Out of stock


The Aimpoint® Cantilever - 180 mount provides a lower 1⁄3rd co-witness when mounted on the AR15/M16 weapon platform. (For your Aimpoint ML2, M2, ML3, M3)
It features the patent pending BLAC throw lever system which requires no manual adjustment to attain a proper, rock solid engagement on a 1913 Picatinny rail.

Design Features

The Aimpoint Cantilever - 180 mount features patent pending BLACK throw lever system which was designed around the following parameters:

  • Must be compatible with any 1913 Specification Rail, to include systems that are out of specification (within reason) and this includes Weaver rails.
  • Must be completely tool and user adjustable free. It needs to be 100% self-contained and mate securely to any rail without the user having to tailor the pressure/engagement position.
  • Must lock with enough pressure to positively attach any device or optical instrument to a rail without movement, static or dynamic forces not withstanding.
  • The rail must not experience any deformation due to user error. This must include synthetic (plastic/polymer/composite) rail systems.
  • Auto Index capability. The device must also index parallel to the bore. The unit must always repeat the forward shift (recoil forces direction of influence) not only to maximize zero repeatability, but to take this step of installation out of the users initial mounting sequence. Index must be redundant.
  • Unit must not shoot loose due to improper mounting or a mechanical bottoming out.
  • The system must incorprate a safety that prevents the lever from being accidentally opened. The safety must be able to be manipulated in conjunction with the lever rotation, so that only one hand is required to open it.
  • The unit will utilize constant force to ensure required pressure in all conditions. The force must be substantial to prevent any shift forward/aft left/right.
  • The pressure must be applied in a linear direction centered in the main body to prevent cocking of the mount.
  • It must be easy to manipulate by gloved or fatigued hands.
  • It must be extremely robust, and withstand shock and impact to the system housing.
  • There were others, but by listing them we would compromise our trade secrets.

    Bobro aimpoint cantilever mount

    I've read nothing but positive reviews on this Bobro product. Rolled the dice and ordered one, couldn't be happier. Self adjusting with outstanding fit and finish. Bobro Engineering is now my go to for all mounts. Ordering through BCM, already having a BCM rifle, I know that thier quality is equal to if not surpassing the top tier manufacturers. And dealing with Bravo Company is always as such. Second to none company providing professional grade products. If they have what I'm looking for in stock, my shopping is complete.

    No Muss No Fuss, Return to Zero

    I took this mount out of the box and tried it on three or four different makes of rails and uppers. It fit them all with no adjustments. No side to side movement, no front to back to movement. Fit and finish are off the scale. I like cantilever mounts and have used the top brands. This one is now my favorite, hands down.

    Amazing !!!!!!!!!!

    Thought I would give this new mount a try. I am glad I did!! Not sure how this product self adjusts on any rail I put it on, but it does. And does it well! I locks tight on all of my different uppers. It repeats zero, as I tested it many times at the range. The quality of machining is outstanding. I hope they come out with a scope mount soon. Very happy with this product.
