Deceleration Buffer System

We have developed the Deceleration Buffer System (DBS) — a system that eliminates shock and vibration of the firearm’s moving parts on AR platforms, significantly changing the character of recoil.

Controlled deceleration of the moving parts, together with increased pressure during the final chambering and locking phase, gives the shooter a softer, smoother impulse, improved comfort, and better control of the rifle while maintaining reliability.

The entire system is designed for a standard mil-spec buffer. DBS supports reliable operation across different configurations — with various types of ammunition and muzzle devices.

How it works

DBS uses the principles of an induction brake, which you may know from high-speed trains. By using a standard mil-spec buffer tube as the inductor, we were able to transfer this physical principle into the AR-15 platform without any modifications to the firearm’s design.

The system contains no complicated mechanical parts, so there is nothing to break. This patented technology gradually dissipates energy that, in conventional systems, appears as a hard buffer impact at the bottom of the buffer tube.

At the end of the cycle, during locking, the system creates increased pressure in the locking phase by approximately 13 N above the static spring force, supporting consistent return-to-battery and reliable function — all without increased friction.

Compatibility

DBS is suitable for rifles built on the following platforms: AR-15, AR-9, AR-10, and AR-12.

Test results

Our latest analyses show a very significant improvement compared to a standard setup. The graphs compare a standard H1 buffer + standard spring versus DBS.
