Sounds like it's the new hotness amongst the sniper community. You can read the rest here:What I saw was a product that was elegant in its simplicity, rugged and effective. It was a most beautifully machined vice designed to hold a rifle and called the Hog Saddle. The Hog Saddle is the kind of product that you see and instantly realize the usefulness and application. Its the kind of product that makes you slap your forehead and say “I should have thought of this”. Its the kind of product that you realize meets a need you never knew you had or if you did realize you did have the need, this product instantly makes your life simpler and better.
The Hog Saddle is in essence, a 16 oz. CNC machined vise for your rifle with an industry standard mount that sits atop a commercial camera tripod. The singular purpose of The Hog Saddle is to provide a stable, solid, universal thread attachment for your rifle on a modular lightweight, adjustable and adaptable mount (tripod). It is crafted out of a single block of aluminum, hard anodized to provide a base for camouflage and is resistant to corrosion. The vice itself been machined to provide a contact patch of urethane pads to protect your rifle, reduce recoil and muzzle rise and preserve accuracy.
