LBE Unlimited AR-15 Barrel Nut 4130 Steel Manganese Phosphate

The LBE Unlimited ARBNT is a barrel nut for the AR-15 platform. It threads onto the barrel extension and secures the barrel to the upper receiver, and it is the part that holds the handguard in place at the front of the upper.

The nut is machined from 4130 steel and finished in manganese phosphate, which gives it a black color and a surface treatment suited to a rifle component. It is listed as fitting AR-15 upper receivers.

Because it is a platform-specific part, confirm that your upper receiver and barrel extension are AR-15 compatible before installing it.
