The LBE Unlimited ARBNT Barrel Nut provides secure barrel attachment for AR-15 platform rifles with precision-machined steel construction. This essential component ensures proper headspace and barrel alignment while withstanding the stress of repeated firing cycles.
What Makes This Different
Unlike standard aluminum barrel nuts, the ARBNT features hardened steel construction that resists deformation under torque loads up to 80 foot-pounds. The precision threading maintains consistent headspace measurements within 0.001 inches. Standard mil-spec dimensions ensure compatibility with most AR-15 upper receivers and barrel extensions.Key Features
