2、 available for use by all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification prescribes the performance requirements and identifies verification procedures for the Bipod, Squad Designated Marksman (SDM), hereafter referred to simply as the SDM Bipod. The SD

3、M Bipod provides a stable firing platform for the M4 and M16 series weapons. The SDM Bipod shall have the ability to adjust cant and leg height for leveling on uneven surface. 1.2 Requirement levels. This specification identifies two values for selected performance requirements. The threshold (T) is

4、 the minimum acceptable level. The objective (O) is the desired level at which performance results in an operationally significant increase in capabilities. When only one requirement is stated, it is the threshold requirement. 2. APPLICABLE DOCUMENTS 2.1 General. The documents listed in this section

5、 are specified in sections 3 or 4 of this specification. This section does not include documents cited in other sections of this specification or recommended for additional information or as examples.
