7075 Aluminum BARREL NUT RG2 Series AR-15

I am a Gunsmith and receive "customer's" ARs for repair or barrel/handguard replacement. The barrel nuts are often buggered up. I bought 9 of the RG2 nuts to use as is or to modify as required BECAUSE most parts houses don't or won't sell replacement H/W for hand guards. BREEK ARMS does it quickly and at a friendly price. - Sebbie
