LBE Unlimited AR-10 .308 Barrel Nut 4130 Steel Black Phosphate

The LBE Unlimited AR-10 barrel nut is a replacement part that threads onto the upper receiver to secure the barrel in an AR-10 build chambered for .308 Winchester. It is intended for builders and gunsmiths assembling or repairing an AR-10 style rifle.

This barrel nut is machined from 4130 chromoly steel and finished in black phosphate. It is made to fit DPMS-pattern AR-10 and LR-308 upper receivers.

Because it is sold as a standalone part, it does not include a barrel or upper receiver. Confirm the receiver pattern before installation.
