I use the ACD Scope Levels on most of my hunting rifles. I own a few of them and love everyone of them.

Once I put one of these on my scope I was very suprised to find how much I was canting, especially at long range. Using this device halved my group size. I am so impressed that I bought another 10, some in 1 inch, some in 30 mm. Every rifle with a scope in my safe has one on. My mates even use them and I now sell them to clients.

This is a beautifully made part that has better fit and finish than most scope mounting rings. It has a high-quality finish, and the fasteners are excellent. However, it is somewhat hard to see with the non-scope eye because it must be positioned on TOP of the scope. One of the other brands that Brownells offers mounts on the side of the scope, but requires a dedicated mounting base. The MWG unit easily mounts to the scope tube and gives you the chance to get the rifle straight (less cant) before firing. I don't think it would be useful in off-hand shooting, but for bench rest and testing, it is wonderful and durable. I ordered three more after trying the first one. This one is high-quality metal, not plastic, and will last forever.

I have not fired the rifle with it installed. However, after dry firing off a bipod and shooting sticks, I think it will be useful and practicable even though it is a little hard to see with the nonshooting eye. I don't want a level that protrudes from the scope. Two criticisms - The screws are installed from the bottom (why?), which makes it harder to install the level than it would be otherwise. I would like to see the sharp corners rounded. Noting the aforementioned criticisms, I would recommend it to friends and associates.

This device will increase accuracy when appropriately installed, just forward of the ocular lens bell housing but behind the rear ring. Yes you must be 10% smarter than the equipment you are trying to operate. But if you are, then you can use the nondominant eye to glance up at the level while in shooting position. And then break the shot. I have one of these on every rifle I own. Even my long-range rifle which I've taken deer or elk without to 800yds. It works when installed correctly in the proper place. The directions are your friend. The only downside is the screw heads are on the bottom. It does take some thinking and technique to install while turning both screw simultaneously for it to tighten down while level. If you shoot a bow, you know what "cant" do to accuracy. Firing a rifle is no different. All the rifles I shoot beyond 200yds with have one of these.

Very low profile and solid construction, have several of these on other scopes.

Last weekend I had a chance to test it at the 300 meter long shooting range and I concluded that this anti-cant device does its job with the utmost efficiency. Bubble level is really sensitive and response is rapid, yet it is affordable for any gun enthusiast. ACD is available both for 30mm and 1" scopes, just keep in mind that you will need a 7/64" (correct me if I am wrong, we use metric system here) hex key to tighten screws.

The ACD works Wells, but my fat wrench inch/pound driver doesn't fit under the scope and around the stock. ACD also doesn't come with an Allen wrench, so hopefully you have the right size. Lastly, the 1inch ACD doesn't quite fit around my 1 inch tube leaving about 1/8 gap on either side when hand tightened.

I’ve been using this product on two precision rifles for several years. It’s well constructed and accurate within 1/8 of a degree. I recommend this product if your serious about long range accuracy and hitting your target. I believe you should stack everything possible in your favor when shooting at distance and for $30 this level will definitely help keep your horizontal hold within 1/8 of a degree.
