"DHR" Accuracy International rifle stock system bipod spigot adaptor with "Slot Stud" technology. The DHR adaptor will will accept any bipod that either attaches to a Picatinnay rail or to a sling stud attachment. A feature that is Patent Pending to Alamo Four Star and Phoenix Tactical is the "Slot Stud" technology. The Slot Stud is milled directly into the Picatinnay spec. rail system eliminating a rifle sling stud. If you have a Harris type bipod you may attach directly into and bed the rail directly onto the bipod replacing any rail attachment devices that you were previously required to use. The additional benefits of having a bipod mounted directly on the front of the stock and more near the center of the rifle adds a lower center of gravity and a longer balance point that users of the Parker Hale bipod have enjoyed for years. The systems measure 4" in length, and operate on/off the rifle with the original Accuracy International release lever. Additionally, the system was designed to lock to the front of the AI bipod spigot shelf fully enabling the use of a Pod-Loc device with the Harris bipod systems while also lowering the rifle for better control. These are made of 6061 T-6 aluminum with Type III black and soon to be released "Recon Brown" hard coat anodizing with a steel attachment shaft that is fully adjustable for a custom tight fit for each user. 4-6 weeks for delivery.
