary reason for wanting an optic is home defense, close quarter battle. To be able to get quick on moving target.

That's a red dot all the way then. For the money, I highly recommend the Primary Arms Micro Dot. 2 MOA dot, size of an Aimpoint T1, NV compatible, and a 50k hour battery life. with a mount it is right at $200, and it is a lot of optic for the money. If you wait a few weeks, you can probably get your hands on their new micro dot that is being put out in conjunction with Holosun. Same micro dot, same battery life, but with their ACSS reticle, which has a CQB horseshoe, aiming chevron, BDC, and ranging ability. $220 with the mount. I'll be picking one up as soon as it is available.

Red dot for hogs, CQB, short to intermediate combat distances (up to 200 meters), other fast moving targets. Scope for precision, hunting, and targets past 300 meters.

I like the 1-6x variable scopes. They are almost as fast as a red dot and give you the advantages of the magnification at longer distances. I have the Primary Arms 1-6x ACSS scope on my 18" AR, and it is awesome. It is literally the exact same scope as the Vortex Strike Eagle (made on same line in same factory) but with a better reticle. The two downsides to the variable scopes that keep them from being my absolute first choice are weight and battery life. Variable scopes are heavy, especially when compared to a micro red dot. Battery life on the illuminated reticle on a scope is measured in hundreds of hours. My PA Advanced Micro Dot has a 50k our battery life, which means I can leave it on in my closet, ready to go for home defense, and change the battery every year on my birthday. Those 2 things give the red dot a huge advantage when movement and speed are a concern.


When it comes to red dot vs. reflex, I prefer the red dot, simply for battery life. The micro red dots especially are awesome, and they don't give you the "looking through a tube" feeling that older, larger red dots do.
