Abstract
A bolt carrier for a firearm that includes a rolling element so as to provide improved alignment and reduced friction of the bolt carrier with the upper assembly and buffer tube as the bolt carrier executes a reciprocating motion. The bolt carrier includes a body that is generally cylindrical in shape having a first end and a second end. The body of the bolt carrier includes a first slot and a second slot. The first slot includes an upper opening and a lower opening. The second slot is proximate the second end of the body of the bolt carrier. The second slot includes an upper opening and a lower opening providing access to the interior volume of the second slot. A wheel is rotatably mounted within the second slot. The upper edge and lower edge of the wheel extends beyond the top side and bottom side of the body respectively.
Claims19
A bolt carrier for a firearm comprising:
- a body, said body being elongated and generally cylindrical in shape, said body having a first end and a second end, said body including a first slot, said first slot being journaled through said body intermediate a top side and a bottom side, said first slot having a first opening and a second opening;
- a second slot, said second slot being proximate said second end of said body, said second slot being journaled through said body intermediate said top side and said bottom side, said second slot being intermediate said second end of said body and said first slot;
- a rolling means, said rolling means being disposed within said second slot, said rolling means having an upper edge and a lower edge, said rolling means configured to provide axial alignment with the bolt carrier and a buffer tube within a firearm wherein the rolling means further provides a reduced friction reciprocating movement of the bolt carrier.
A bolt carrier for a firearm comprising:
- a body, said body being elongated and generally cylindrical in shape, said body having a first end and a second end, said body including a first slot, said first slot being journaled through said body intermediate a top side and a bottom side, said first slot having a first opening and a second opening, said first slot being oval in shape;
- a second slot, said second slot being proximate said second end of said body, said second slot being journaled through said body intermediate said top side and said bottom side, said second slot being intermediate said second end of said body and said first slot, said second slot being oval in shape;
- at least one wheel, said at least one wheel being disposed within said second slot, said at least one wheel having an upper edge and a lower edge, said at least one wheel being rotatably mounted within said second slot, said at least one wheel configured to provide axial alignment amongst the bolt carrier and a buffer tube within a firearm wherein the at least one wheel further provides a reduced friction reciprocating movement of the bolt carrier.
A bolt carrier for a firearm comprising:
- a body, said body being elongated and generally cylindrical in shape, said body having a first end and a second end, said body including a first slot, said first slot being journaled through said body intermediate a top side and a bottom side, said first slot having a first opening and a second opening, said first slot being oval in shape;
- a second slot, said second slot being proximate said second end of said body, said second slot being journaled through said body intermediate said top side and said bottom side, said second slot being intermediate said second end of said body and said first slot, said second slot being oval in shape;
- a wheel, said wheel being disposed within said second slot, said wheel having an upper edge and a lower edge, said wheel being rotatably mounted within said second slot, said wheel configured to provide axial alignment amongst the bolt carrier and a buffer tube within a firearm wherein the wheel further provides a reduced friction reciprocating movement of the bolt carrier;
- and
- an axle, said axle configured to rotatably mount said wheel, said axle configured to extend intermediate opposing sides of said body.
The bolt carrier as recited 17, in claim wherein said wheel further includes an upper edge said upper edge of said at least one wheel being configured to extend beyond said top side of said body.
The bolt carrier as recited 18, wherein said wheel further includes a groove, said groove being circumferentially disposed on said wheel.
