About this file
This is an engineering drawing for a Muzzle Cap, MOD1 (part number 53711-8905606-1), controlled by the Department of Navy under PMS 495. The drawing is classified as Controlled Unclassified Information (CUI) with Distribution Statement D, restricting dissemination to the Department of Defense and U.S. DoD contractors only, with critical technology designation as of November 2024. The document is subject to the Arms Export Control Act and Export Administration Act restrictions.
The muzzle cap is an aluminum assembly requiring specific manufacturing processes including anodizing per MIL-PRF-8625 (Type II, Class 1, No Seal), insertion of a grooved pin (Find Number 2) after anodizing, and application of dark grey epoxy paint (5-7 mils) per manufacturer instructions. The component features multiple dimensional specifications including outer diameters ranging from 17.00 to 18.990 inches with tight tolerances (±.010), internal bore specifications, and detailed thread specifications (17.938 ±.01 pitch diameter). Critical dimensions are controlled to datum references A, B, and C, with geometric controls including perpendicularity, position, and runout per ASME Y14.5M. The drawing references material specifications MIL-DTL-24441/23 Form 153 Type 3 and includes detailed cross-sectional views and feature details. Point of contact for questions is Eric Gonzalez, Department of Navy, (202) 781-1560.
