Hammer Buffer, Design Summary

BACKGROUND

The firearm from which this invention was created was originally designed and produced in 1957; The CETME Model A. It was later procured, updated, and manufactured by the German Company Heckler & Koch, with the most famous variants being the G3 and MP5. The G3 in particular was utilized world-wide, and is the third most produced firearm in history.

Although these firearms have decades of proven effectiveness, there have been inherent design drawbacks since the original prototypes. The most notable being the lack of “fine tuning” of the firing cycle, and poor ergonomics/performance from the trigger mechanism. These drawbacks however contained the inspiration and part of the solution to both issues. It is unknown how much the original designers recognized the mechanics at play, if at all. It is clear that they were never pursued further by either parent company, and the designs themselves have faded into obsolescence.
