This is a great set of sights. Easy to mount and works great. Great quality!!
Definitely a good deal, great product, mounted very easily, and look awesome on my new AR build.
These 45 degree Angle Iron Back-up sights are top quality and complement my custom build very well. You cannot go wrong with these Back-up Iron Sights.
Sure you can pay more ... but you won't get a whole lot better BUIS. These were excellent for the money. Strong, well made. I would buy the same product again.
The processing and shipping were very fast from AT3, and they did a good job on the return too. These sights are going to be fine for the vast majority of users, you guys who shoot once or twice a month. As I have an at-home range and shoot almost every day, They did not meet my quality requirements and I did not keep them. They do the job ok, but you get what you pay for. The mounts to the gun are fine. The internal parts are just ehhh, The front sight post is not rock solid or high-quality machining, and the back sight post is also a bit loose within itself.
I purchase online from several vendors. My experience with AT3 was remarkable. The product was high quality. The price was great. And it was delivered ahead of the scheduled time. I'm not sure it could get any better than that!
Good quality sights, study,heavy built and works well.
Excellent sights. Work wonders using a full size scope. The transition from scope to sights is a lot easier and faster with these. Operation of the sight is simple and quick for zeroing. Construction is very tough. Definitely a must have for anyone wanting a full size scope and wanting back up open sights.
Compares with the big $ brand that I own. Great sight. .won't be the last set it buy.
Awesome sights for a great price
Got the part guick and in tact. Very easy to order. I will be making more purchases in the future. Thanks guys!
It's really hard to beat the value of these sights. They are solid and well-built, install easily, work as expected, and are inexpensive compared to other offset sights on the market. Just a great deal.
I just installed these on an 20" .223 Wilde AR with a Primary Arms 6x scope. The transition from far to near (and back) is seamless and easy on the eyes. These iron sights are very tight and accurate. Minimal adjustments required to zero in at 50 yards right out of the packaging. Fast adjustment to zero at 100 yards, after which the scope takes over. Simple, rugged, and easy transitions. Very pleased with this product - may get another set for another AR build. Excellent service from AT3 - Thank you!
Have worked great. Only thing that might be improved is to add a small wheel on front sight so you don’t need a small separate tool to adjust it up and down.
I really like these sights. Nice and sturdy construction.
Installed these sights on my AR couldn't be happier with them. Zeroing was simple, 12 rounds at 25 meters shot a 3/4" 3 round group. Solidly built high quality product would absolutely recommend to anyone whose looking for a reasonably priced quality BUIS. Fast shipping, I will do business again with AT3 Tactical.
Good quality product and fast shipping
Very well built. Offset design allows for fixed sights that are not as finicky as flip ups. Delivery was fast.
Great service....fast delivery...good reliable. BUIS
Great item, and will be looking forward to installing the sights on my AR-15 Rifle build. Will also be doing more business with AT3 Tactical in the future. Great product, quick delivery, good job AT3 Tactical group.
Bought the above items and they arrived in a very timely manner.
Part fit-up was very simple and parts worked as described!
the machining on the adjustable portion of the front sight is clumsy, and it is difficult to get the pin to lock in at some elevations. the rear sight has some movement in the carriage at elevations above zero.
I bought these for a Barrett rec7 and they're perfect. Very tough and solid feeling. Would buy again!
The sights came very fast. They mounted to the gun as advertised. A nd when I sighted them in they worked great. Thanks so much for a great product and great service.
As described on the site, delivered quickly.
Great quality product
Well made and finished, great price and service. Adds 150g / 5.3 ounces, as these are solid pieces.
Real sturdy and seems to be a great purchase
Decent for backup sights could be some improvement on rear elevation wheel
Love the product. Always what is expected or better
I just received it, and it looks and mounted great. I have not sighted it in yet.
These sights are robust and we'll constructed and quickly installed and easily adjusted.They held their zero in the field and for the purchase price are a true bargain! I highly recommend them!
Great quality sights for the price, would recommend them to anyone.
Heavy duty, oiled up and ready to go. Yet to zero them but arrived in good shape.
Awesome offset sights. Almost battle sight zeroed right out of the package. Would definitely recommend.
I went with this sight combo mainly due to the price and close similarity to many high dollar sights out there. The sights are a solid sturdy construction and mount easily. I recently zeroed them and found it very similar to traditional iron sights, as long as you have a good consistent cheek stock weld at the 45 degree it's easy to group rounds, more practice with the offset will only increase the comfort level of using them but they were super easy to use. I wanted the sights to be fixed so I wouldn't have to flip up a sight in an emergency, with that said, they do take some impact if you lay the rifle down on the side they protrude from. I used blue thread locker when installing them to help them stay put even more but only time will tell if rough use will knock these sights off zero. Great price and lightening fast shipping. I will definitely refer these sights to friends and use AT3 again. If you don't have a front sight adjustment tool its definitely something you want to add unless you don't mind scratching the finish off of the front sight while adjusting it.
Great sights at an unbelievable price. They seem to be built like a tank and are easy to adjust. Great product!
Just what I was needing a for my ar with a scope!
They fit well, look good, and serve their purpose. Couldn't be happier with them, especially at a fraction of the cost of others
I purchased the 45 degree offset sights and I love them. they are a great addition to my AR-15. Great for close range engagements. Great quality at a great price. Couldn't be happier. Fast shipping.
These are solid sights. Bought two sets I'll probably order two more. Keep up the good work
Awesome product and awesome response on shipping!
Awesome sights,fit perfectly. Great service as usual!
Sights install great and are made of good quality. Only issue I have is that the rear sight seems to be just a pin hole size peep. I imagine it would be hard to pickup your target in stressful situation. If the view portion of the sight was a little larger hole than a pin, than these would get 5 stars. Great fit and finish.
Great set of offset sights, just want I needed to complete this build. The service from AT3 Tactical is fantastic. Prompt delivery
They fit just fine on my Bushmaster C-15. Haven't been to the range yet to sight them in but I can transition from my optics to them with ease.
Great customer service. Thanks AT3 Tactical.
So far so good! I love these sights. They went on easy and zeroed easy. I have only had them for a week, but they seem to be made well. I would recommend these as BUIS to anyone looking for BUIS at a great price.
My 45 degree back up sights werea waste of money! The bolt hole was stripped in the peep hole side. The front post was extremely loose and impossible to accurately sight in. Won't waste my money ordering Chinese junk here again
Received my 45 degree back up sights yesterday. The peep hole side was stripped, and won't bolt on. This something that should have been avoided prior to shipping. They didn't inspect before shipping, and now it will most likely take another 2 weeks to ship them back, and send out new ones. Not to mention I'll have to take time off work to go to the post office to return them. I can't even call them because they are only open Monday- Friday, and I don't have any of those days off, or have cell signal at work. It would have been cheaper to pay double at the store! Not happy at all!
Recieved these offsets & saw the rear aperture bolt wasnt square. It looked tweakish but the fsb was good. Contacted customer svc. & griped they said they will replace. Mounted them anyway because of time constraints & at the range yesterday dead on no adjust. Multiple rounds same hole @ 50 yd. Line. Will recomend to anyone wanting tough as hell back ups
I had been searching the web for some buis for use on my spr without breaking the bank and found these. I sighted them in at 50 yds and then moved on to 100. These buis are amazing and the quality is great.
You will not be disappointed in this purchase.
I love the at3 transititional 45 deg. sights. This is my second set . I plan to buy a set for all 23- ARs I own. like it, buy it , keep things consistant, this will keep you quick and accurate.
Well made. Easy to zero.
Awesome product, I didn't even have to remove my scope to install them. Plus if they are good enough for troops in Iraq, as an Iraq vet myself, they are good enough for me. I love them and even recommended them to my friends.
FRONT SIGHT HARD TO ADJUST. TIGHT FIT. REAR SIGHT LOOSE IF NOT AJUSTED ALL THE WAY UP OR DOWN BUT THEY DO WORK.GET WHAT YOU PAY FOR
Very high quality . The first rear sight got damaged in shipping as soon as I saw this I called in and a very nice lady named Laura had me a new rear sight shipped out that day . It came in in perfect shape will def use them again for parts
The sight adjustment wheels are loose and will not hold corrections
Sights seem very high quality ! My rear sight got damaged in shipping . I called them told them it was bent they sent me a new one no questions asked . Great service will def use them for parts again . Thank you
price was right service was prompt. thanks
Five Stars... Straight out of the box, you can tell these are worth every penny and then some. They're easy to install, adjust, and zero. If you're looking for something that will be there for you when you need it, I'm fairly comfortable in saying you've found it. Spend the little extra money on the adjustment tool, unless you already have a metal one, because the positive-retention post in the front sight will likely chew up anything plastic and spit it back out at you. Overall, I'm honestly impressed. AT3 has earned my business and respect.
I purchased these 45 degree back up iron sights for my AR-15 build. So far they look great and stay out of the way, I have not had a chance to go to the range to try them out yet.
A few scratches not sure if it was at3 shipping or being left with a friend for months; they look great; work great on my airsoft I'm sure they will work great on the 15 when it's complete. Very happy
First impression: These sights are solid! No slop, nothing loose, and they're beautifully finished. The rail mounts are low enough to fit under even a low scope (which is what offset sights are for, right?) and they mount easily with a flat-blade screwdriver - I used my Learherman.
The front sight can be mounted on a railed gas block, which of course you can't with polymer sights. The adjustments are all at the rear sight, where they should be for speed and ease of use. Both windage and elevation change easily enough, but the detents are solid and you can tell nothing is going to slip.
Flipping the peep aperture from large to small takes a bit of effort, but that's far better than the sights I had where it flipped by itself!
The only thing that seems like it might be a bit awkward is how far they project to the side - but that makes them easy to sight through. You can rotate from scope to offset sights in a moment, keeping the same cheek weld on your stock.
On the whole, these are beautifully made and an awesome value for the money. Compare to other sights costing $80-200 and you'll agree! Got two sets, will definitely get more.
This product is no different than the ones sold on amazon for 25$.
These are the same sights on amazon for $25.00 shipped. the long range sight aperture is incorrectly machined, so its gathering light on the wrong side making the front sight tower blurry. not very impressed, and I haven't even put them on the gun yet.
I installed one of the two sets on my firearm and gifted the other!
These are the best offset sights I have ever found!
These are quality sights!
I purchased two(2) sets of these one for me and one for a gift.
Exactly what I wanted. Well made and easy to sight in.
I installed the iron sights on my AR15 and I shot my gun at 50 yards and I didn't have to touch them. They were right on . My nephew served 25 years in the Army in special forces and he picked the gun up and it was right on for him and he liked the way they performed.
Very well built, dialed em with in a few shots. Very happy with them, great price great product. Got them late last fall, today was the first time I got to try em out. Love em.
Awesome company to work with!
Full metal, solid mounting.
The sights were delivered quickly and the fit and finish were perfect. Sighting was a breeze, but most of all I am pleased with how solid these sights are. AT3 is spot on with this product.
The 45 degree sites is exactly what I needed for close range shooting. Nice high quality adjustable sites for a great price. Thank you
My sights came in and were well made and installed easily. My husband ordered a pair that night. Great sights for the money.
great buy, easy to install and solidly built. best I have seen for the price.
They look great. Seem very rigid and sturdy on the rifle. Waiting for warmer weather to test them out. I would buy again from AT3.
The sights were very easy to install and work well.
Everyone should have these on their rifle if you're using a low rise scope. I mounted a 4x16 Nikon M223 scope on P series rings to alleviate parallax error. Sturdy and feels like part of my free float system.
