Paintball projectile drop compensator
View Patent ↗A barrel attachment for a paintball gun is provided to impart spin onto a paintball exiting the barrel of the paintball gun thereby providing projectile drop compensation. The attachment is made up of a structure having an elongated aperture with a first end that attaches over the barrel of a paintball gun thereby extending the barrel. A second end of the attachment has an open passage that is disposed at an angle to the centerline of the barrel so that a spin is imparted onto a paintball fired from the gun as it passes through the open passage.
1. A paintball gun having a barrel and barrel spin attachment that induces spin onto a paintball exiting the barrel of the paintball gun, the attachment comprising:
a structure having first and second end portions, said first end portion having a substantially cylindrical cross section and an aperture along a first longitudinal reference axis, said first end portion attached to the barrel of the paintball gun; the structure including an open semi-cylindrical cavity adjacent the second end portion, said cavity is adjustably displaceable towards the longitudinal reference axis of the paintball gun barrel.
2. The barrel spin attachment of claim 1 , wherein a paintball exiting the barrel will contact an inside surface of the cavity as a paintball passes therethrough.
3. The barrel spin attachment of claim 1 , wherein an inside surface of the open semi-cylindrical cavity imparts friction to a paintball passing therethrough.
4. The barrel spin attachment of claim 1 , wherein an inside diameter of the second end portion is substantially equal to a diameter of a paintball.
5. The barrel spin attachment of claim 1 , wherein an inside diameter of the second end portion is less than a diameter of a paintball.
6. The barrel spin attachment of claim 1 , wherein said first end portion is aligned with a centerline of the barrel, and said open semi-cylindrical cavity is set at a slight angle relative to a longitudinal axis of the paintball gun barrel.
7. The barrel spin attachment of claim 1 , wherein the structure comprises an elastomeric material.
8. A paintball gun having a barrel with an attachment for imparting spin onto a paintball exiting the barrel, the attachment comprising:
first and second ends, the first end connected to the barrel of the paintball gun and includes a barrel attachment portion that transitions to a spin portion having a c-shaped cross section, the spin portion is adjustably extendible into a trajectory path to make contact with the paintball exiting the barrel.
9. The attachment of claim 8 , wherein a paintball exiting the barrel will contact an inside surface of the spin portion as a paintball passes therethrough.
10. The attachment of claim 9 , wherein the inside surface of the spin portion imparts friction to a paintball passing therethrough.
11. The attachment of claim 8 , wherein an inside diameter of the spin portion is substantially equal to a diameter of a paintball.
12. The attachment of claim 8 , wherein an inside diameter of the spin portion is less than a diameter of a paintball.
13. The attachment of claim 8 , wherein said barrel attachment portion is generally aligned with a centerline of the barrel, and a longitudinal axis of said spin portion is set at an angle relative to centerline of the paintball gun barrel.
14. The attachment of claim 8 , wherein the structure comprises an elastomeric material.
