Abstract: A method of assembling a bolt handle to a bolt assembly of a firearm includes inserting the bolt handle through a handle opening defined by a bolt body. A distal end of the bolt handle is inserted through the handle opening until the distal end extends past an outer perimeter of the bolt body. At least a portion of a bolt shroud is inserted through a first portion of an aperture defined by the bolt handle. A force is applied to the bolt shroud while the bolt handle is retracted within the handle opening of the bolt body so that the bolt shroud is positioned within a second portion of the aperture. The bolt shroud is held in connection with the bolt handle when the bolt shroud is positioned within the second portion of the aperture to secure the bolt handle to the bolt body.

Abstract: Oil dispersible ferrous metal corrosion inhibitors are prepared by first forming a primary amine-terminated amide adduct by reacting a mixture of monomeric, dimeric and trimeric 1,6-hexanediamine with polyfunctional acids at a ratio of reactants such that the adduct is substantially completely terminated with primary amine groups and neutralizing the primary amine-terminated amide adduct with a carboxylic acid. Alternatively, water dispersible adducts may be prepared by reacting the primary amine-terminated amide adduct with an oxirane compound to produce a polyether derivative of the amine-terminated adduct.
