About this file
This document is a technical drawing for a 60mm Obturating Ring, Revision G dated March 6, 2014. The drawing specifies the design, material, and manufacturing requirements for this component, which is used in various 60mm mortar rounds, including the M720A2, M768, and M768A1. The key details include:
The Obturating Ring is made of polyoxymethylene (acetal) homopolymer material with specific melt flow rate and heat deflection temperature requirements. It must be gated at the center of the solid portion and have a finish of 125 all over. Functional acceptance criteria require the ring to fit freely over a 2.173 inch minimum diameter plug. This drawing was generated from a solid model and is CAD-maintained by the design activity. The drawing is distribution limited to the Department of Defense and its contractors.
The related federal contract opportunity is for the procurement of Obturating Rings in 60mm, 81mm, and 120mm sizes, to be used in various mortar systems. The solicitation number is W519TC-25-R-2003, issued by the Department of the Army Materiel Command Contracting Command Rock Island Arsenal.
