Description

The ARROW M4 Bolts pack supplies M4 x 20mm fasteners for airsoft M4 and M16 platforms, where they can be used to secure rail systems, stocks, external accessories and receiver components. Each bolt is made from high-tensile steel alloy with a protective black oxide coating, and the metric internal hex socket takes a standard hex key.

The coating helps the bolts resist corrosion, while the hardened alloy is intended to cope with the vibration and movement of regular field use. With an M4 x 20mm thread that matches rail and body mounting points, the multi-pack is a practical way to replace worn, stripped or missing factory screws and keep mounts tight on a custom build. It suits airsoft technicians, gunsmiths and players who maintain their own rifles.

  • M4 x 20mm metric thread
  • High-tensile steel alloy construction
  • Protective black oxide finish
  • Internal hex socket drive
  • Suits airsoft M4 and M16 rail and body mounts
