Abstract
A semi-automatic or automatic rifle comprising a barrel attached to and upper receiver and including a compressible bolt carrier extension system. The compressible bolt carrier extension system includes a bolt carrier, an extension spring, two pins, and a reciprocation bolt carrier extension piece. As a whole, the compressible bolt carrier extension system makes possible the use of elongated upper and lower receivers to be used for chambering long-action or other center fire cartridges for use with AR rifles such as the M-16, and M4 etc., eliminating the need for any buffer or buffer tubes other than those commercially available. A further advantage of the compressible bolt carrier extension system is the reduction of felt recoil as the system fully loads during the recoil stroke as it pushes against the buffer absorbing additional recoil energy. The system can be incorporated into firearms using a variety of cartridges.
IPC Classes ?
- F41A 3/26 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks semi-automatically or automatically operated, e.g. having a slidable bolt-carrier and a rotatable bolt
- F41A 5/20 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock gas-operated using a gas piston arranged concentrically around the barrel
- F41A 3/12 - Bolt action, i.e. the main breech opening movement being parallel to the barrel axis
- F41A 3/78 - Bolt buffer or recuperator means
- F41A 5/26 - Arrangements or systems for bleeding the gas from the barrel
- F41A 5/18 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock gas-operated

Abstract
A suppressor assembly for a firearm including a barrel, a bore and a muzzle end. The suppressor assembly may include a gas block mount positioned about the barrel, and outer tube configured to be attached to the gas block mount, and a baffle configured to be attached to the muzzle end of the firearm. The baffle is telescopically received and configured to have a clearance fit with the outer tube. The baffle may also include one or more outer edges configured to scrape debris from the inner surface of the outer tube when the baffle is removed from the outer tube.
