Butler Creek flip-caps

by -

The Butler Creek Eye: 17 flip-cap is too small. The Butler Creek Objective: 02A flip-cap fits just fine. The scope is great! Really enjoying it.

Amazing Reticle

by -

Loving this Raptor Reticle . Very quick to acquire targets in 1x .

Pretty nice, great reticle

by -

First things first, this is a relatively lightweight First Focal Plane optic that retails for around $400. That such an optic exists (let alone with my favorite reticle so far) is great in and of itself.
<br>But there are some inklings of the cheaper price. First off, 1x isn't a true 1x, which is pretty normal in a variable zoom optic. It's around 1.3 or 1.4x though on this optic if I had to guess. Second, there's a good bit of blur or distortion around the edges of the sight picture on 1x. Finally, the eye relief and eye box are pretty unforgiving at 6x, even for a 1-6x.
<br>On the good side, adjustments are good and solid. There's very little discoloration or tint through the optic. The lighting is also plenty bright, in my opinion.
<br>For the price I'm pretty happy with it. It's lighter than expected and plenty workable.

The gamble paid off!


I wasn't sure if trying FFP was going to work out, but I took a gamble on this despite a lack of many reviews. I finally got it sighted in and shot my first 3-gun match with it today. It was my best outing with rifle ever! I mostly attribute this to the chevron reticle, which is a big improvement over my Strike Eagle 1-6x, though not exclusive to the FFP model. I think they implemented better in this model, though. The picture was bright and clear, the lighted reticle was very bright in daylight, the variable size reticle from being FFP was neat, the built-in throw ring was easy to use on the fly. This was a local club match without long distances, but even at 125yds I could get on target much faster and better than before, and actually hit them as an added bonus! I see this is going to work at my other match with longer distances.

Budget doesn’t have to mean low quality!

by -

Great optic for the money,glad I waited/saved for the FFP model and the ACSS is the best retical imho. I was pleasantly surprised by the glass quality. It’s a little unforgiving at 6x but for me it’s not a problem because I usually slow up when @ full magnification anyways. All in all solid product for Primary Arms and love they’re lighting fast shipping.

Great scope!!!!!

by -

Done a lot of research before picking this scope. must say the videos done by Dimitri where very helpful. Mounted my scope up in a pepr mount and took it to the range. Fired 5 shots and it was 8" low but right in line with my target dot. Moved the reticle up the right amount of clicks. Shot 5 more and it was right on the target. So far I'm very happy with this scope. Should work for all predators 4 legged and 2 legged. The acss reticle is very easy and quick to judge range. Great scope would highly recommend this scope.

No Better Bang For the Buck!!!

As a 3 Gun competitor I am always looking for new equipment to get the edge. I've been wanting a 1-6x to replace my very venerable 1-4x that I had been running for years. The trick was I wanted one that was first focal. This is the 3rd scope that I have gotten from PA and this is the best one yet. I have it mounted in a Midwest Industries mount and it is rock solid and dead on. Finally got a chance to use in a match and what a difference it makes having the reticle that goes down to nearly red dot size for speed on close stages and the 6x is clear and sharp. Just went out to the range and tested the magnification and zoom staying true and it was ringing steel at 300 yards at 2.5x using correct hold. So impressed will be getting the .300blk for my blackout very soon (also may pick up another 5.56 one too).

Wind holds and BDC accurate and perfect for run&gun


Had never shot with this scope more than 100 yards a few times to zero. Used it for a run & gun this weekend. In moderate wind, hit 4-500 yard targets on first shot. The wind holds and BDC are incredibly accurate and easy to use. Especially for the money, I cannot recommend this enough.

High Quality, especially considering the price. Awesome Value.


First impressions are really good. In hand it feels more like $500+ optic. Glass is super clear. Time will tell how it holds a zero, but I don't anticipate any problems.
<br>I did ask for a photo of Patrick Swayze, and they didn't include it. Which made me sad, but I'm really happy with the optic.

Best in this price range.


For this price and the features you receive, this product cannot be beat.<br><br>After shooting red dots,ACOGs and other optics, I wanted to test the LPVO waters and I am very impressed. The glass is good, adjustments are solid and clicky, not mushy. Magnification is smooth and fast.<br><br>The reticle...the ACSS reticle is bananas. I consider myself a master of hold over with a red dot...but never in my life have I sighted a optic in and immediately began making hits on 6” steel at 300+. All credit to the ACSS.<br><br>Which brings me to the best benefit and/or perk of buying this product...if you contact PA, they will assist you with setting up your optic using various loads. The creator of the ACSS reticle, Dmitri is clearly approaching level 100 wizardry<br><br>The illumination is bright, plenty bright even for use in the day. Unless youre aiming at the sun(enjoy being blind) or other immensely bright background. Which actually what brought me here. <br><br>Dont hesitate!!

Good balance on fast target acquisition and far target engagement

by -

I purchased this scope back in December, and have taken it to the range mounted on a 18in 223 wylde AR15 a dozen times. The glass is very impressive at this price point; I think the light transmission is above 90%, and there is no edge blurring. The reticle lines and center dot are large enough to enable fast target acquisition while still shooting sub-MOA groups. With hand loads, my gun with this scope is shooting 3/4 inch or better groups at 100 yards and 2 inch groups at 300 yards.

Great scope for Money!!!!

by -

I bought this scope to place on my Colt HBAR. I put it in my Larue LT104 and headed to the range. Started at 25 to get on paper. I put the scope at 1 power for the 25. I was on paper and centered but high at 25. I dialed it down 2 1/2 inches and headed to the 100. I put her on 6 power and dialed it in for a final zero.
<br>I shot 20 rounds of Federal 77 grain HPBT at 100 yards. It shot a one inch group which is pretty good with the stock trigger in the HBAR.
<br>I love the ACSS Reticle and the accuracy of the optic.
<br>The only downfall is the brightness is not daylight bright even at the highest setting. But for a sub $400 scope that can be expected.
<br>** If it was daylight bright it would be 5 Stars for sure **
<br>From PA: Glad you like your scope! You may want to try a fresh battery. Scope illumination isn't designed to be as bright as a red dot optic due to power requirements, but we are able to see the illumination outdoors on a sunny day. Some backgrounds may benefit from the black etched reticle in some conditions.

My First Optic Ever For My First Rifle Ever

by -

Finally got to take this to the range! Works great! Lighting is great and the range of brightness are great from no to bright light. Caps snap on and off great and feel nice when they click. Expect a solid pound!
<br>(Also expect your rifle to look extremely sexy.)
<br>Zooming the optic (for my rifle is odd at the least, i have to use an index finger and thumb, pointing my rifle upward, to get the best grip to twist from 1 to 6 and back.
<br>This thing feels like it can take a drop. As a matter of fact, Demitri has a video or two torture testing these products.
<br>While at the range i sighted for 25 yards and while I, myself was off target, i put a 3 finger gap though where my rounds had impacted. Needless to say...The chevron tip was awesome! One is able to refocus on the tip so quickly, its a really nice optic.

If you're on the fence, pull the trigger!

There is a video youtube that breaks down the reticle on this scope really well. The ACSS reticle is amazing. If you line up at 600 you hit at 600. Same back up to zero. I put it on a Colt LE6920 and my 9 yo can hit a torso target at 600 with it. Can't say enough good stuff about the optic. Yeah if it is bright and sunny outside it's hard to see if the reticle is on or not. But when it's that bright out you really don't need the illuminated reticle. Kick it on at 1 power in your house and you have a red dot you can use with two eyes open. As described in the video it is not a precision shooting scope. The cross section will cover a clay pigeon at 500 yards. You can still shoot an 8'' group at 500 yards.

A great optic at a great price

by -

After more that 1500 rounds with this optic it has held up great. I currently have it on an AR pistol with a 12.5in BCM barrel. Despite it being calibrated for a 16in barrel the retical and glass clarity make it easy to make longer shots with a short AR. Further more, the chevron aiming point is incredibly precise, I even put down a .75MOA group with this optic. It has survived not only basic bumps and dings, but also kept zero after drop testing the trigger on my AR pistol. All in all, is not the best scope out there, but the retical and the good quality glass make for a stellar option at the price.


by -

Just Recently purchased this scope and wow am I amazed by the glass clarity and the reticle as well super happy to have purchased this. Idk why people bring up other optics if you wanted to spend 1-2k for an optic then do it already and leave these good priced optics to me lol.

Comparing to my 1200 ffp raptor 1-6, and I must say the Raptors just as clear. At least to my eyes. I need a little more time with it to know for sure, but incredible lpvo even compared to a $1k scopes!

Best 1x6 for the money


At only 1000 rounds so far. Extremely clear glass edge to edge. Illumination is good. Only complaint is battery life. If you leave it on full power brightness over night it will die 😂

Scope good


Really enjoying it so far. Very nice glass. Feels solid to me but I haven't abused it yet. It gets decently bright but I'm in gloomy WA, your mileage may vary out in the desert. Only complaint i have is the first 3 brightness settings are pretty useless, even in pitch black. Maybe they are for night vision but It's not mentioned anywhere that I can see and I don't have Nods to test it. brightness 11 gets pretty bright but maybe not red dot bright. Hasn't been an issue for me. FFP scopes are magic

life saver of astigmatism

by -

weeks ago, I had an attempted break in, but dude failed to enter my place, i was lucky. However, ever since that, I kept flashing back abt the mistakes i made that day.
<br>1. forgot to turn on my eotech.
<br>2. can't find my glasses, so when I look into my eotech, 1/3 of the window is in red mass.
<br>After extensive research, I decided to start with PA 1-6 ffp
<br>1. of course, unlike eotech, no need to turn/on turn off
<br>2. I can clearly see everything without my glasses. Astigmatism is not a problem at all.
<br>3. Most importantly, people say its not daylight bright, it is true. However, I tested in my totally dark bathroom with 1000 lumen rifle light. With eotech, when you turn it on, the default brightness will be washed off. You have to click probably 5 times to reach max brightness, but bc of my astigmatism, max bright+rifle light=red-flower blossom in the window. With PA 1-6, you are 1 click away from the max bright (vs 5 on Eotech). And it is supper clear, no blurry at all.
