Bobro has announced their release of a new mounting system for 1913 and weaver rails. The complete list of features shown below is what was on the drawing board during product development. Bringing bombproof construction, one hand install and release, auto tightening (no tools of any kind), and complete repeat zero capability, this mount is unlike anything else on the market.

The Aimpoint Comp M4 mount is shown below.




BLAC- BOBRO LEVER, AUTO COMPENSATION - PATENT PENDING

We wrote the desired features on the board in the prototype room (S-93) and designed a system to fulfill all the listed criteria.

1- Must be compatible with any 1913 Specification Rail, to include systems that are out of specification (within reason) and this includes Weaver rails.

2- 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.

3- Must lock with enough pressure to positively attach any device or optical instrument to a rail without movement, static or dynamic forces not withstanding.

4- The rail must not experience any deformation due to user error. This must include synthetic (plastic/polymer/composite) rail systems.

5- 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.

6- Unit must not "shoot loose" due to improper mounting or a mechanical "bottoming out".

7- 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.

8- 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.

9- The pressure must be applied in a linear direction centered in the main body to prevent "cocking" of the mount.

10- It must be easy to manipulate by gloved or fatigued hands.

11- It must be extremely robust, and withstand shock and impact to the system housing.

12- There were others, but by listing them we would compromise our trade secrets.

We at BOBRO felt that the constant massive force was the secret to a truly non adjustable mount that would lock securely, and maintain zero. It would then be truly repeatable. It could not work/shoot loose.
