Action Army 6.03mm VSR-10 Barrel 550mm

The Action Army 6.03mm VSR-10 Barrel 550mm.  Fits inside the VSR10 Sniper Rifle (regular pro version) but is greatly extended with its longer length.  Works with Tokyo Marui and clone VSR10 airsoft sniper rifles.  This is a 6.03 inner barrel diameter, so it allows for less jams and tolerances than the 6.01mm.  A very popular choice as an alternative to the Prometheus.  One piece high grade metal machined.  Precision smooth inner bore with nickel plating.  This inner barrel is an upgrade to improve your gun's performance, accuracy, FPS, and range compared to stock gun barrels.

Use this if you extend your rifle out with a longer outer barrel and/or faux suppressor.
