Axially offset foregrip for a firearm and related devices, systems, and methods

A long gun comprising:

• a fore-end comprising a barrel having barrel axis;
• an axially offset fore grip sub-assembly coupled to the fore-end, the foregrip sub-assembly comprising:
• a grip portion having a first grip axis defined by a longitudinal axis of the grip portion, the grip portion having a first end, a second end, and a middle portion located between the first end and the second end, the middle portion configured to be grasped by a hand of a user about the first grip axis during use of the long gun;
• a coupling portion coupled to the middle portion of the grip portion, the coupling portion having a coupling axis defined by a longitudinal axis of the coupling portion, the coupling axis being substantially perpendicular to the first grip axis, the coupling portion configured to be coupled to a fore-end of a long gun having a barrel axis defined by a longitudinal axis of the barrel, such that the coupling axis is perpendicular to the barrel axis;
• and an adjustment mechanism configured to:
• selectively allow the grip portion to be rotated about the coupling axis;
• and selectively fix the grip portion in a plurality of rotational positions about the coupling axis, each rotational position defining an angle between the grip axis and the barrel axis between 60 degrees and 120 degrees with respect to a muzzle of the barrel.
