They have all machined parts, no MIM parts like you find on the 870 Express. All 870 accessories and parts will fit except the barrels. The barrel rings are in different locations on the barrels. H&R carries extra barrels when they aren't out of stock.
I own both Hawk 982 & Pardner Protector. They are my favorite utility pump guns.
Picture of the Hawk 982 with a after market 7+1 tube extension. It will also fit the Pardner Protector.
Good link on both shotguns:
