Abstract
An adapter for attaching sound suppressors or other auxiliary attachments, such as a grenade launcher, to a weapon having a flash suppressor mounted on the end of a gun barrel. The adapter includes an adapter pilot specific to the caliber of weapon. Interchangeable adapter pilots allow a single adapter system to be utilized on various weapons having different calibers.
Claims5
A system for connecting an auxiliary attachments to an associated weapon, the weapon including a flash suppressor mounted to an end of a gun barrel and having at least one circumferential groove formed in an outer surface thereof, the system comprising:
- a generally tubular collet including first connecting means at a first end for attaching the auxiliary attachment, a plurality of elongated segments at a second end of the collet with each segment separated by a slit from each other, at least one row of lug members formed on an inward side of each segment being adapted for seating in the circumferential groove of the flash suppressor, a cam surface formed on an outer surface of each of the segments, second connecting means positioned intermediate the first connecting means and the second end, and positioning means located within the inner periphery of the collet;
- a cam nut generally tubular in shape for inserting around said collet segments having connecting means at one end for connecting to the second connecting means of the collet and having a cam surface at the other end formed on an inward side of the cam nut for engaging the segments of the collet;
- and,
- an adapter pilot being selectively positioned in said collet, the adapter pilot having a hollow, open ended body defining an inner surface being circular in cross section, the body having an exterior cylindrical base formed at the first end, and an axial extension formed the second end, wherein the circumference of the base is dimensioned to engage the inner periphery of the collet and the axial extension is dimensioned relative to a caliber of the associated weapon, the first end of the body being adapted for abutting the positioning means of the collet, and wherein the circular cross section of the first end is greater than the circular cross section of the second end.

A system for attaching auxiliary attachments to a plurality of associated weapons each having a different caliber, wherein each of the weapons includes a flash suppressor having at least one circumferential groove formed in an outer surface thereof, the system comprising:
- a generally tubular collet including first connecting means at a first end for attaching the associated auxiliary attachment, a plurality of elongated segments at a second end of the collet with each segment separated by a slit from each other, at least one row of lug members formed on an inward side of each segment being adapted for seating in the circumferential groove of the associated flash suppressor, a cam surface formed on an outer surface of each of the segments, second connecting means positioned intermediate the first connecting means and the second end, and positioning means located within the inner periphery of the collet;
- a cam nut generally tubular in shape for inserting around said collet segments having connecting means at one end for connecting to the second connecting means of the collet and having a cam surface at the other end formed on an inward side of the cam nut for engaging the segments of the collet;
- and,
- a plurality of adapter pilots, wherein one of the plurality of adapter pilots is selectively positioned in said collet, the adapter pilot having a hollow, open ended body defining an inner surface being circular in cross section, the body having an exterior cylindrical base formed at the first end, and an axial extension formed the second end, wherein the circumference of the base is dimensioned to engage the inner periphery of the collet and the axial extension is dimensioned relative to a caliber of the associated weapon, the first end of the body being adapted for abutting the positioning means of the collet, and wherein the circular cross section of the first end is greater than the circular cross section of the second end.

A method for attaching an auxiliary attachment to an associated weapon including a flash suppressor mounted onto a gun barrel, the flash suppressor having at least one circumferential groove formed in an outer surface thereof, the method comprising the steps of:
- providing an adapter having a generally tubular collet including first connecting means at a first end for attachment to the auxiliary attachment, a plurality of elongated segments at a second end of the collet with each segment separated by a slit from each other, at least one row of lug members formed on an inward side of each segment being adapted for seating in the circumferential groove of the associated flash suppressor, a cam surface formed on an outer surface of each of the segments, second connecting means positioned intermediate the first connecting means and the second end, and positioning means located within the inner periphery of the collet;
- a cam nut generally tubular in shape for inserting around said collet segments having connecting means at one end for connecting to the second connecting means of the collet and having a cam surface at the other end formed on an inward side of the cam nut for engaging the segments of the collet;
- and, an adapter pilot being selectively positioned in said collet, the adapter pilot having a hollow, open ended body defining an inner surface being circular in cross section, the body having an exterior cylindrical base formed at the first end, and an axial extension formed the second end, wherein the circumference of the base is dimensioned to engage the inner periphery of the collet and the axial extension is dimensioned relative to a caliber of the associated weapon, the first end of the body being adapted for abutting the positioning means of the collet, and wherein the circular cross section of the first end is greater than the circular cross section of the second end;
- attaching the auxiliary attachment to the first connecting means of the adapter;
- selectively positioning the adapter pilot into the collet through the first end of the cam nut so that the first end of the adapter pilot abuts the positioning means of the collet;
- positioning the cam nut over the flash suppressor;
- positioning the collet around the flash suppressor so that the lug members are aligned with the circumferential groove of the flash suppressor;
- and,
- engaging the connecting means of the cam nut with the second connecting means of the collet to engage the lug members into locking engagement with the circumferential groove.
