I bought this Primary Arms 1-8x24mm SFP Riflescope for my AR-15 in 6.5 Grendel. It is daylight bright with the illumination and almost a true 1 power but just slightly larger to notice its not exactly 1 power. It is still usable in 1 power with both eyes open though. After zeroing it for my 6.5 Hornady Black ammo, I was easily hiting 8" steel plates at 400 and 500 yards using the etched holdover lines. I also like the caps that come with the scope. They are definitely nicer than butler creek. The glass is also very clear and usable, especially for an optic in this price range.

What a great scope. 1-8 zoom is perfect. The ACSS reticle is top notch, the range estimators built in are innovative. 4 stars because it has 1/2 MOA adjustments and I think it could improve with 1/4 MOA adjustments. Also, wish the whole ACSS reticle would illuminate to include BDC and range estimators, not just the horseshoe and chevron.

After a couple trips to the range, this is my opinion. Construction seems very sturdy and mechanically sound. Glass is clear at all magnifications. Reticle is very useful and so far the BDC and ranging marks all seem very accurate. The only draw back for me, is the change in eye releif from 1x to 8x. While it is normal for most variable optics to have a change, this scope seems to be more pronounced. On my next trip I'll try to measure the difference, and edit this review. All in all a very good optic at a good price.

When it comes to firearms and accessories, I always abide by the age old saying that you get what you pay for. Its tough to bring quality optics to market at affordable prices and even tougher to go against big names such Trijicon, Vortex, Leupold, and even Nightforce. When Primary Arms brought out the 1-8 ACSS SFP scope, I was hesitant to jump on the train at am optic coming in <$400 in a market ruled by $650-1000 scopes. Surely this couldn't compete and sacrifices had to be made to come in at that price point. Well, I was wrong. Reading and watching countless reviews with nothing but good things to say with this Primary Arms optic, I decided to throw the dice and pick one up. Well, what do I have to say other than WOW…This optic has clear glass, and I mean clear glass. You will notice this right away. Now, its not Leupold Mark 4 or Nightforce clear, but you are going to have a hard time noticing differences with scopes such as the Vortex Razor HD which come in at almost 3 times the price. FOV is another big thing. This being a 24mm eyebox, it gives you a FOV right up there with something like the Razor which is 26mm and I would say its right there with the Vortex Viper line, the Leupold VXR line, and dare to say right there with the Trijicon Accupoint. Eye relief is very forgiving, and you will only notice your eye relief starts to narrow past the 6x mark. The ACCS reticle is phenomenal and gives you everything you need for quick ranging without cluttering up your FOV. This was my biggest complaint with scopes such as the Viper PST which to me had an unusable BDC reticle. The illumination is daylight usable but nowhere near something like a Leupold VXR with the Firedot or a dual illuminated Trijicon Accupower/Accupoint. It's good though and you have the etched reticle which is easily usable. The cons: Well, you don't have the exposed turrets like say the Viper PST. Now, it would be tacticool to have them but if you are using this as a fighting rifle or 3-gun rifle, you aren't going to be making windage or elevation adjustments on the fly anyways. And, the only other thing they could do better is to put off settings between each illumination setting so that you can power the scope off and click right back to your last setting. Other than that, very solid scope. Throw this in an American Defense mount and go. I'm running this on a SCAR16 currently and its doing great and we all know that SCARs are hard on optics. Great scope for the cash.

After lots of research it’s either the Vortex or PA 1-8. I think either will do the job as they are so identical. Probably made in the same factory. I chose PA because of the ACSS rectical and it’s intuitive to me. Magnification at 8X is a little tricky as you really need to find the right position for your cheek and eye but it’s doable with more practice.

This scope is a great "bang" for your buck!!! Extremely well built, great clarity in glass, tactile and audible clicks on the turrets, smooth but firm rings for the focus and zoom, illuminated reticle is a great plus. The ACSS reticle is absolutely amazing and simple to use. I've used it from 20 feet and out to 425 yards so far and the clarity and accuracy is on point and better then what I expected for such a low cost optic. I highly recommend this for those looking for close to mid range shooters as well as those long range shots.
