Ballistic-Optimized Rifling
Every Shot, Perfectly Aligned.
Optimized Projectile Flight · Chamber-Pressure Harnessing
Overview
DureTek’s Ballistic-Optimized Rifling is a proprietary rifling technology engineered to do two things at once: stabilize the projectile in flight and put chamber pressure to work. By ensuring the projectile is perfectly aligned with the barrel at the instant of firing, it raises both shot-to-shot consistency and firing efficiency at their source.
The Challenge
Small arms accumulate minute mechanical errors — through manufacturing tolerances and through repeated use. When the projectile’s central axis drifts out of line with the barrel’s centerline, the round leaves the barrel without engaging the rifling cleanly, and its trajectory turns unstable. These errors are invisible to the eye, yet they act directly on accuracy and effective range.
Our Approach
DureTek reinterpreted rifling not as a means of merely spinning the projectile, but as a critical interface that optimizes flight and firing energy together. By correcting alignment errors and trajectory instability, we ensure the round engages the rifling precisely — while a purpose-built geometry channels chamber pressure directly into projectile velocity.
The result is a single rifling technology that meets two goals at once: harnessing firing energy without waste, and securing the projectile’s stability in flight.
Key Benefits
1. Enhanced Firing Efficiency
By putting chamber pressure to work, the technology increases muzzle velocity by approximately 10 m/s (based on in-house testing).
2. Superior Shot Consistency
Correcting alignment errors delivers a stable, repeatable trajectory — shot after shot.
3. Extended Effective Range
Greater flight stability and higher velocity combine to extend effective range.
4. Trajectory Stability
Precise engagement between projectile and rifling minimizes trajectory instability.
Versatility
Ballistic-Optimized Rifling can be applied without a full overhaul of the chamber structure. It works broadly with conventional ammunition and is optimized to deliver its peak performance when paired with DureTek’s high-performance rounds.
Our Commitment
DureTek holds full intellectual property rights to its Ballistic-Optimized Rifling technology and is committed to bringing it first to Korea’s small arms modernization programs. With a technology that unites precision and efficiency, we intend to establish our presence in the global defense market.
