Rise Armament OS Kit: Essential AR-15 Small Parts in Magnetic Tin

Features

  • Magnetic base tin keeps parts organized
  • To-scale image on lid for easy part identification
  • Includes most commonly lost AR-15 parts
  • Essential springs, detents, and pins
  • Compact storage solution
  • Perfect for range bag or workbench

The Rise Armament OS Kit solves the lost parts problem by providing the small components that always seem to disappear during builds or maintenance. This kit works well for armorers needing backup parts on hand, home builders tired of ordering individual detents and springs, and anyone who’s launched a buffer retainer across the room. The magnetic tin keeps everything organized while the lid’s to-scale diagram helps identify parts quickly – bringing peace of mind to your AR-15 work with the exact parts you need when a spring decides to go rogue.
