Learn how to install a longer inner barrel in your Silverback VKS.

This example uses a 578 mm SRS 22" inner barrel in place of the factory 350 mm inner barrel.

Maximum supported barrel lengths are:

Full Size Suppressor: up to 571 mm, fully supported by a barrel spacer.
Half Size Suppressor: up to 467 mm, fully supported by a barrel spacer.

You will need 20 mm barrel spacers (SBA-BBS-10 : silverback-airsoft.com/bbs-10) to extend your inner barrel inside the VKS silencer.

Longer barrels can also be installed, but without front support from a barrel spacer.
