Hera Arms IRS AR-15 Quad Rail Handguard 16.5" Black

The Hera Arms IRS Handguard is one of the leading systems on the market, thanks to the consequent implementation of the integral approach, the reduced diameter and the dedicated barrel nut. All HERA Handguards are interchangeable to provide a consistent platform throughout different generations and models. All Hera handguards and barrel nuts are compatible with the AR15/M4 platform. The IRS System can also be used on platforms using a barrel nut thread compatible to the AR15/M4 system.
