  • Patent number: 11781825
    Abstract: A gas block for AR-platform firearms is provided which is easier to install and index on a barrel of the firearm by utilizing a wedge (e.g., collet) system. The body of the gas block may therefore be relatively precisely circular, allowing for easy movement into position on the barrel of the firearm. The gas block is stronger, tighter, more durable, and more reliably stays in place than prior art gas blocks. In one embodiment, the gas block eliminates forward gas leakage from between the gas block and barrel. The gas block is interchangeable with standard prior art gas blocks commonly found on barrels of existing AR-platform firearms. The gas block is also compatible with low profile and MLOK handguards for AR-platform firearms.

    Abstract: A bi-directional seal assembly for sealing the annulus between an inner tubular member and an outer tubular member comprises an annular seal which in cross section includes a generally U-shaped first portion having a radially inner first leg and a radially outer second leg and a generally U-shaped second portion having a radially inner third leg and a radially outer fourth leg. The second and third legs are joined together such that the first leg engages the inner tubular member and the fourth leg engages the outer tubular member. Pressure below the seal urges the first leg into sealing engagement with the inner tubular member and forces the second and third legs radially outwardly to thereby urge the fourth leg into sealing engagement with the outer tubular member. Also, pressure above the seal urges the fourth leg into sealing engagement with the outer tubular member and forces the second and third legs radially inwardly to thereby urge the first leg into sealing engagement with the inner tubular member.

  • Patent number: 8104769
    Abstract: A liquid and gas tight bi-directional metal frustro-conical seal is energized by compression between planar, annular faces causing its inner and outer diameters to sealingly engage opposing cylindrical surfaces of inner and outer metal pipes. The contact forces between the concentric sealing surfaces are high in order to locally deform the softer metal and eliminate leakage paths. The sealing ring is backed-up by a similar ring that is reduced in cross-sectional width, such that when compressed the ring does not engage the inner and outer cylindrical surfaces. The second ring is nested with and directly below the sealing ring, and equally axially compressed when the joint is assembled. When the pipe joints are disassembled, the second ring serves to restore the seal ring to its original, deeper frustro-conical shape, allowing the pipe joints to be easily separated for reuse of the piping in a different location.
