Accounting Policies [Abstract]
Organization	Organization: Sturm, Ruger & Company, Inc. (the “Company”) is principally engaged in the design, manufacture, and sale of firearms to domestic customers. Approximately 99% of sales are from firearms. Export sales represent approximately 5% of total sales. The Company’s design and manufacturing operations are located in the United States and almost all product content is domestic. The Company’s firearms are sold through a select number of independent wholesale distributors, principally to the commercial sporting market. The Company also manufactures investment castings made from steel alloys and metal injection molding (“MIM”) parts for internal use in its firearms and for sale to unaffiliated, third-party customers. Approximately 1% of sales are from the castings segment.
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue in accordance with the provisions of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”), which became effective January 1, 2018. Substantially all product sales are sold FOB (free on board) shipping point. Customary payment terms are 2% 30 days, net 40 days. Generally, all performance obligations are satisfied when product is shipped and the customer takes ownership and assumes the risk of loss. In some instances, 8 Index sales include multiple performance obligations. The most common of these instances relates to sales promotion programs under which downstream customers are entitled to receive no charge products based on their purchases of certain of the Company’s products from the independent distributors. The fulfillment of these no charge products is the Company’s responsibility. In such instances, the Company allocates the revenue of the promotional sales based on the estimated level of participation in the sales promotional program and the timing of the shipment of all of the firearms included in the promotional program, including the no charge firearms. Revenue is recognized proportionally as each performance obligation is satisfied, based on the relative customary price of each product. Customary prices are generally determined based on the prices charged to the independent distributors. The net change in contract liabilities for a given period is reported as an increase or decrease to sales.
Fair Value of Financial Instruments	Fair Value of Financial Instruments: The carrying amounts of financial instruments, including cash, short-term investments, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to the short-term maturity of these items.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassifications	Reclassifications: Certain prior period balances have been reclassified to conform to current year presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842), its final standard on the accounting for leases. The most significant change in the new lease guidance requires lessees to recognize right-of-use assets and lease liabilities for all leases other than those that meet the definition of short-term leases. For short-term leases, lessees may elect an accounting policy by class of underlying asset under which these assets and liabilities are not recognized and lease payments are generally recognized over the lease term on a straight-line basis. This change results in lessees recognizing right-of-use assets and lease liabilities for most leases currently accounted for as operating leases under legacy U.S. GAAP. The new lease guidance was effective in fiscal years beginning after December 15, 2018 and interim periods thereafter. The Company adopted ASU 2016-02 effective January 1, 2019. As more fully discussed in Note 5, as a result of adopting ASU 2016-02, the Company recorded right-of-use assets totaling $2.5 million and lease liabilities of $2.5 million on its Consolidated Balance Sheets as of September 28, 2019. There was no impact on the condensed consolidated statements of income, condensed consolidated statements of stockholders’ equity, or condensed consolidated statements of cash flows as a result of this adoption.
