This application claims the benefits of U.S. Provi 1. FIG. 1 sets forth a line drawing of a firearm (100) that sional Application No. 62/074,268, filed Nov. 3, 2014, the includes a bayonet system (102) according to example disclosure of which is hereby incorporated by reference in embodiments of the present invention. The firearm (100) of its entirety including all figures, tables, drawings, descrip FIG. 1 is depicted as an M4 machine gun. The M4 machine tion and other disclosure. gun or carbine is a shorter and lighter variant of the M16A2 assault rifle. The M4 is often implemented as a 5.56x45mm NATO, air-cooled, direct impingement gas-operated, maga U.S. BACKGROUND Zine-fed carbine. It often has a 14.5 in (370 mm) barrel and 0002. A bayonet is typically implemented as a knife, a telescoping stock. The M4 is heavily used by the United Sword, or spike-shaped weapon designed to fit in, on, over States Armed Forces and is replacing the M16 rifle in most or underneath the muzzle of a rifle, musket, firearm, or United States Army combat units. The depiction of the M4 similar weapon, doubling the weapon also as a spear or and its use in describing removable and retractable firearm Sword. It is often considered an ancillary close-quarter bayonet systems in accordance with the present invention is combat weapon. Modern firearms often have rail systems for explanation and not for limitation. In fact, almost any allowing for additional or ancillary accessories to be firearm may be adapted for use in conjunction with remov attached. able and retractable firearm bayonet systems of the present invention including rifles, hand guns, automatic weapons, BRIEF DESCRIPTION OF THE DRAWINGS semi-automatic weapons and so on as will occur to those of skill in the art. 0003 FIG. 1 sets forth a line drawing of a firearm that (0012.

One difference between the Picatinny rail and the handle. similar Weaver rail are the size of these slots and the fact that they are typically standardized. Weaver rails often have a SUMMARY OF THE INVENTION slot width of 0.180 in (4.57 mm), but are not necessarily consistent in the spacing of slot centers. Some accessories 00.10 Example embodiments of removable and retract are designed to fit on both Weaver and Picatinny rails; but able firearm bayonet systems according to embodiments of most Picatinny devices will not fit on Weaver rails. Many the present invention are provided that include a blade and rail-mounted accessories may be attached with and come a mount. In typical embodiments, the blade is secured within with only a single recoil pin, avoiding the issue of differing the mount and the mount provides at least two secured slot spacing between various rail systems. The Picatinny rail positions. The Secured positions include a retracted position system is provided herein for explanation and not for wherein the blade is secured at least partially within the limitation. In fact, many rail systems may be used in mount and an extended position wherein the blade is secured conjunction with removable and retractable firearm bayonet to the mount with at least a portion of the blade extending systems according to embodiments of the present invention beyond the mount. In typical embodiments, the mount also including, but not limited to, the Weaver rail system, the includes one or more removable attachments to secure the NATO Accessory Rail system, and the Key Mod rail system mount to a rail system of a firearm. and many others as will occur to those of skill in the art.
