Updated BespokeGun recoil system

Constructively defined shot kinematics

When firing, the rifle begins to move before the bullet leaves the barrel.

It is at this moment that the primary error is formed: the weapon's position changes, the support conditions differ each time, and the repeatability of the series is disrupted.

Typically, this problem is "solved" by the shooter — through grip, hold, and technique. The BespokeGun recoil system is built on the opposite approach: the rifle's behavior must be determined by its design, not by the person.

Core concept

Recoil is not a side effect of the shot. It is a mechanical movement that can be defined by geometry.

The purpose of the recoil system is to ensure strictly linear movement of the rifle along the bore axis with no rotational components. Muzzle rise, canting, and lateral yaw are treated as consequences of improper kinematics, not as inevitabilities.

Why does shot error occur?

In the "traditional" scheme:

• part of the load is taken by the shooter,
• part — by the support surface,
• part — by elastic elements.

As a result, every shot occurs under new conditions. Even with identical aiming, the geometry of the system at the moment of the shot differs: the angle, the point of contact, and the nature of the return to the line of sight all change. The recoil system addresses precisely this problem — it does not stabilize the weapon, but makes its movement predictable.

Operating principle

The entire scheme is built as a kinematic system with separation of functions.

• The front support establishes the base geometry and fixes the initial position.
• The rear support accompanies the movement and maintains the trajectory.
• The shooter does not participate in recoil control.

Upon firing, the weapon should not be "held" — it should travel along a defined line.

Movement requirements

The recoil system must ensure:

• linear movement along the bore axis;
• absence of weapon rotation;
• absence of jerks and binding;
• consistent behavior from shot to shot;
• return to the line of sight without correction.

Any parasitic movements — vertical, lateral, or rotational — are eliminated by the geometry of the components, not by the shooter's technique.

Why are elastic elements excluded?

Springs, rubber, and dampers accumulate energy and release it differently each time. This makes recoil non-repeatable: every shot has a slightly different movement character.

Therefore, the recoil system has:

• no damping materials,
• no elements functioning as shock absorbers,
• no need to "catch" the rifle.

Modular architecture

The system is built as a set of independent modules.

Each element performs a specific mechanical function and can be used independently.

Main module groups:

• front support surface (mat-bag, front support module);
• bipod assemblies and support elements (skids, tips, base extenders);
• rigid mounting interfaces;
• forward extension of the support point;
• rifle linear travel module;
• rear support skid and rear support surface.

The modular design allows the system to be implemented incrementally and the geometry to be configured for a specific rifle and shooting conditions without modifying already installed equipment.

How does the BespokeGun system differ from conventional solutions?

Typically, accuracy is sought through:

• shooter skill,
• firmness of hold,
• dampening.

Here the approach is different: accuracy is achieved through the repeatability of the shot's mechanics.

The shooter is responsible for aiming. The design is responsible for weapon behavior.

Summary

The BespokeGun recoil system is a constructively defined kinematic scheme that ensures linear and repeatable rifle movement along the bore axis upon firing. Recoil is neither suppressed nor compensated. It occurs along a pre-defined trajectory and is independent of the shooter's actions.

Upcoming publications will showcase real system configurations, module compatibility, and examples of operation on various rifles.
