Got a Hitachi nail gun that needs a fix? This listing is for a 2-pack of replacement handle arms, part number 884-066 (also listed as 884066). These are made to fit several models in the Hitachi NR83A series, including the NR83A2, NR83A2(S), NR83A3, and NR83A3(S). If your nailer’s handle arm is cracked, broken, or just worn out, this is the part you’ll likely need to get it back in action. Each pack comes with two handle arms, which is handy if you’re doing repairs often or just want a spare on hand. Always make sure to check your tool’s exact model number to confirm this is the correct part before you order. Replacing worn parts can help keep your nail gun safe and functioning properly for your next project.
