I have loved this scope until this year when I had to use it in heavy snow. The laser aperture got plugged with snow and wouldn't reflect a dot. Had to carry my shotgun upside down whenever I went under snow-laden trees. Is there some type of cover to protect the aperture and flip off easily?

We had this camera for a long time.  The zoom was amazing then all of a sudden after several years it started to get a black dot in every photo. We decided to purchase a new one and in less than a year the black dot is appearing.  We will be switching brands on our next purchase!

It is sturdy and easy to attach.  The problem is that the dot is very fuzzy and makes it hard to sight in.  I have not used it on range yet .  I advise not to buy this scope

This scope changed my pellet rifle from a toy to a nice air rifle. Only lasted about 1200 shots before scope was all over the place. Going to have to spend real money for a real scope. Like the one piece scope mount.

***Update 12/2015.....scope broke again.  Selling it.  I need a reliable scope.
***Update 10/2015.....Owen got back to me and made good on the issue (almost three years....that is a long warrantee!).  Scope is 100% working now.  Revised three-stars to four. ****

OK Scope.
Has great features.
I've had it for almost three years now.
Time to send it in for warranty service....anybody know how to contact OWON?  I have not had any luck getting in touch through www.owon.com.hk

Anyway, here is my review:
What I like (above and beyond the list of features already mentioned in other reviews)...this is why I bought it:
*I could afford it. :-)
* I bought it with the optional battery....is a 5000mah Lithium.  Over two hours continuous use!
* I love the fourier Transform capability w/HUGE buffer....not a spectrum analyzer, but can provide limited capability for <75mhz.
* Remote Ethernet access and desktop access tools is great.  VGA is cool also, HDMI would be better.
* Very portable and nice big/bright screen.
* Can power USB-powered tools (my DDS Function Generator)....imagine that!  Portable battery-powered 8-inch O-Scope that can power other USB assessories for field work!

What I do not like:
SLOW refresh rate...not a big deal for my work.
"Vector" mode does not work in X/Y mode.
Setting the vertical Volts/Div knob is broken.  Sometimes increase when turned clockwise, will sometimes DECREASE....most of the time is random up/down when I turn adjust knob.  It makes the scope very hard to initially setup a trace.
Time to send it in. :-/  I'll keep it...am happy otherwise.  Will update review about OWON service.
Kind of "toy-like" build look/feel.  But nothing has broken yet, so I suppose it is OK.
Their is no peak-to-peak voltage reading for a waveform.  Volt-average always reads way below (unless square wave) with what is plotted on screen.

Would have given it four-stars if not for the failing horizontal knob and hit-miss features (vector, peak-to-peak voltage, others).  Will be trying to contact Owon about Volts/Div setup issues....see if their 3-year warranty is for real or not.

The Long stock screw fell out somehow without me realizing it until recently. I wondered why it seemed like there was no way to dial in the scope so never really used it.  Until recently got it out and started messing with it did I find that the receiver with the scope wobbled up and down because there was no screw holding in the rear...  Just make sure all the pieces are assembled correctly.

I'm a bit conflicted with this scope. I love the build quality, and the optics clarity at parallax 0. The features you get for the price make it very economical. My issue is with the parallax. This scope is built to shoot at 50 Yards, but has Bullet Drop Compensation for 50, 75, 100, 150 yards. I have only tried at 50 and 100, so I cannot speak to the other ranges. At 50 yards, the optic is crystal clear...the reticle is perfect, and the target is in sharp focus. At 100 yards, my eye cannot focus on the reticle and the target at the same time. If I focus on the bulls-eye, the BDC circle is a blurry mess. If I focus on the circle, I can no longer see a 1MOA bull. At 100 yards, I get a headache after looking through the scope for more that 5 minutes.

I understand this seems petty for a rimfire scope. And had it not come with the BDC reticle, I would ignore these impressions. The issue is, the scope is advertised to shoot up to 150Yards...that's 3x the range I am able to use it for. If it was a simple cross-hair that worked at 50 yards, I would be happy...but it is touted as a scope that can go from 50-150 without adjustment.

Edit: I have tried a number of scopes (Nikon, Vortex, Leupold, Burris) and all have the same issue. I think I need to see the eye doctor. There is nothing wrong with this scope. In my extended family, we have 7 Nikon Prostaff scopes, and they are all very good. Buy with confidence. If you have trouble with clarity, take off the scope cap, or see the eye doctor.

I am a big fan of primary arms and owned a 1-6x before upgrading to this as I wanted more magnification.  The 1-6x worked great on my Ar15, i was able to hit 1/2 inch groupings at 100yrds all day.  However, when I put the 4-14 on, I went through 100rds trying to sight it in then realized the scope just was not holding Zero and the reticle was cocked slighly (and moved very very slightly each shot).  I guess the recoil was too much?  It's on a .223 platform like the scope says it's intended for so I think i just got a defective scope.

I just put a return request in and I hope Primary Arms honors it as the only reason I want to return is the fact that I got the luck of the draw on a defective scope.

Otherwise the scope itself is very nice for the money. I would have kept it if It didn't lose zero on every single shot.

The scope is great but the battery cover fell off when using it & its lost forever. I've tried contacting Barska through their website & Facebook page but never got a reply so consider customer service from the manufacturer to be non existent.

I had been looking for a telescope for quite some time and was very interested in both this scope and the Orion SpaceProbe 3 Equatorial.  After many days of weighing the pros and cons of both scopes, I chose this one.  After the easy assembly because of the clear instructions, I was very excited to start looking for things.  Sadly, one of my clumsy family members knocked it over (it's pretty sturdy, I don't know how he did it) and from even my lack of experience I could tell it was out of collimation.  After 3 hours of tediously turning the screws back and forth and trying to see if the lenses were lining up in my DIY collimation cap made from a film canister, I was nowhere.  I was very upset and decided to do more research into collimation.  I found a lifesaving product here on Amazon, A laser collimator that would hopefully work with this bird-jones design.  After recieving the laser and putting it to use, I had finally collimated this scope.  I now enjoy all the aspects about this scope but my one warning is this.  DO NOT GET THIS SCOPE FOR A CHILD!  Even me, a 16 year old is still not 100% sure about the collimation of this scope.  Overall, this is a wonderful scope for someone who likes to figure things out by doing them and not by the instructions since they tell you almost nothing about the collimation of this scope except which of their expensive collimators to buy, but if I had a second chance I would have gone with a way simpler scope.

Great scope I love it, but afternoon just 1 day of shooting with it. The retical started to rotate. It's at a 30 deg angle.
The center is still accurate but the cross hairs are way off. So just tilt the gun. I have not contacted the seller yet !

Great scope for the price but you have to take the whole scope apart just to get the clips off. I wanted to put new clips on because the scope was sliding back on my rail.

I'm updating my review. In my previous review I stated that I love this scope, and I still do. The reason I'm giving it 3 stars is because I have to send it back. The reason I'm sending it back is not because it is not a good scope. I'm sending it back because there is no way to mount the thing on a rail without it moving. The screws simply do not go into the slots on the rail. The only thing you can do is clamp the scope on the rail and unfortunately that does not work. No matter how much I tightened the clamps, the scope would move during firing. Unfortunately this will not work and essentially makes the scope unusable. Make sure you are ready to deal with this fact. THE SCOPE ONLY CLAMPS ON THE RAIL AND NOT IN THE SLOTS!!!!!! Great scope, lousy design.

The magnification is nice, it can technically be used to see far away, however that magnification comes at the cost of clarity.  I had returned a Bushnell Banner 6-18x50mm to get this scope because I wanted something with mil dots for range estimation, I figured this would fit the bill but it does not.  To be fair, I haven't shot the rifle with this scope on it, but the sight picture becomes so hazy at anything > 18x that it's not worth it.  I'm submitting a return for this today, I guess if you only wanted to use it up to 18x then it'd be fine, but why did you buy something that's 6-24x?

The scope is of good quality, and easy to use and I like it very much. The tripod is a horse of a different color! It is more shakey than I am and I  am 73 yr. old! Needles to say, It went into the trash. I would recommend this scope, but start looking for a new tripod.

Wanted to love this scope but alas it was not to be.  The elevation adjustment was very hard to turn and at 25 yards was shooting 4 inches low and adjustment was maxed out as others have reported.  Changing the zoom also moved the point of aim. This scope was a replacement for the Center Point scope that came with a 22 cal Crossman Shockwave Nitro piston rifle. The Hammers scope is being returned to Amazon.  I mounted a CV Life scope also from Amazon and had no problems zeroing the rifle.
