Sniper Tools Angle Cosine Level

Snipertools has released the Angle Cosine Level or “ACL”. The level attaches to any rifle and provides both tilt and cant indication. Cant is indicated in degrees in bolt numbering to facilitate quick mental math and releasing the shot to hit on-target.


Description from SniperTools:

The “Angle Cosine Level,” (ACL) has an “Anti-Cant’ device incorporated into it. Opened with a flip of your thumb the all mechanical anti-cant device is displayed in full view and also rotates so that it remains vertical on the Z axis.  This device is not a spirit bubble level. There is no glass vial to break and no liquid to leak out or freeze from cold weather temperatures.  The ACL is impervious to the elements, completely mechanical, rugged and accurate!

The ACL is available for purchase now direct from Sniper Tools for $269.99

    It may just be undue skepticism, but I suspect that anyone who shoots enough to justify this $269 widget is probably already doing the math in their head with practiced precision. That makes this is a toy for wealthy amateurs, which is fine.

      Don’t forget to carry the 1.

      People who need this “widget” probably have a 2000$++ scope, 400$+ scope mount and a rifle that costs as much as the scope if not more. This is hardly an expense in that regard.

    Get rid of the anti-cant device, and bring the price down by at least $100. Then we can talk.

    Who makes the item you have pictures?

    Johnson! Target at Cosine of a 45 degree angle when divided by 2!

    Sir Yes Sir! Adjusting X for the tangent of Y as we speak, Sir!

    SIR! At V=D/T our bullets won’t impact the target, SIR!
