Abstract: A magazine floor plate for a firearm magazine includes sidewalls that extend vertically from floor plate and define an interior cavity for accommodating a portion of the firearm magazine. The sidewalls include a first parallel longitudinal sidewall, a second parallel longitudinal sidewall, a first parallel traverse sidewall, and a second parallel traverse sidewall. The magazine floor plate further includes a locking mechanism for insertion between the firearm magazine and at least one of the sidewalls when the interior cavity accommodates the portion of the firearm magazine. The first and second parallel longitudinal sidewalls have a length greater than the firearm magazine.

Abstract: An internal pulse damper for use in a fuel rail for an internal combustion engine. The damper is formed from a length of tubular metal stock having a flat oval cross-section and ends flattened by crimping to form a captive-air pillow. The end crimps are improved through use of tooling to eliminate a creased sidewall area vulnerable to stress failure in prior art pulse dampers.
