Vertical Foregrip Adapter, Limited Axial Rotation Version , fits MIL-STD-1913 (Picatinny) RailVersa-Pod M658 Tactical Limited Rotation This version is identical to the the 618 but with limited axial rotation. The Model 658 is extremely strong with an all steel chassis, and also extremely comfortable and durable with its PA66 molding. The PA66 molding gives this foregip superior strength without the added weight. It is a great alternative to the longer Model 616 and 656 when the extra length is not needed. The ribbed style grip is designed to allow the shooter positive grip in wet conditions even with gloves on. The tactical version includes a quick release sling loop to allow an additional point to attach your sling. Our foregrips allow reduced muzzle climb and greater accuracy with full-auto or burst fire. The Versa-Pod bipod can be folded up and out of the way or completly removed when not needed. The All-Steel spigot fits our Versa-Pod Classic Series and 50 Series bipod lines, and allows limited axial rotation. This foregrip adapter attaches to a standard MIL-STD-1913 Picatinny rail with our patented U-bolt and quick release thumb screw.
