CMMG Free Float Handguards Barrel Nut Features The CMMG Free Float Handguards Barrel Nut is built from steel for long-term durability under the stress of barrel installation and torque. It is engineered to index correctly with CMMG s free float handguard systems ensuring proper handguard alignment and a secure wobble-free attachment to the upper receiver. This compatibility matters to builders because a mismatched or improperly indexed barrel nut can cause handguard rotation or baffle strikes on a suppressed build. Using the correct CMMG barrel nut keeps the free float design intact preserving the accuracy benefits that a free-floated barrel is meant to deliver. Finished in black the barrel nut blends with most AR-15 builds and resists the wear that comes from repeated assembly and disassembly. It is intended specifically for CMMG AR-15 free float handguards making it an easy correct-fit replacement part for armorers and home builders alike. Because it is sold on its own it allows a builder to source just the nut needed to complete a handguard swap without purchasing an entire kit. For anyone building repairing or upgrading a CMMG-compatible AR-15 upper this barrel nut is a simple dependable foundation for the free float handguard setup.
