A lot of scope for so little money

by -

Wow! A first focal plane scope for less than $300 with glass quality of a $800-1000 FFP scope. Reticle is clean and easy to use. I was all set to purchase an Athlon scope for 2.5-3 times what this one cast and I'm glad I purchased this scope and spent the savings on ammo. Glass quality is great. Mounted on a 224 Valkyrie build and have only had the gun and scope out to 200 yards and plan on taking it much further and also doing some tracking tests during a PR class in a few weeks. It was on paper at 100 yards right out the box and zeroed quickly. The only "wish it had's" are a true locking zero stop and the reticle illumination and parallax adjustment controls on the same knob. The only ding I can give it is the markings on the adjustment knobs do not perfectly line up with the reference markings on the turrets; they are about half a click off. Overall, for the low cost, this a damn nice scope that looks to be extremely capable of hitting targets out to 1,000+ yards.

Primary Arms does it again!!!!!

Incredible! I love this scope. It is everything I want and need in a FFP optic with a $300 price tag. I wish it would've come with zero stops but with a google search I found a solution and the work great! Go to Non Ferrous Fasteners Inc and search NF9320, you will have your zero stops in about 3 days. I have ordered another one of these for my new AR10 build. I recommend these to anybody I speak with looking for a higher power optic. Now, PA needs to make a ftp 1-6 with this reticle in a lower budget optic.

Completely impressed

by -

First off, shipping was outstanding!!!! I placed my order Wed and scope arrived Sat. I was expecting at least a week on the free option. Thanks for taking care of your customers PA!!!
<br>Pre shoot thoughts - looks great, glass is clear, reticle is sharp. Tracking seems good without doing a box test. Viced the gun at good target, 15 clicks up, 30 clicks down, 15 back up and was back on original target. Well worth the $$
<br>Will update in a couple weeks after 100 rounds of 300 win mag.

New,Happy,Repeat Customer

by -

Gave five stars as of now. AFTER ordering,(because I always do things out of order), I emailed PA to ask if this scope would handle recoil from 300 WinMag, they said it wasn't rated for magnum rounds but many customers had good results with that combination. We will see, since that is it's intended purpose.
<br>Glass is clear once you find the "eye box". Illumination is good reticle is great. Seems like well made scope. Turret reset option.
<br>Once I properly adjusted focus(diopter) zoomed in down the road and parrallax worked great. I have to say the glass is not as good as my Nikon scopes, but the price is right.
<br>So far very pleased. Haven't tried to track the reticle such as box test. Will update if any problems.
<br>Overall great deal. Shipping was fast. Ordered Tuesday, received Friday.

Great Scope, AMAZING Customer Service


For the money, the scope is amazing. Glass is clear, turrets track and return true, the reticle is sharp and clean, and FFP in a scope at in this price range is unheard of.
<br>I did have a small manufacturing issue on mine which was more of a picky detail. The scope arrived Wednesday evening, and I had a match that I was hoping to use this for on Saturday. Later that night, I sent an email to customer service explaining the issue. Before 8:30 the next morning, I received an email back saying that an RMA and shipping label were on their way, and that a replacement was being overnighted so that I would have it for my match. It arrived Friday afternoon, and worked perfectly in the match. Thank you!

Excellent Customer Service

by -

Started with a lower grade PA scope, it was accurate but did not hold up. The folks at PA stood behind their product and made things right. <br>Decided to go with the ARC-2; mounted it on 20MOA rail, looks good, glass is very clear. Tested and confirmed reticle graduations to be accurate.<br>After dialing in shot two three shot groups below half inch deviation. Will know after a few weeks if it is going to hold up. <br>Must admit I do business with PA because of their excellent customer service.

One of the best optics for the money

by -

I sold firearms and optics for a big box firearms retailer for about three years. Of the optics that I sold there my default best for your money was the Vortex Diamondback or better line of scopes. This scope IMO rivals the Vortex Viper HST and the new Diamondback FFP 4X16 with the EBR2 reticle for clarity and features. Dollar for Dollar I'll take the PA FFP 4X14X44 scope all day every day over the Vortex scopes.

Every good scope just turret lines don’t line up with scope


I love this scope. Very clear and smooth. I’ve had it out to 300yd tracking with the turrets and it repeats every shot going from 100, 200 and 300 yards. The only reason for the four star is because of the turret lines don’t line up with the line on the the scope. The turret lines sits off to the right of the line on the scope. Scope still works fine just bugs my ocd a little bit.

Excellent scope for the money!

by -

As Jason mentioned: the turret lines don't exactly match up on the turret caps when you go to zero...also off slightly to one side or the other. For the price of the scope though I really can't complain as other than that; this is a great optic! Very clear and feature rich + first focal plane for under $300?! Honestly this scope is a steal for this price! Have this mounted to my 6.5 Grendel and pulling off Sub-MOA groupings with it!

Great optic for a great price.

by -

This optic is worth every penny. I was able to get it zeroed quickly, the illumination range is incredible and with my precision bolt gun, have gotten consistent sub MOA groups. When I first went to zero it, the RO was practically drooling over it, and could not believe the price when I told him. I am planning on ordering a second one when I get ready to build an AR10, as I can't imagine a better optic to use. If you plan on shooting anywhere from 100 yards to 1,000 then this is the optic for you. I also got a sun shade with it, and it fit perfectly and worked exactly as advertised.

Didn’t quite fill the bill.

by -

Bought this based on some good reviews. And that I was looking to up my magnification. Expected more. Brightness is a lot less than I expected, especially at max magnification, which negates my original purpose. And, loads that shot sub MOA with my previous scope are about 2 MOA with this one. I’ll be removing it and going back to my previous scope. Brighter, clearer and holds zero, just not as much magnification.
<br>From PA: It sounds like you received a bad one. We'd be happy to swap it out for you. Our customer service team has tried reaching out to you but they haven't been able to contact you. Please give us a call at 713-344-9600.

Looks good ootb, but eye relief is a concern

by -

So far so good. Have not shot it yet, but playing with it at home, all of the knobs turn smoothly with positive detents/clicks. At 14 power the eye-box isn't very forgiving but not a problem if your on a rest or bipod. My biggest concern is eye relief. With the placement of he illumination knob there isn't much room to adj the scope placement in your rings. I suggest buying rings with less than 3 screws unlike I did. Luckily for me the eye relief is ok on my rifle but it may not be for you.

Great scope!!

by -

Bought this for a .224 valk AR build and definitely doesn't feel or perform like a sub $300 scope. Its feature rich, and does everything just as good some of my more expensive scopes. It does have some minor draw backs ie the elevation turret doesn't match up exactly but it's nothing that takes away from its performance. I was able to get 1/2" groupings at 100 very easily as well as sub MOA at 200. If you're looking for a reliable damn good scope that's good out to 1000 but don't want to dip into the kids college funds then this is it! I'd easily pay $500 for this and have zero regrets. Good stuff PA, keep it up!

Great FFP scope with great reticle and decent turrets.

by -

The glass is great for the price, it has never held me back. The tracking is acceptable for my skill level 1330 meter personal record) and is usually very close to my Hornady software solution. The holdovers in the reticle are also very accurate. My only complaint is when trying to shoot small groups at any distance over 100 yards. The reticle at 14x will block out a small bullseye at 300 yards. Would be great if they could throw a chevron or finer lines and s small gap near the center. Holds zero without babying my rifle all the time. Batteries for illumination last quite a while if you only use them when necessary. I did give it 4 stars but I have purchased 2 of them FWIW. Adjustment fore and aft in the rings is very limited because of the illumination knob.

Great scope


I have several scopes on my rifles, all are good name brand scopes. I was looking for something to go on my 6m Remington, after trying primary arms I was very satisfied. Will definitely buy another.

Super Satisfied


Really happy with my scope! I have it mounted on a Springfield M1A Loaded and it looks great. Glass is bright, tracking seems fairly accurate.
