Abstract
An assembly for mounting a handguard to a firearm utilizes a biasing element disposed intermediate the barrel nut and the interior end of the handguard and a clamping element also disposed intermediate the barrel nut and the interior end of the handguard but positioned opposite the biasing element about the perimeter of the barrel nut. One or both of the biasing element and clamping element have multiple surfaces which mimic portions of the exterior profile of the barrel nut to prevent any of longitudinal, axial, or radial misalignment of the handguard relative to the axis of the firearm barrel.
Claims16
An assembly apparatus for securing a handguard to a firearm having a barrel nut, the assembly apparatus comprises:
- a handguard having a first end with an interior diameter shaped to receive at least a portion of an exterior of the barrel nut;
- a biasing element disposable intermediate the barrel nut and the interior diameter of the handguard, the biasing element having first and second biasing surfaces disposable adjacent first and second exterior surface portions, respectively, of the barrel nut;
- a first mechanism for securing the biasing element intermediate the handguard and the barrel nut,
- a clamping element having first and second surfaces disposed adjacent first and second exterior surface portions, respectively, of the barrel nut;
- and
- a second mechanism for securing the clamping element intermediate the handguard and the barrel nut.
An assembly kit for use with a firearm having a barrel nut and a handguard, the kit comprising:
- a biasing element disposable intermediate the barrel nut and an interior diameter of the handguard;
- a first mechanism for securing the biasing element intermediate the handguard and the barrel nut,
- a clamping element having first and second surfaces disposed adjacent first and second exterior surface portions, respectively, of the barrel nut;
- and
- a second mechanism for securing the clamping element intermediate the handguard and the barrel nut.
A method for mounting a handguard to a firearm having a cylindrical barrel nut, the method comprising:
- A) disposing a first end of the handguard about a portion of the barrel nut;
- B) inserting a biasing element intermediate the first end of the handguard and the barrel nut at a first location about an exterior perimeter of the barrel nut;
- C) inserting a clamping element intermediate the first end of the handguard and the barrel nut at a second location opposite the first location about the exterior perimeter of the barrel nut, the clamping element having first and second surfaces disposed adjacent first and second exterior surface portions, respectively, of the barrel nut;
- and
- D) urging the clamping element against the barrel nut.
An assembly apparatus for securing a handguard to a firearm, the firearm having a barrel nut with an exterior perimeter, the assembly apparatus comprises:
- a handguard having a first end with an interior diameter shaped to receive at least a portion of the exterior portion of the barrel nut;
- and
- a first clamping element disposable intermediate the interior diameter of the handguard and a first location on the exterior perimeter of the barrel nut, the first clamping element having an arcuate surface with a first radius of diameter and disposable adjacent the first location on the exterior perimeter of the barrel nut,
- a second clamping element disposable intermediate the interior diameter of the handguard and a second location on the exterior perimeter of the barrel nut opposite the first location, the second clamping element having an arcuate surface with the first radius of diameter and disposable adjacent the second location on the exterior perimeter of the barrel nut,
- wherein one of the first and second clamping elements has a second arcuate surface having the second radius of diameter and disposable adjacent the exterior perimeter of the barrel nut.
