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, the body including openings in a side of the body; and a thumb paddle to engage an opening of the openings and extending from the side of the body to engage a thumb below the barrel and below the handguard or forestock, the thumb paddle to be positioned within the opening of the openings and fixed in a select position with a fastener, wherein the thumb paddle when fixed with the fastener is unmovable relative to the forward grip to provide mechanical leverage. ### Claim 2 (depends on 1) The forward grip of claim 1, further comprising a barrier 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 a position of 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 to secure a pressure pad to the body. ### 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 interface is configured to engage a Picatinny rail or Keymod mounting structure. ### Claim 9 (depends on 1) The forward grip of claim 1, wherein the thumb paddle is removable absent the fastener to be placed in different positions within the opening and fixed using the fastener. ### 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 (depends on 1) The forward grip of claim 1, wherein the body defines a cavity opening at the distal end of the body, the forward grip further comprising a back plate to cover the opening. ### Claim 13 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, the body including openings in a side of the body; and a thumb paddle to engage an opening of the openings and extending from the side of the body to engage a thumb below the barrel and below the handguard or forestock, the thumb paddle to be positioned within the opening of the openings and fixed in a select position with a fastener, wherein the thumb paddle when fixed with the fastener is unmovable relative to the forward grip to provide mechanical leverage. ### Claim 14 (depends on 13) The firearm of claim 13, further comprising a barrier structure extending downward from a distal end of the body. ### Claim 15 (depends on 13) The firearm of claim 13, wherein the forward grip has an angle in a range of 10° to 60° relative to an axis of the barrel. ### Claim 16 (depends on 13) The firearm of claim 13, further comprising a pressure pad keeper coupled to the body to secure a pressure pad to the body. ### Claim 17 (depends on 13) The firearm of claim 13, wherein the thumb paddle is removable absent the fastener to be placed in different positions within the opening and fixed using the fastener. ### Claim 18 (depends on 13) The firearm of claim 13, wherein the thumb paddle includes a polygonal post to engage the body at selectable angles.
