Description:

Introducing the AR-15 MK4 FEDERAL SUPER MODULAR RAILS by GEISSELE AUTOMATICS

The AR-15 MK4 Federal Super Modular Rails are engineered for reliability and performance, making them an ideal choice for serious shooters and professionals alike.

Product Description

This is the same rail used to fulfill contracts for the Federal Bureau of Investigation (FBI). Its strength, modularity, and M-Lok compatibility provide users with the capabilities needed to successfully complete the mission at hand.

These rails are purpose-built and feature integrated M1913 picatinny rail sections at the fore of the rail in the 3, 6, and 9 o’clock positions. The Picatinny rail on the bottom of the rail, or the 6 o’clock position, is elongated in this version to accommodate accessories more comfortably.

Maximum venting for heat dissipation dramatically reduces the rail's overall weight while maintaining its strong and rigid platform. The MK4 M-LOK rail features M-LOK slots at the 3, 6, and 9 o’clock positions as well as the upper 45° quadrants. This design allows the user to keep the weight on the rail system down while maintaining the modularity and versatility to attach accessories as necessary.

Available Options

  • Available in Black, DDC, Gray, and OD Green
  • All rails are 10” long
  • Made of Aluminum and feature M-LOK slots

Enhance your firearm's functionality with the AR-15 MK4 Federal Super Modular Rails—where quality meets innovation.
