Our take: JBU, under licensing from Olympic Arms, has crafted a full metal airsoft replica of the highly sought after Free-float Integrated Rail System Handguard (FIRSH). The JBU Olympic Arms FIRSH is CNC machined from lightweight aluminum, with four integrated rails for attaching a wide variety of external accessories. Unlike many other railed hand guards with screwed on or riveted rails, the JBU Olympic Arms FIRSH is machined from a solid piece of aluminum, providing added stability and support.
This Olympic Arms FIRSH hand guard, by JBU, is designed for standard M4 AEGs and attaches directly to the lower receiver. The FIRSH hand guard also is much more sturdy than standard M4 rail systems, with absolutely zero wobble! All necessary components for installation are included, such as the CNC machined barrel nut, tightening tool, tension bolts, and Allen wrench. This is the perfect addition to your standard M4 AEG, providing a modern look and modular capabilities.
The JBU Olympic Arms FIRSH should be compatible with most metal gearbox M4 AEGs, with no modification required. Professional installation is recommended for anyone unfamiliar with installing a new rail interface system.
Precision manufactured to ensure durability and high quality.
Length: 7.125" in.
Weight: 11.1 oz.
Compatibility: Fits most metal gearbox M4 AEGs
Note: Ready to use right out of the box, though professional installation is recommended/may be required. Please consult a certified airsoft technician before installing to make sure that your AEG is compatible.
