    About BOLT

    Bolt Airsoft excels in bringing realism to the Electric Airsoft rifle market through their patent pending Bolt Recoil Shock System (B.R.S.S. for short.) Their goal is to combine the advantages AEGs have such as performance, consistency, and reliability with the often sought after recoil impulse from a gas blowback system. This unique feature works by transferring the kinetic energy from the piston cycling to a weight system in the stock to generate the simulated recoil. Paired with high quality externals, Bolt Airsoft offers a line of excellent ready-to-play guns that also make for great starting platforms for project guns and upgrades.

    "This piston is amazing. For anyone with siegetek gears that tend to destroy pistons that are not full aluminum and steel, and canít get their hands on a shs piston this is the next best thing. I have shot about 5000 rounds with this piston and absolutely not stripage on this. The only con about the piston is the black paint chips off, other than that it is awesome. I was shooting around 47 rps at 430 with .20 bbs and an m120 spring and a perfect air seal. I have siegetek 20.8 ratio gears with a gate Titan and a G&p Satan m180 motor and canít complain about nothing.
