Barrel flexing mitigation assembly

1. A barrel flexing mitigation assembly adapted for mitigating flexing of a barrel of a rifle during a firing process, wherein the rifle includes a stock, an action having a breech bolt carrier assembly, and a barrel terminating in a muzzle, the barrel flexing mitigation assembly comprising:

an elongate, tubular shaft extending coaxially with the barrel from the muzzle to the stock, such that the tubular shaft defines a rigid exoskeleton within which the entire rifle is encased and within which all moving parts, including the breech bolt carrier assembly, slide; and

an elongate, tubular barrel stabiliser which is snug-fitted with a matching interface geometry and engaged to fit over at least a portion of the barrel, such that the tubular barrel stabiliser is radially positioned between the barrel and the tubular exoskeleton and stabilises the barrel into radial contact with the exoskeleton;

the barrel flexing mitigation assembly being such that the exoskeleton and barrel stabiliser jointly mitigate and absorb radial displacement of the barrel while a projectile is being fired.

2. The barrel flexing mitigation assembly according to claim 1 , wherein the barrel stabiliser includes:

a tubular body which is snug-fitted over the barrel such that the tubular body engages an exterior wall surface of the barrel, and

at least one spacer radially extending from the tubular body and dimensioned for pressing against an interior wall surface of the exoskeleton,

the barrel flexing mitigation assembly being such that a radial chambers is defined between the tubular body of the barrel stabiliser and the exoskeleton.

3. The barrel flexing mitigation assembly according to claim 2 , wherein the barrel stabiliser includes:

a number of spacers that radially extend between the tubular body and the exoskeleton such that the spacers frictionally engage the tubular body with the exoskeleton, wherein

the spacers are positioned at regular intervals along a length of the tubular body such that a radial chamber is formed between each set of neighbouring spacers, the tubular body and the exoskeleton.

4. The barrel flexing mitigation assembly according to claim 1 , wherein the barrel stabilisers is operatively associated with a securing assembly to secure the barrel stabiliser onto an exterior wall surface of the barrel so as to prevent axial displacement of the barrel stabiliser in use, the securing assembly being located coaxially with and on opposite sides of the barrel stabiliser.

5. The barrel flexing mitigation assembly according to claim 1 , wherein the barrel stabiliser is heat conductive such that the barrel stabiliser serves as a heat sink, adapted to disperse heat away from the barrel during firing.

6. The barrel flexing mitigation assembly according to claim 1 , wherein the tubular exoskeleton is a rigid metal exoskeleton adapted to provide strength and rigidity to the barrel, the exoskeleton having any cross-sectional profile including circular, rectangular, square, hexagonal, octagonal, triangular or variations thereof.

7. A rifle including a stock, an action having a breech bolt carrier assembly, a barrel terminating in a muzzle and a barrel flexing mitigation assembly, wherein the barrel flexing mitigation assembly comprises:

an elongate, tubular shaft extending coaxially with the barrel from the muzzle to the stock, such that the tubular shaft defines a rigid exoskeleton within which the entire rifle is encased and within which all moving parts, including the breech bolt carrier assembly, slide; and

an elongate, tubular barrel stabiliser which is snug-fitted with a matching interface geometry and engaged fit over at least a portion of the barrel, such that the tubular barrel stabiliser is radially positioned between the barrel and the tubular exoskeleton and stabilises the barrel into radial contact with the exoskeleton;

the barrel flexing mitigation assembly being such that the exoskeleton and barrel stabiliser jointly mitigate and absorb radial displacement of the barrel while a projectile is being fired.

8. The rifle according to claim 7 , wherein the rifle the barrel is a full-length, rifled barrel.
