Firearm compensator
In some embodiments, a firearm muzzle device comprises a body comprising an internal passageway comprising a first portion and a second portion. The first portion comprises a larger cross-sectional area than the second portion. A plurality of first vents are each in fluid communication with the first portion. A plurality of second vents are each in fluid communication with the second portion.
1. A firearm muzzle device comprising:
a body comprising an internal passageway, a plurality of first vents and a plurality of second vents;
the internal passageway consisting of a first cylindrical portion, a tapered portion and a second cylindrical portion;
the first cylindrical portion comprising a larger cross-sectional area than the second cylindrical portion;
each first vent in fluid communication with the first cylindrical portion; and
each second vent in fluid communication with the second cylindrical portion;
wherein no vent is in direct fluid communication with the tapered portion.
2. The device of claim 1 , each first vent comprising a slot.
3. The device of claim 1 , each first vent comprising a tube.
4. The device of claim 1 , wherein a cross-sectional area of the first portion is at least 3 times a cross-sectional area of the second portion.
5. The device of claim 1 , wherein a total cross-sectional area of the plurality of first vents is greater than a cross-sectional area of the first portion.
6. The device of claim 5 , wherein a total cross-sectional area of the plurality of second vents is greater than the total cross-sectional area of the plurality of first vents.
7. The device of claim 1 , wherein a total cross-sectional area of the plurality of second vents is greater than a total cross-sectional area of the plurality of first vents.
8. The device of claim 1 , wherein a total cross-sectional area of the plurality of second vents is at least 1.5 times a total cross-sectional area of the plurality of first vents.
9. The device of claim 1 , each first vent comprising a longitudinal axis oriented at a non-orthogonal angle to a central axis of the internal passageway.
10. The device of claim 9 , each second vent comprising a longitudinal axis oriented at a non-orthogonal angle to the central axis of the internal passageway.
11. The device of claim 10 , wherein the longitudinal axis of a first vent is parallel to a longitudinal axis of a second vent.
12. The device of claim 10 , wherein the longitudinal axis of each first vent is parallel to a longitudinal axis of a second vent.
13. The device of claim 1 , the plurality of second vents comprising a first row of second vents and a second row of second vents.
14. The device of claim 13 , wherein a cross-sectional area of each second vent in the first row is less than a cross-sectional area of each second vent in the second row.
15. A firearm muzzle device comprising:
a body comprising an internal passageway comprising a central axis, a plurality of first vents and a plurality of second vents;
the internal passageway consisting of a first cylindrical portion, a tapered portion and a second cylindrical portion;
the first cylindrical portion comprising a larger cross-sectional area than the second cylindrical portion;
each first vent in fluid communication with the first cylindrical portion, each first vent comprising a longitudinal axis oriented at a non-orthogonal angle to the central axis; and
each second vent in fluid communication with the second cylindrical portion, each second vent comprising a longitudinal axis oriented at a non-orthogonal angle to the central axis.
16. The device of claim 15 , wherein a total cross-sectional area of the plurality of second vents is greater than a total cross-sectional area of the plurality of first vents.
17. The device of claim 15 , wherein no vent is in direct fluid communication with the tapered portion.
