B5 Systems just officially released their new M-LOK Vertical Grip. I actually had a chance to work with this one a little early and covered it in my recent write up on B5 Stocks. It’s solid piece of kit and very reasonably priced at only $20.00.
Ergonomic Design: Engineered to provide superior comfort and control. The foregrips feature an ergonomic shape that fits naturally in the hand.
Enhanced Grip Texture: The surface texture on all four sides ensures a secure hold, even in wet or gloved conditions.
Durable Construction: Made from high-strength polymer, the foregrips are designed to withstand rigorous use while maintaining a lightweight short profile that does not add unnecessary weight to the firearm.
Versatile Mounting Options: Compatible with M-LOK® rail systems these foregrips are mountable in 2 directions.
Colors: Available in Black, FDE, Coyote Brown, OD Green, and Wolf Grey as well as hydro dipped Multicam®, Multicam® Black, and Woodland.
Looks like the BCM canted grip.
