B.R.S.S. is a revolutionary design with International Patents Register The develop team in Bolt Airsoft has created a powerful recoil system called B.R.S.S - Bolt Recoil Shock System. B.R.S.S is a revolutionary paten .The B.R.S.S is utilized an outstanding designation by kinetic energy reduced by piston which then switches to Recoil weight of stock tube and subsequently displacement occurred to reach the outcome of recoil simulator. Such novel devise has been gone through several tests and accordingly BRSS comes into existence!

The B.R.S.S. Recoil System U.S. Patent #: 8746226 B2 (Patent Approved):

1. Buffer weight/Buffer guide rod reduces lateral movement of the buffer weight.

2. Buffer springs are located inside the buffer weight/buffer to increase buffer weight traveling distance to increase recoil.

3. Buffer weight/Buffer impacts buffer tube end cap to increase force of recoil.

4. Lightest buffer weight compared to other brands of recoil AEGs to reduce wear of gearbox internals.

5. BOLTs recoil system includes dampening springs buffer guide rod to reduce impulse shock force to increase durability and also allowing for higher rate of fire.

6. Gearbox internals are compatible with standard Tokyo Marui spec parts.

Gearbox Internals:
1. Buffer pads are installed inside the piston to reduce impact force from the buffer guide rod and the spring to increase gearboxs durability.

2.Piston body is made out of 6061 T6 aircraft grade aluminum with full steel tooth.

Sector Gear:
1. Stamp steel process and powder metallurgy for high strength and reduce gear noise when cycling.

Spur Gear:
1. One piece steel spur gear made with Metal Injection Molding technology.

Bevel Gear:
1. Steel powder metallurgy with 10 Anti-Reversal Cuts to minimize back spinning of the gearbox.

Anti-Reversal Latch:
1. Brand new design to match the BOLT bevel gear for more efficient back spinning breaking.
