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.
