ACD - Anti-CANT Device
 |
The patented ACD (Anti-CANT Device) is a simple spirit level mounted in an aircraft-quality, two-piece aluminum scope rings that mounts in minuteswithout special tools. Properly mounted, the ACD allows the shooter to visualize and make adjustments for CANT, which experienced shooters recognize as rotation of a scope's crosshairs off a true vertical/horizontal plane. According to the Marine Corps Sniper Manual, compensating for CANT is critical to accurate long-distance shooting: At 1000 yards, 6 degrees of CANT (visualized as 1 minute on the face of a wristwatch) moves the bullet strike 55 inches from point of aim.
Weekend shooters who find varmints a challenge at several hundred yards are no less immune to CANT: 6 degrees of CANT at 100 yards gives the critters a new lease on life by a full ½ inch. Installed on a properly mounted rifle or pistol scope, the ACD uniquely equips the shooter to visualize and eliminate CANT with 100% certainty, 100% of the time.
The ACD has been extensively tested on rifles (does not require modification
to the firearm or scope) and has stood up to heavy repeated recoil without shifting
or detaching. Accuracy is within one-eighth of a degree. Mounts in minutes and
can be placed either on top or below the scope, whichever is most comfortable
for you and where it can be observed by the non-sighting eye.

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

Small and lightweight bubble level

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.

Doesn't quite fit

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.
