The Shim Ring is an essential item for attaching handguards and outer barrels to standard and next generation M4s. When installing handguards and outer barrels, the installation position and angle may be misaligned or rattled due to dimensional discrepancies with the main body. By using this item, the barrel nut can be securely positioned and the rattling of the outer barrel can be eliminated, allowing for a tighter fixation! In order to meet the needs of various users, three different thicknesses (0.1/0.3/0.5mm) are included in the set!
