1、 INCH-POUND MIL-PRF-32366 26 November 2010 SUPERSEDING PRF13018853 10 October 2007 (See 6.5) PERFORMANCE SPECIFICATION GRIP/BIPOD, FORWARD This specification is approved for use by the U.S. Army Armaments Research, Development and Engineering Center (ARDEC) and is available for use by all Department
2、s and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification prescribes the performance requirements and identifies verification procedures for the Grip/Bipod, Forward, hereafter referred to simply as the Forward Grip/Bipod or FGB. The FGB provides the operator with a dual uti
3、lity as a forward grip and bipod for the M4 and M16 series rifle. 1.2 Requirement levels. This specification identifies two values for selected performance requirements. The threshold (T) is the minimum acceptable level. The objective (O) is the desired level at which performance of the FGB results
4、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 are specified in sections 3 or 4 of this specification. This section does not include documents ci
5、ted in other sections of this specification or recommended for additional information or as examples.
