A barrel system for a paintball marker including a breach removably connected to the paintball marker and a composite front detachably connected to the breach. The composite front of the barrel system includes a hollow bore through which a paintball is propelled, a non-metallic inner layer surrounding the bore, and a non-metallic outer layer surrounding the inner layer. The non-metallic inner layer is preferably manufactured from a plurality of unidirectional graphite fibers embedded within an epoxy resin. The non-metallic outer layer is preferably manufactured from a plurality of graphite fibers that are woven together and embedded with an epoxy resin for surrounding and reinforcing the inner layer. The non-metallic inner layer of the composite front is smoothly and continuously tapered to cause the hollow bore to be tapered from a relatively narrow diameter to a relatively wide diameter in the direction of travel of the paintball.

I claim: 1. A paintball marker from which a paintball is to be propelled, said paintball marker comprising a hopper in which paintballs are stored, a hollow breech communicating with said hopper to receive a paintball therefrom and a barrel having a first end to be detachably connected to said breech and an opposite exit end from which the paintball is ejected from the paintball marker towards a target, said barrel having a hollow bore with a length extending from said breech to the opposite exit end of said barrel to provide a guide path along which the paintball travels and a layer of non-metallic material surrounding said bore, wherein at least a portion of said hollow bore is continuously and uniformly tapered from relatively narrow to relatively wide in the direction of travel of the paintball towards the target, the continuously and uniformly tapered portion of said hollow bore extending uninterrupted for at least half the length of said bore, and a plurality of non-metallic fibers embedded within the layer of non-metallic material surrounding said bore. 2. The paintball marker recited in claim 1, wherein said plurality of non-metallic fibers extend unidirectionally through the layer of non-metallic material surrounding said bore. 3. The paintball marker recited in claim 2, wherein said plurality of unidirectional fibers of said layer of non-metallic material are arranged in parallel alignment with one another in the direction of the longitudinal axis of said bore. 4. The paintball marker recited in claim 2, wherein said plurality of unidirectional fibers run continuously through said layer of non-metallic material. 5. The paintball marker recited in claim 2, wherein said plurality of unidirectional fibers of said layer of said non-metallic material are manufactured from graphite. 6. The paintball marker recited in claim 2, wherein said layer of non-metallic material surrounding said bore within which said plurality of unidirectional fibers are embedded is a resin. 7. The paintball marker recited in claim 1, wherein said layer of non-metallic material surrounding said bore includes a plurality of woven fibers running therethrough. 8. The paintball marker recited in claim 1, further comprising a metallic coupler surrounding the first end of said barrel, said metallic coupler enabling the first end of said barrel to be detachably connected to said breech. 9. The paintball marker recited in claim 8, also including a bump projecting outwardly from said metallic coupler to prevent said barrel from rolling over a flat surface. 10. The paintball marker recited in claim 1, further comprising a coupler carried by said barrel to enable said barrel to be detachably connected to said breech, said hollow bore extending through each of said coupler and said barrel, and the uniformly tapered portion of said hollow bore extending completely through said barrel from said coupler. 11. The paintball marker recited in claim 1, wherein the continuously and uniformly tapered portion of said hollow bore has the same shape at each cross section along the entire length thereof. 12. A paintball marker from which a paintball is propelled, said paintball marker comprising a hopper in which paintballs are stored, a hollow breech communicating with said hopper to receive a paintball therefrom and a barrel detachably connected to said breech, said barrel having a hollow bore along which a paintball travels, wherein at least a portion of said hollow bore is continuously and uniformly tapered from relatively narrow to relatively wide in the direction of travel of the paintball towards the target, the continuously and uniformly tapered portion of said hollow bore extending uninterrupted for at least half the length of said bore, an inner layer surrounding said bore, and an outer layer surrounding said inner layer, one of said inner and outer layers of said barrel having a plurality of unidirectional fibers embedded in a non-metallic material and the other one of said inner and outer layers of said front having a plurality of fibers that are woven together and embedded in a non-metallic material, said tapered bore having the same shape at each cross section along the length thereof. 13. The paintball marker recited in claim 12, wherein the continuously and uniformly tapered hollow bore of said barrel tapers from relatively narrow to relatively wide in the direction of travel of the paintball. 14. The paintball marker recited in claim 12, wherein said barrel has a front at one end thereof through which the paintball is ejected and a coupler at the opposite end to enable said barrel to be detachably connected to said breech, said hollow bore extending through each of said front and said coupler, and the uniformly tapered portion of said hollow bore extending completely through said front from said coupler. 15. A paintball marker from which a paintball is to be propelled, said paintball marker comprising a body at which a supply of paintballs is carried and a barrel, said barrel having a first end, a coupler located at said first end to be detachably connected to said body to receive a paintball therefrom, an opposite end, and an exit opening at said opposite end from which the paintball is directed towards a target, said barrel having a hollow bore with a length extending from the coupler at said first end to the exit opening at said opposite end to provide a guide path along which the paintball travels from said body, and a layer of non-metallic material surrounding said bore, wherein at least a portion of said hollow bore is continuously and uniformly tapered from relatively narrow to relatively wide in the direction of travel of the paintball towards the target, the continuously and uniformly tapered portion of said hollow bore extending uninterrupted for at least half the length of said bore. 16. The paintball marker recited in claim 15, wherein the continuously and uniformly-tapered portion of said hollow bore of said barrel extends for the entire length of said bore.
