    • Excellent optic
Style: 2 MOA Red Dot
Excellent optic at the right price. Shake awake is the way to go. Will purchase another. Dot is bright and battery lasts a good long while.

    • What can I say.
Style: 2 MOA Red Dot
What can I say I’ve had PA optics since their start and they continue to innovate and impress. Dot quality with my astigmatism is fantastic even under a magnifier. It’s NTOA approved and on my duty rifle. Minimal parallax and has taken a good beating and held zero. Can’t go wrong with PA.

    • Great product for the price
Style: 2 MOA Red Dot
After using this for quite some time now I can honestly say that you cannot beat this product for the price. Easy to dial in and is robust, no issues with it coming off of zero. I ran this on both my 12 gauge and 9mm carbine.

    • Solid optics
Style: ACSS Reticle
Solid optics. Big fan of the reticle and controls.

    • Great optic
Style: ACSS Reticle
Crisp and bright. Chevron and drop markings are fantastic when paired with a flip up 3x or 5x magnifier. Great for the price!

    • Primary Arms optics
Style: ACSS Reticle
This is a super sweet little red dot. Comes with 3 separate bases so it has multiple mounting options. I just attached to pic rail. Arrived 4 days early and that was nice. I love Primary Arms optics.

    • Well built but I got a defective one. Would consider trying another unit when it comes out in green.
Style: 2 MOA Red Dot
The price is right and this comes with several mounting options and heights. Unfortunately, I got a defective unit that had to much bloom and artifacts on the last 4 brightness settings. I have a prism scope from Primary Arms and so far it has been good to me. When you compare their optics to Sig Romeo, Holosun, and Vortex, Primary Arms has better prices and lots of mounting options. I usually prefer green prism scopes or green circles with dots in the middle. Even though I got a bad unit, I would definitely try again when they release a green dot version of this optic or when they make a red Gen 3 with multiple reticle options like Holosun offers. ... show more

    • Best bang for your buck!
Style: ACSS Reticle
I'm truly impressed by this sight! Crisp glass, rugged, perfect for left handed shooter like myself because the rotary know is on the left side, and very cost effective. Also if you want a great magnifier that doesn't cost $200 or more then go check out monstrum ghost prism magnifier. It pairs perfectly with this red dot! ... show more
