This is an awesome, futuristic looking foregrip that mounts on picatinny rails.
You can mount this on M-LOK rails also, if you use this accessory.
From the Manufacturer
Designed for enthusiasts. In combination with the CQR buttstock, the HERA CQR fore-grip offers one of the most compact and ergonomic fixed-stock systems for the AR-15 / AR-10 platform, which is not only perfect for free-hand shooting, but also for tactical use. The QD eyelets also allow the inclusion of sling swivels with ball lock system. Made of impact-modified polymer, the CQR fore grip and buttstock also impress with their light weight. Available in black, tan and green.
All HERA polymer products are manufactured in Franconia, Germany.
