Abstract: A firearm flotation system with a rearward buoyant body and a forward buoyant body is disclosed. The forward buoyant body may have a keyed rail slot constructed to allow the firearm rail system to be inserted therein. Alternatively, or in addition to, the forward buoyant body may include a first buoyant body portion and a second buoyant body portion. The first buoyant body portion has an interlocking tongue and the second buoyant body has an interlocking groove, wherein the tongue fits into the groove and connects the first buoyant body portion to the second buoyant body portion. The system is sufficiently buoyant to render the firearm buoyant in water when the firearm is attached to the system.

Abstract: A firearm flotation device for providing buoyancy to a firearm is disclosed. The device includes a buoyant body with a first buoyant body portion and a second buoyant body portion, wherein the first buoyant body portion includes an interlocking tongue and the second buoyant body includes an interlocking groove. The tongue fits into the groove and connects the first buoyant body portion to the second buoyant body portion. The buoyant body is sufficiently buoyant to render the firearm buoyant in water when the firearm is attached to buoyant body. The tongue-in-groove system may be tapered.

Abstract: A rifle flotation device for providing buoyancy to a rifle with a rifle rail system is disclosed. The device includes a buoyant body with a first and second keyed rifle rail slots constructed to allow the rifle rail system to be inserted therein. The buoyant body may further include a first buoyant body portion that includes the first keyed rifle rail slot and a second buoyant body portion that includes the second keyed rifle rail slot. The first buoyant body portion is detachable from the second buoyant body portion and the body may further include an interlocking tongue-in-groove system that attaches the first buoyant body portion to the second buoyant body portion.
