Great optic


Had this for couple years, holds up to recoil. Clarity is nice, ACSS reticle is fantastic. Both eyes open very quick, just see the reticle on target. With the quick throw lever it's even better. Quit not owning this

I mounted it to my new AR10, out of the box right on the money. Crystal clear. Worked it out to 500 yards. Best scope I have purchased. Solid craftsmanship.

Great Scope and Incredibly Fast Shipping

I ordered this on New Years Eve. I figured between the long weekend and the current situation we are in, it would be a while before the scope was shipped. Primary Arms shipped this out THE SAME DAY. It was delivered on the following Monday (4 days later). Very impressed with that part alone. I haven't had a chance to shoot with the scope but I love the way the scope looks and feels. I also bought the Aero ultralight mount. I cant wait to test it out on the range.

All That and a Bag of Chips


Worth the hype.
<br>Pros: I particularly like the quality of this lpvo at 1x, it has a huge eyebox and wide field of view which makes it easier to use in a 1x manner than other lpvos I have used. The glass quality is decent for the price range, brightness of the glass is pretty good, the reticle and its hold overs are quite nice, the turrets feel nicer than many scopes intended to have the turrets used regularly,
<br>Cons: I do wish the scope had ranging by height like the SFP and not just ranging by width. I wish the brightness of the dot/reticle was greater so it could be used truly like a red dot during the day, but I can still see the reticle well enough that it doesn't matter much. The lens caps adjust the diopter, but that's life and common. I also really wish PA offered a calculator for the BDC where other ammunitions can be added. Burris offers this for the RT6 and it's awesome.

Great optic, great price

<br>Can't go wrong with this PA optic.

PA SLX 1-6x Scope

First of all, item arrived quickly. Had to wait for my QD mount from another vendor. After installing, I did a quick bore sight to get me on paper and did my fine tuning in the range at 100 yards. This scope is awesome! Good reticle and exceptional glass for the price. I have read from previous reviews that the illumination is somewhat lacking on very bright days. They were right. But it works for me just having it turned off. The black reticle contrasts nicely through a bright background. Hope this helps someone who’s still on the fence on getting one.

Excellent Optic


Anything just as good with a reputable manufacturer is gonna cost you upwards of $800 and beyond. This optic is exceptionally clear, stable, and robust. The only downside I have come across is that the highest brightness setting on a very sunny day is pretty dim compared to other LPVOs. Knowing this, I still rather save the extra $400 and go with the ACSS Raptor, and I believe that I made the right choice.

Good scope; great reticle.

Perfect length for a 556 bolt action rifle; the Millet SFP I had on it was way too large. Really nice and practical reticle. Allows you to range so as to use the appropriate hold-over for the ranged distance.

FFP and high quality for a great price


First Primary Arms scope I have purchased and I am impressed with this product. Bought based on multiple recommendations via the web. Solidly built, user controls operate smoothly and the overall fit and finish is great. ACSS illuminated reticle is quite different than other optics I have, but I really like it so far and understand why so many people recommend it.
