Claims
- 1. For use in a firearm having a barrel and a locking element formed at the proximal end of the barrel, a bolt assembly comprising:
a bolt carrier; a bolt head; a connecting device operatively coupling the bolt carrier and the bolt head; an elastic sleeve mounted on the connecting device and having an expanded state and a compressed state, the elastic sleeve contacting the bolt carrier and the bolt head in the expanded state to thereby substantially prevent relative longitudinal movement between the bolt head and the bolt carrier; whereby compression of the sleeve from the expanded state toward the compressed state permits relative longitudinal movement between the bolt head and the bolt carrier; and means for damping vibrations of the elastic sleeve.
- 2. A bolt assembly as defined in claim 1 wherein the bolt carrier and the connecting device define an annular space, and the sleeve is sized to enter the annular space when suitably compressed to permit relative movement between the bolt head and the bolt carrier.
- 3. A bolt assembly as defined in claim 1 wherein the means for damping comprises a forward portion of the bolt carrier, the forward portion of the bolt carrier and the connecting device define an annular space and the sleeve is sized to contact an inside periphery of the forward portion of the bolt carrier adjacent the annular space when uncompressed.
- 4. A bolt assembly as defined in claim 1 wherein the sleeve comprises a spring plate.
- 5. A bolt assembly as defined in claim 1 wherein the sleeve includes a slit to permit compression between the expanded state and the compressed state.
- 6. A firearm comprising:
a barrel with a locking element at the proximal end of the barrel; a bolt carrier; a bolt head; a connecting device operatively coupling the bolt carrier and the bolt head; an elastic sleeve mounted on the connecting device and having an expanded state and a compressed state, the elastic sleeve contacting the bolt carrier and the bolt head in the expanded state to thereby substantially prevent relative longitudinal movement between the bolt head and the bolt carrier, whereby compression of the sleeve from the expanded state towards the compressed state permits relative longitudinal movement between the bolt head and the bolt carrier; and means for damping vibrations of the elastic sleeve.
- 7. A firearm as defined in claim 6 wherein the means for damping comprises a forward portion of the bolt carrier, the forward portion of the bolt carrier and the connecting device define an annular space and the sleeve is sized to contact an inside periphery of the forward portion of the bolt carrier adjacent the annular space when uncompressed.
- 8. A firearm as defined in claim 6 wherein the sleeve comprises a spring plate.
- 9. A firearm as defined in claim 6 wherein the sleeve includes a slit to permit compression between the expanded state and the compressed state.
- 10. For use in a firearm having a barrel and a locking element formed at the proximal end of the barrel, a bolt assembly comprising:
a bolt carrier; a bolt head at least partially received by the bolt carrier; and an elastic sleeve mounted on the bolt head and having an expanded state and a compressed state, the elastic sleeve contacting the bolt carrier and the bolt head in the expanded state to thereby substantially prevent relative longitudinal movement between the bolt head and the bolt carrier, whereby compression of the sleeve from the expanded state towards the compressed state permits relative longitudinal movement between the bolt head and the bolt carrier; wherein a portion of the elastic sleeve engages an inner surface of at least one of the bolt carrier and the bolt head when the elastic sleeve is in the expanded state.
