Abstract
The invention is a cooling block that is added to a semi-automatic rifle to improve the cooling of the barrel. The cooling block is designed to fit into an air-cooling shroud and sit tightly against the gun barrel. The tolerances for the contact surface between the cooling block and the outer gun are critical for optimal cooling, and the block is designed for easy replacement to provide more continuous cooling.
Claims10
A metal block cooling system that improves precision of a semi-automatic rifle comprising:
- A) a metal cooling block having a block height, a block width, and a block length,
- B) said metal cooling block having a halved cylinder cutout along said block length, said metal cooling block having desirable thermal characteristics for heat transfer and heat absorbing,
- C) said metal cooling block having a pin positioning hole on a surface opposite of said halved cylinder cutout,
- D) a shroud positioned above said rifle barrel and attached to said rifle barrel by a pair of shroud spring clips,
- E) said shroud incorporates a block positioning pin,
- G) said metal cooling block is positioned on said rifle barrel according to:
- i) being between said pair of shroud spring clips,
- ii) by placing said halved cylinder cutout on top of said rifle barrel, and
- iii) said block positioning pin being inserted into said pin positioning hole,
- H) whereby said metal cooling block provides additional cooling when said semi-automatic rifle is fired and said metal cooling block provides an improvement in shooting precision by 19% to 35% inclusive.
