Great scope
Great scope I put it on my 308 and it works perfect can see clearly out to 700 yards

I love it
I love this scope, I don’t understand all the bad reviews? I installed it with the factory mounts and rings, I really snugged them down, I shot close to 100 rounds last weekend!!! Never lost zero!!! The 5” sunshade really makes it look BIG. If I had anything negative to say it would be of my own ignorance for not buying the 6-40x50, the 10-40x50 is just a little more power than I need for the target shooting I do. Slightly fuzzy at longer distances... crystal clear at 100yards

The Good, Bad and Ugly Solutions
I purchased the BARSKA 10-40 X 50 for use on a Mosin Nagant build. The 7.62 X 54R round has sizeable recoil and I was concerned about this scope standing up to the sustained recoil of the rifle. I mounted the scope and scope mounts on a Rock Solid Rail and went to the range with two hundred rounds of 182 grain Prvi Partizan Match Rounds. The scope was not zeroing after ten rounds so I taped the Up and Down zeroing knobs with a small plastic screw driver handle after making each adjustment and brought the rounds into the center of the bull in another six rounds. I fired another 20 rounds and went on to another rifle that I am also working up. Everything seem to be OK until my next range session when after 12 rounds the I was all over the target. I checked everything to see if anything was loose and gave up because I couldn't tell. I went home took the scope off and examined the scope and the mounts and reassembled it and went back. I got it sighted in in ten rounds to a 1 inch group. I had some medium Loctite with me this time and took the scope ring screws out one at a time and used the Loctite. Should have thought about it the first time. The screws tightness just didn't hold up to the recoil. After about six hundred rounds, I have not had any additional problems. I am shooting two hundred meters using some 174 grain BTHP Sierra bullets that I reload for the Mosin and holdin one and a half inch groups. I have re-sighted the scope for 150 grain Prvi Partisan rounds and 148 grain Wolf and some 203 grain Wolf rounds. I always lightly tap the knob setting after each adjustment and then tighten the locking ring. In case anyone is interested, the outside diameter of the 50mm optic measured 57.93mm. The scope has performed very well. The problems were a learning curve for me and applying past experience with other scopes. I didn't mention setting the focus but if you follow the instructions and get it set on a clear view and just leave it alone you'll be fine. The Lens Shade works well with this scope. I shoot in a lot of different sun conditions and this was important when I made the purchase. Saves having to buy one and it is an excellent fit. The lens caps are not the best. The problem that I have with them is this kind of popping noise they make. In the dark and out in the field, the sound carries a long way. I recommend a good set of Butler covers. It is a worthwhile twenty bucks or so. I have owned a lot of scopes over fifty years and I have some good ones that cost four times this one. The optical quality on some of them are better. Some of them have failed me. I have been shooting this one for a year now and I am pleased with it. The recoil of the Mosin has certainly put it to the test. It took the recoil of the 203 grain 7.62 X54R rounds better that my shoulder. I have recommended this scope to two of my shooting buddies and after being at the range with me, they have ordered one for themselves. They ordered the Butler lens caps at the same time. My other reason for ordering this was knowing that if it didn't work that I could return it. I am not hesitant to return something that doesn't work. Poor quality is poor quality regardless of the price. I give this four stars but only because of the Lens Caps. FYI! I bought a Gen II BARSKA 10-40 X 50 SWAT and have it mounted on a AR15 build with a 22 inch HBAR barrel and I zeroed it in 5 rounds. Scope in a better quality than Gen I. The Gen II was bought for a different use than the Gen I and the built in lens shade is exactly the fit wanted for the AR. The Lens Covers on the Gen II are worse than the ones on the Gen I. Because the front of the built in lens shade is angled, I haven't found a solution.

Don't understand the 1 star reviews
Bottom line If you purchase this scope get get some locktite and good rings, and it will work great. A little back story a buddy of mine recommended this brand, and yeah I was thinking the same thing you are, "a $650 scope for $225, no something has got to be wrong with this thing." I read just about every review out there on this particular scope and other products. I was getting the scope for my newly purchased remington 700 SPS Tac .308. After my research I said to myself what heck why not give it a chance. Got the scope, got some good rings and locktite, mounted the scope, let it sit over night and took it out the next day. Started my zeroing at 25 yards and got it centered with a few rounds. Took it out to a hundred and was putting rounds on top of each other (where I was aiming of course). Last I took it out to 300 yards and was still putting rounds where I was aiming. I have put about 300 rounds through it in the last 6 months and still spot on. No bull I'm throughly surprised in how my scope handles. Of course do your own research but also take in account the reviews from others. If they used the junk rings that came with the scope, didn't use locktite or duct tape the scope to their rifle yeah I understand the 1 star reviews. For all of you out there that know how to mount a scope give this brand a chance and I'm sure you will be surprised in what you get for your buck. If you don't know how to mount a scope ask a friend or watch one of a hundred U tube videos. Good luck safe shooting.

could Not be happier , gimme a nother one for that money
BARSKA 10-40x50 IR SWAT Extreme Love the scope and the price i think i'm going to buy another one 180 rounds on a 308. rifle (ptr 91, fr) today and it stayed put and true clear focus at 50 , 100 , 200 , 300. yards at any zoom set

I sent it back.
Crystal clear. 40x magnification is insane! Great scope! I'm not sure the red illumimated cross hair is necessary and can't imagine using it. It's so overpowering even at its lowest setting it becomes usless in low light situations but who cares? I just won't turn it on. The scope looks great and performs like something that should cost twice as much. ******* That was before I took it to the range. It hold a zero just fine, very accurate however it does have a haze that intensifies over 34 zoom. On a standard human target at 300 meters you cannot even make out the rings on the target. Having said that it was crystal clear in my house and I live in alaska so it was cold out on range day (20 degrees f) so it may perform just fine in a warmer climate.

Barska Swat Tactical Riflescope
I own & have purchased a lot of scopes in my day, but for the money don't know how u can beat this scope, don't have a bad word to say about. I purchased a different style for my Son's AR & he is equaily satisfied with the product. I actually replaced a Leopould on my 308 target rifle with this scope & wont be replacing it again for quite awhile. Not sure of its distance capabilities as my range only goes up to 600 yards. I'm planning on purchasing another AR type scope for my long range AR 308 in more magnification than I purchased for my Son,as he only shoots at 100 @yards & it will be a Barska!

Schönes klares Bild mit geäzten Mil Dot Fadenkreuz.
Das Zielfernrohr kommt mit einem guten Lieferumfang und macht einen anständigen Eindruck. Das Absehen ist auch bei voller Vergrößerung schön klar. Das Mil Dot Fadenkreuz ist geätzt und nicht zu grob und auch nicht zu fein. Die Türme machen auch einen guten Eindruck. Die Parallaxe lässt sich von 15m bis Infinity einstellen, mit einer180° Verstellung. Hier hätte ich mir etwas mehr Verstellweg gewünscht. Ich nutze das Zielfernrohr auf einem Luftgewehr für Field Target und habe das Zielfernrohr repallaxt, so das es ab 10m Scharf stellt. Somit ist es bei 40x Vergrößerung von 10m bis 25m scharf zu stellen. Bei Field Target misst man mit dem Zielfernrohr die Entfernung zum Ziel. Gerne hätte ich es schon ab 9m scharf gehabt aber dann geht es nur noch bis 21m Scharf. Ich würde das Zielfernrohr von der Qualität im Mittelfeld ansiedeln. Wehr mehr will, muss auch mehr bezahlen. Es ist deutlich besser als die günstigen China- Gläser, kann aber bei den deutlich teureren Zielfernrohren dann doch nicht mithalten.

Solid scope, Could be a bit clearer. seems to have an expiry date at 2 years
Positives: Looks great, Came with everything you need to get it installed. Don't know why people are complaining abut the flip up covers. I think they work great. lasted longer then my Butler creek covers. Had many compliments on it from people thinking I spent $1000 or more. Negatives: Once you go above 32X zoom the lens gets a little foggy looking, but you can still see your target with about 90% clarity. The eye relief is good enough for a high caliber gun, but there isn't any room for error. Without a cheek-rest its tough to get your sights in full view and if you are engaging a moving target it could be difficult to keep it on target. I put about 200 rounds down range on an overcast day and there was always plenty of light for a good view up to and beyond 300 yards. Overall I am satisfied with this scope and I would recommend it to my friends. This is my 2nd Barska scope. Happy with the products overall *******************************************************UPDATE********************************************** 2 years this scope worked great, after my last time out i cleaned my rifle and put it away just like usual. I just picked it up and looked thru the scope and found something inside has ruptured. not sure what it is, but its not on the glass, its inside and doesn't change with zoom. Time to go through their lifetime limited warranty again. both my barska scopes have bit the bucket at two years old.
