Compatibility / To Determining the inner barrel length you need:
This barrel is compatible with all Tokyo Marui system AEGs The key to choosing an optimized inner barrel is to prevent it from exposing out of your outer barrel (or flashhider and mock silencer extensions) while maximizing it's length for optimized performance. Please note that the stock barrel length in your gun may not always be optimized for mass production models.
To determine the length you need, measure from where the magazine feed the bb to the tip of your inner barrel, or where you want your inner barrel to end. Subtract ~5mm for hopup unit. Remember, it is perfectly okay to have an inner barrel shorter than your outer barrel, or have the exposed sections hidden in a longer flashhider or mock silencer.

Inner Barrel FAQ: If you greatly increase the inner barrel of your AEG, you may want to make sure your gearbox Cylinder is adequate. (For example, if you install a 509mm inner barrel on your MP5, you may want to switch the cylinder to a full cylinder so the amount of air inside the cylinder is equivalent to your new barrel.

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.
