First Factory Outer Barrel Base for Standard AEG M4 Series

This product is intended to attach various free float handguards to the Tokyo Marui AEG Standard M4 series. In addition, you can customize the length to your liking by combining the separately sold outer barrel pieces
based on the "barrel base" . The barrel length can be changed to your liking by using the separately sold piece connection structure from the barrel base!! Adopts a flange shape that allows you to attach various free float rail handguards! You can choose the barrel length from as short as 4 inches. The joint part of each barrel piece is equipped with an O-ring to prevent loosening. Pure Japanese high-precision processing realizes a tight clearance with the inner barrel even with the connection structure! The outer barrel is also equipped with an O-ring on the inside, which firmly holds the inner barrel and improves the collection rate!

★Recommended for those who
want to change their stock handguard to a free-float handguard!

★[Important]
When installing a free-float handguard, in most cases it is necessary to replace the outer barrel!
This product is an outer barrel that can be changed to a different length, so it is highly versatile and will help you achieve your ideal customization! * Please use the "Outer Barrel Adjustment Shim Ring"


to adjust the fixation and eliminate rattling . * Please use the "Next Generation M4 Wrench <Tool>" sold separately to install and remove the outer barrel fixing ring of the next generation M4 .
