HORUS VISION ASLI
Angle Slope Level Indicator
The ASLI gives the sophisticated marksman a slope indicator and cant indicator in one hermetically sealed unit. Its slope indicator eliminates guesswork in uphill and downhill shots by helping you find true level/ground distance: simply multiply the range to the target by the cosine value shown on the slope indicator. The cant indicator is invaluable in long-distance shooting: it helps keep bullet flight true to your sighted aim. The ASLI attaches directly to your scope, is reversible to accommodate left and right handed users, doesn't need batteries, and comes with a hard rubber cap. Fine-tune your aim with the ASLI.
- Magnetically dampened to quickly halt oscillation for fast readings
- Clear, large numbers for better visibility in low light
- Readings in both vertical angle degrees and its corresponding cosine value
- Versatile mounting for left, right, bubble up or upside down, and high angle grenade launching
- Easy to paint plastic housing to blend ASLI into your scope and gun
- Tested to withstand the repeated G-shock pounding of a 50cal BMG
- Fits a 34mm Scope tubbe and includes 30mm inserts

Customer Ratings & Reviews
Not bad for the price
Took a while to get use to it. The reaction to angle change is a bit slow. And a very bizarre level line placement (to the right of center). Had no issues with mounting it to 30mm scope. A little bit hard to read the numbers during bright sun. It?s not perfect but you can?t beat the value compare to other products on the market. Will buy another one!
This is the product you want, for a respectable price.
This item is a fantastic alternative to the way over priced Badger ACI. It combines the level with the angle and cosign indicator (instead of either / or), and you can get a mount for a rail or for the scope tube. The down side is that the weaver mount fits the ASLI loosely. There is a set screw, but it fits in the locking whole loosely, so the device (at least mine) jiggles. You can either tap a smaller hole or get a bigger screw, and it works well.
ASLI 30mm ring mount
The dovetail on the ASLI body is to small. It just falls out of the ring even after the clamping bolt is tighten as far as possible. Does the same thing with other brands of rings. Called manufacture and I'm stuck with it. They have no more and aren't getting any more. Going to new design. Using shimstock on the dovetail. Quality?????
Angle Slope Level Indicator
A "must have" for the long range shooter ;)
the bubble level having only 1 reference line is actually a plus. the higher in elevation you go, the larger the bubble becomes. what I have done is use the reverse side of the line, the line continued on the opposite side... which can be seen by looking through glass... i take the bubble till it appears beside the opposite line and back it up till it just passes the line on my side. it sucks that you have to peek your head up off the stock to check if adjustments are needed, but with time, memory, and practice i'm already getting it down on my third use. it's not very tactical applicated, but it works! and it's way cheeper, and comes with the level and cosine... no need to buy both separate. but i am afraid i'll find it broke or cracked everytime i pull it out of my bag! time will see... but i like it. you'll see the difference it makes out to and past 200 yards. there's a lot of "internet and range warriors" out there... long distance experts, but if you don't see a guy have a level on his scope, don't listen to any advice he offers! save yourself a lot of wasted ammo, and get better faster with a level scope. cosine works perfectly also... but doesn't nature always.
The ASLI is a well made Gizmo. You will want to mount the "Horus Vision" ASLI on your long range rifle. I works as described.
already put it to the test! Worked great. very useful with the degree of slope, easy to mount. the only thing i would recommend is that there be two vertical set screws to hold the indicator in place. it stays tight to the scope, but the 1 screw didn't hold it in place the first time i shot it (even though i tightened it quite tight) so it flew out of the grooves, i tried to re-tighten it, but i never would stay so i just put a little epoxy on the dove tails and then pinched them. works fine now! very pleased with the product.
Horus Vision ALSI
I have attached one to the scope on my M1A. Because the flat section of the ring is narrow, it may be a bit dicey to place a level on top of it to make sure the ALSI is level with the scope, plus there's only one line marked on the ALSI's bubble level. The numbers as as big as they can reasonably get for an item this size, and it comes with a thick rubber cover with holes that can allow you to attach a short lanyard to prevent cover loss.
Horus ASLI is not as they use to be
this is the third I bought, quality went down, the four screw cracked the plastic, quality is not what it was 2 years ago when there where not the horus logo on it. must have moved their production to china
Horus vision ASLI
Great idea, purchased two.
Side rail is not side rail
I just received my ASLI. I ordered the side rail mount. Well interestingly you cannot mount it to a side rail. You can only mount it to a top rail or lower rail. Completely misleading name here. Also note that some of the screws were over tighten on the plastic frame, I see minor cracking from it. Probably gonna have to return this. It is terrible to pay this much for something to have to mess around with returns and all that stuff. Horus products are grossly over priced and poor quality controls show it.
