The rail system can include a plurality of powered rails and at least one control rail. The rail system can be disposed on a firearm, extending along the barrel toward a front of the firearm. The front or forward direction of the firearm extends from the trigger toward the distal end of the barrel. The rail system can extend along the barrel forward of the trigger, stock, and firearm handle. ## Claims ### Claim 1 A forward grip to couple to a firearm, the firearm including a trigger, a handle, a barrel extending forward from the trigger and the handle, and a handguard or forestock extending along the barrel, the forward grip comprising: an interface to engage the handguard or forestock forward of the trigger and handle; a body extending downward and rearward from the interface, the body defining an index finger grip surface and defining at least a second grip surface downward and rearward of the index finger grip surface and separated from the index finger grip surface by a ridge; and a thumb paddle extending from a side of the body to engage a thumb below the barrel and below the handguard or forestock, the thumb paddle providing leverage to the body when engaged by the thumb, the thumb paddle immovable relative to the body when secured to the body. ### Claim 2 (depends on 1) The forward grip of claim 1, further comprising a buffering structure extending downward from a distal end of the body. ### Claim 3 (depends on 1) The forward grip of claim 1, wherein the grip has an angle in a range of 10° to 60° relative to an axis of the barrel. ### Claim 4 (depends on 1) The forward grip of claim 1, wherein the index finger grip surface is adjustable. ### Claim 5 (depends on 1) The forward grip of claim 1, further comprising a pressure pad keeper coupled to the body, the pressure pad keeper to receive a pressure pad of a lighting device. ### Claim 6 (depends on 5) The forward grip of claim 5, wherein the pressure pad keeper is disposed on a top surface of the body over the second grip surface. ### Claim 7 (depends on 5) The forward grip of claim 5, wherein the pressure pad keeper is disposed on a side surface of the body in proximity to the second grip surface. ### Claim 8 (depends on 1) The forward grip of claim 1, wherein the thumb paddle is configured to be repositioned to select positions along the side of the body when not secured to the body. ### Claim 9 (depends on 8) The forward grip of claim 8, wherein the thumb paddle is rotatable when positioned at a select position and not secured to the body. ### Claim 10 (depends on 1) The forward grip of claim 1, wherein the thumb paddle includes a polygonal post to engage the body at selectable angles. ### Claim 11 (depends on 1) The forward grip of claim 1, further comprising a second thumb paddle extending from an opposite side of the body relative to the thumb paddle. ### Claim 12 A firearm comprising: a trigger; a handle adjacent the trigger; a barrel extending forward from the trigger and the handle; a handguard or forestock extending along the barrel; and a forward grip comprising: an interface to engage the handguard or forestock forward of the trigger and handle; a body extending downward and rearward from the interface, the body defining an index finger grip surface and defining at least a second grip surface downward and rearward of the index finger grip surface and separated from the index finger grip surface by a ridge; and a thumb paddle extending from a side of the body to engage a thumb below the barrel and below the handguard or forestock, the thumb paddle providing leverage to the body when engaged by the thumb, the thumb paddle immovable relative to the body when secured to the body. ### Claim 13 (depends on 12) The firearm of claim 12, further comprising a buffering structure extending downward from a distal end of the body. ### Claim 14 (depends on 12) The firearm of claim 12, wherein the forward grip has an angle in a range of 10° to 60° relative to an axis of the barrel. ### Claim 15 (depends on 12) The firearm of claim 12, wherein the index finger grip surface is adjustable. ### Claim 16 (depends on 12) The firearm of claim 12, further comprising a pressure pad keeper coupled to the body, the pressure pad keeper to receive a pressure pad of a lighting device. ### Claim 17 (depends on 16) The firearm of claim 16, wherein the pressure pad keeper is disposed on a top surface of the body over the second grip surface. ### Claim 18 (depends on 16) The firearm of claim 16, wherein the pressure pad keeper is disposed on a side surface of the body in proximity to the second grip surface. ### Claim 19 (depends on 12) The firearm of claim 12, wherein the thumb paddle is configured to be repositioned to select positions along the side of the body when not secured to the body. ### Claim 20 (depends on 12) The firearm of claim 12, wherein the thumb paddle is rotatable when positioned at a select position and not secured to the body.
