Barrel Lock for M4 / M16 Chambers by ASG ULTIMATE

This small but important upgrade component is designed to secure the inner barrel in the correct position within the hop-up chamber. Thanks to its special cutout, the lock fits perfectly into the groove on the inner barrel and prevents it from rotating during chamber installation or when manipulating outer accessories like suppressors or barrel extensions.
Installing the barrel lock helps increase accuracy and maintain consistent performance by eliminating unwanted barrel shifts that could disrupt the BB trajectory. This part is designed for AEG barrels with a locking groove and is compatible with standard M4 / M16 hop-up chambers following the Tokyo Marui spec.
