The Precision Optic Mount Extended provides a rock solid, repeat zero scope interface for your weapon platform with an additional 0.75″ forward throw than our non-extended mount. It features the patent pending BLAC™lever system which requires no manual adjustment to attain a proper, rock solid engagement on a 1913 Picatinny rail.


The Precision Optic Mount features patent pending BLAC™ 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.

    Want the best?

    I have several unibody mounts for scopes...if your mounting a scope on an AR platform, Bobro is the best bet. Good looks, rock solid attachment, and perfect return to zero...what's not to love. I have had ADM, GG&G, and Larue Tactical, but I always come back to Bobro. Bobro is my first choice with these type of mounts every time.

    I have two of these now and love them. No adjustment needed, rock solid lock up, and excellent return to zero. I wouldn't trade my Bobros for any other mount on the market. Thanks to Bauer Precision for excellent service.
