A3 Industries MPA Defender Modular Picatinny Vertical Foregrip - 2.5in Grenade Grip Black. Its 100-degree forward angle addresses the Defenders limited VFG space by improving wrist alignment providing additional hand clearance from the trigger guard and offering a more stable grip interface. Due to the proximity to the barrel use is recommended with the factory faux suppressor or a suppressor equipped with a thermal cover. The design mirrors the ergonomic approach used on the B&T TP9 where a 90degrees +10degrees angle creates a wider handhold better stability and improved clearance between the magazine and the grip. The base is machined from high-strength 6061 aluminum and is compatible with all four A3 aluminum grip options.
